I installed these ducts on my 2002 C5 and I love it! No issues with road debris,etc. they should have come from the factory this way!
It's a good idea if you track your car but it's a bad idea if you have it just for regular driving .. cuz there's a material fly through it and hit the side doors case chip paint or damage the side doors that's why gm they don't add that... it's personal choice
i have them on my C5 that iv daily drove year round since i got it in early 2020 and i dont have this issue then again mine also has a screen or mesh on them too so
Nice video I didn’t see you subscriber count earlier, I am really surprised that the video is so clean keep it up
Thank you! I appreciate that! I'm trying to consistently improve my quality one video at a time!
Great video and explanation.
Thank you!
C5 side ducts pull air from the engine compartment helping control heat build up under the hood. Shine a light down by the brake master and it will shine through the vent.
I can't quite tell if that is actually its intended purpose or if that's more of an incidental thing. If it's intentional, then it was just terribly designed, because two of the biggest things the C5 is known for are
A.) Floating front-end from high pressure under the hood, and
B.) Poor heat management in the engine bay
Personally, I lean toward it being an incidental thing, because if it was a purposeful design, they failed miserably.
I like this benefit
Awesome vette 👍
I used fiber glass to direct engine bay heat out the side vents. These are cool though, however I would be concerned about rocks and dirt getting shot down the side of the car from the tires. Best place to vent wheel well pressure is out the top either through a custom fender vent or to join the top of the wheel well into the engine bay and have a hood vent.
No issues with debris,road spray,etc.
Nice lawn!!
Wicked. That's the red devil of hotrods.
The module you had to work around on your passenger side is the Performance Control Module.
I suspected that was the case. For some reason I thought it was on the driver's side.
But I guess in hindsight, I don't remember seeing a module when I had the driver's side fender off.
Just nitpicking, but it's not called a Performance Control Module, it's called the Powertrain Control Module or sometimes the Engine Control Module (ECM). And the little black box in front of it is the Throttle Actuator Control (TAC) module.
@@dekesone1 That is good info. Thank you!
is it just me or is that the dumbest place to put a computer module?
@kayvonmansouri It kind of feels like it. I think I might relocate the battery to the truck, and then relocate the PCM to the battery compartment.
There are caps inboard that are stapled on and easily removed. Remove those and the flappy doodles on the outside and your engine bay will be successfully vented to the outside for free fiddy.
Sick plate haha
Great video can i ask you what rims are those and the set up u have onyour Z06... im looking to change my current set up form the 18/ 19 set up i currently have on... plus i am looking to do a c 6 brake upgrade and i heard you cant fit them on stock wheel set up...Thank You
It depends on which C6 brake package you're doing, honestly. If it's the Z06 package, then no, those brakes will not clear a stock 17" front.
My very next video is a big brake upgrade, where I talk a lot about brakes, how they work, and why you should or shouldn't do them. So it may have some useful information for you.
I will say, if your car is really just a street car that maybe occasionally does some AutoX or spirited driving, you're better off saving your money.
You'll get more benefit for 30% of the money flushing your brakes, installing steel lines, going to a DOT 4 fluid, and getting better brake pads than spending a whole bunch of money on a C6 kit.
Where did you purchase the vents
Sold out again! I emailed them and they replied they are in stock again, I went back to their site and they are still marked sold out preventing an order from being made. They do not have a telephone number and they say they do not want people emailing them. I'd like to make those fender openings functional but the Knucklheads at Electronsport (what a stupid name for a company that makes parts for combustion engine cars where the electronics have not a dam thing to do with what they are selling). They are so stupid they market parts that are not available. What a way to run a business!
Sounds more like an ungrateful Neil :)
I remain Grateful. I was inpatient wanting it immediately, but they were well worth the wait. The ducts are well made and fit well and look great. Chevrolet should have included this mod because that dummy opening was reminiscent to to the old straight six mustangs that had dummy hood scoops. When a car has something that appears obviously fake, it makes the car look cheap. People notice these functional ducts and most C5 owners want them. They were easy to install and look like the factory installed them. I am extremely satisfied and grateful, although I cannot truthfully say they provide any real benefit other than improving the appearance. I don't race my car, so my brakes don't heat up to the point of needing further cooling. With 40K on the original factory brakes that still have life left, this was cosmetic for me. Seeing a dummy duct opening bothered me. It didn't really matter, but I found it disturbing.@@erikschmidt476
@@GRATEFULNEIL I completely agree!
Electron is for a paint color is electron blue
what tires are you running? and sizes?
That's actually the TAC( throttle actuator control module) definitely don't want to disturb it or it's connections can throw your car into limp mode with zero throttle.
I have screens on the fender openings on mine for looks, but adding a second on the intake (wheel well side) may cut down on rocks and debris a touch. Either way it's a good fix considering the brake ducts are forcefed air.
I had actually considered that. I don't know how I feel about the way that it looks. I was considering putting some satin black wrap on going from the opening of the fender duct to the edge of the fender, (where it meets the door), to try and protect the paint from little rocks that get picked up when the tires are hot.
@@ChaseFarrow If you don't want to change the color, toss a piece of paint protection film on there. It comes in clear (gloss or matte finish) and also in black. It will hold up much better than wrap will to rocks. I have PPF on the front of my Z06. I learned the hard way that rocks won't hold up to rocks very long.
@@BasinMotorsports I actually kind of like the look of the satin. Do you know if you can do PPF film over wrap??
@@ChaseFarrow yes you sure can.
@@BasinMotorsports Hmmm... I guess I have some things to consider lol
What wheels are you running? Sizes?
What if you have the hood track vents on the side and this? Would that make the dirty air worse, better, work the same?
That's actually an excellent question. I kind of mentioned this a little during filming, but ended up cutting it out because it was a bit rambly and I didn't think people would actually care that much lol
Due to the amount of time TrackSpec spent testing their vents, I suspect it would be an even greater improvement to have them in addition to the ducts, simply because it removes another hard surface for the air to collide with before exiting the wheel well.
However, (and I mentioned this in the film I now wish I hadn't cut out), I elected to not do the side-hood-vents because, while I do track this car, it still spends 95% of its life on the road, and I was worried about throwing rocks up through the vents.
Realistically, the vents on the hood would do better for evauting turbulent air caused by the rotation of the wheels, (hence why the AMG One has electronically actuated vents in the same place), whereas these vents will do more for releasing air being piped in by the front brake ducts.
If you're building a dedicated track car, I highly recommend doing both!
I like to buy couple of those air ducts for my C5 Z06 I wondered what can buy from
ElectronSport USA
What wheels are those?
I have these on my 98 C5. The only difference I have noticed since installing them is that extra road grime and dirt gets on my doors. Still like them and think they look good though.
Yeah, unless you're really putting the car through its paces where you're getting your brakes really hot, I don't think you're going to see any difference.
Nice Job - They really should have made that stock unless there's something I'm missing. Given the way GM thinks, it could have been the $5 dollars in plastic they saved.
I purchased these and the template is off. On the lower outside of the vehicle on both sides it will need to be 1/4 up and 3/4 of an inch back towards the center of the car for the correct notching so not create a gap. Found this out the hard way but once you cut your inner well it's too late.
When you said you were missing a bracket. They only sent me two in an envelope and they do not send enough brackets for the installation. One can be used from a pre-existing hole otherwise we should receive 6 for the others, but do not.
I also could not get the inner holes to line up. It's tight enough just with the outer two so I left the inner two out.
Yeah, I noticed that with the template. Unfortunately, I have a little gap on my inner fenders as well :/
That's the engine computer boss.
They always seem to be out of stock haha. Did you just check on the website every now and then to see when they where back in stock? I’m also debating doing the opening where the front plate goes, heard it makes a noticeable difference. You think it’s worth a tenth maybe 2 in the quarter?
It took me about a year to finally get my hands on them because they'd come into stock, and then within a couple of hours would be gone.
Eventually, I started keeping a tab open on my browser, and every morning about 7:30am when I went into my office to start working, I'd refresh the tab until it I finally caught them lol
I managed to pick get them the weekend of Thanksgiving last year, and have been waiting to install them ever since lol
@@ChaseFarrow dang, don’t think I’m that motivated to snag a set. Maybe down the road once she’s sorted out more I might start trying. Gotta torch red Z as well, almost 135k miles, but she’s in the shop at the moment because I did a clutch and rear main on jacks myself and sure enough it’s been leaking ever so slightly. I’ve done all the work on the car myself since owning it so it’s a bummer to not be able to take care of her this time around but hopefully it’ll be fine now, fingers crossed.
@richardelliott8352 There's absolutely no way that the fake vent with a block plate is faster than with it vented.
While it's going to make almost no difference in a straight line, venting the fender allows for a reduction of turbulent air inside of the wheel, which makes for cleaner air around the fender area and better brake cooling.
Whether it be in a straight line or around a track, (especially the latter), venting is going to be faster.
Source: I've never seen a racecar with fake vents.
What is the name of those things that you put in your finders? I've been looking for ever for that.
Fender ducts from Electron Sport USA
I do 180/190 in my 2001 C5 and I have literally never experienced any of the issues you were stating you need these ducts for 🤣
Not really sure which issues you're referring to.
If you're talking about turbulent air inside of wheel-wells, then I don't know what to tell you other than you're wrong, and wind tunnel data proves it.
It's not that you've never experienced it. It's that you've never NOT experienced it. All closed wheel cars are susceptible to trapped/turbulent air inside the wheel-wells.
That's why vented fenders exist in the first place.
After 5 months how are the sides of your C5? Im worried about rock or debris damage as i have been wanting to do this for a long time.
They're perfectly fine.
Honestly, the only thing that concerns me a bit is when I go to the track and the tires get good and sticky. At that point, it might throw some.
If you check out my LS Fest prep video, I wrapped that section before the event just to make sure it would be good.
I have never looked, but I was under the impression that the side vents were functional for exiting hot air from the engine bay?
Not to my knowledge. I can't imagine how they would, especially with the panel that blocks air from escaping out of it.
Youre correct. They vent under hood heat and press This is a bad mod to do.
someone before me must have dumped money into mine b/c mine is a base model with functioning front and rear break ducks
Do you know if anyone has this kit, I have searched far and wide for a set of these vents, please LMK. Thank you.
Unfortunately, the only guys that are going to have them are Electron Sport. They make them in pretty low quantities, so they're really tough to get a hold of.
What heat extractor is that on your hood?
Trackspec
Hey, I inspected my 03 Z06 today and heat DOES exhaust from the engine bay through the side air vents! If I look down through the engine bay toward the side vent on the drivers side, I can see my fingers reaching around the black plastic deflector located in the side vent. The deflector keeps the vent from looking like a hole in the side of the car, but air can still move through and around it.
Hmm. That's interesting. Also, good information! I'm not surprised some air can escape through there, though, it does seem like a horribly inefficiencient method of getting heat out of the engine bay.
I do still believe those vents are better served reducing turbulent air in the wheel wells, but that is still good info, though!
I definitely appreciate the follow-up, though!
@@ChaseFarrow Ya, maybe, but if you think that air is being forced into the engine bay through the front vents by the movement of the car, the air has to move out as well, around the hood gaps and any other openings around the fire wall. The under side is sealed off pretty well, so the air can be forced out the side vents. I’m a retired hvac tech, so I worked with moving air a lot!😀
@@darrylsjodin7184 Air want's to escape through the bonnet since its being forced upward not downward
@@exoticspeedefy7916 Yes, when you’re sitting at a stop light. When on the freeway, air is blowing through the engine compartment at 60 plus mph, so the air is forced out through every vent.
Pretty sure that is your ECM. Also called PCM or PCU. Same smell. Smokin C5 though dude!
You should link where you get the parts from homie 💪
Thanks for stopping by! While I am open about the products that I use, I only link products when I have an agreement with the manufacturer or vendor.
I was impatient. They finally received stock and was able to place and receive my order. It was an easy install and looks great. Does it achieve anything from a functional stand point? Who can tell, but it looks like the way it should have come from the factory. I hate fake scoops and ducts that were put there that are blocked off from functioning making the car look phoney.
I'm with you on the fake ducts. As far as functionality, it depends. If you're using them on an exclusively road-driven car, no. They're not really going to add anything other than a neat aesthetic.
If they're being used on a more track centric car, they are going to help reduce some of that turbulent air inside the wheel wells, cleaning up the air moving along the side of the car at higher speeds.
Yes those vents are functional and the have been since the C3 . They are engine heat vents you know to get the hot air out. They aren't supposed to be areo vents
IF they are, it's incidental. The C5 is famous for running hot and for building high amounts of under-hood pressure at high high speeds.
Either they weren't designed for ventilation, but they just so happened to be a place where some of the pressure can escape,
Or,
They were intended to reduce heat and pressure in the engine bay, and it's just an unbelievably awful design.
Its one or the other. either way, the combination of a hood vent and adding these ducts is objectively better.
Chase, you have a Z06 I have a 2000 Z51 coupe but on your Z your fender opening cover is plastic whereas mine is a soft rubber and is flexible. I'm wondering why mine might be different from yours? Mmmm?
That's a good question. I'm not really sure why yours would be different. Is it shaped the same??
@@ChaseFarrow My bad. They are plastic but both sides are only attached on 1 side so that they can open and close I guess as when pushed on they are flexible. Something worth looking into. At any rate I like your modifications.
@@GregorioLonewolf Oh, gotcha. Yeah, mine could be pushed too. They weren't rigid at all. From what people have been saying, it allows some of the pressure and heat in the engine bay to escape, but it doesn't do a good job of it at all.
@@ChaseFarrow I totally agree about heat dissipation. Enjoy your Z. I just saw on the side bar that a C5 guy in Arizona (goes by My Corvette Life) put up a similar video he calls C5 Functional Side Cove Ducts.
Does it drive any different ? Let say at 70mph highway speed ?
Nah. Realistically, the area where you'll see a difference is on the track. There, you'll mostly see a benefit in brake cooling because the air coming in from the front can more efficiently pass over the hot brakes, and then exit via the fender vents un-impeded.
Technically, it's going to have an impact at any speed. But you're not going to really feel it on the street.
What's wrong with reading the instructions?
I thought that those air extractors were to relive under hood air pressure. Side air extractors were considered functional since the 1982 Trans Am. What about the rear wheels? I suspect a similar issue, perhaps not as significant. I see you have the hood vent to deal with under hood air pressure. This mod should improve brake cooling, have you noticed an improvement?
I have a couple of track days coming up, so I'll definitely be able to answer the brake question soon.
As for the extraction, they may extract some, but they sure as hell don't do anywhere near enough. These things get super floaty over 130 without a hood vent
@@ChaseFarrow yes, i agree about the floatiness above 130, the C7 was much better at higher speeds
@richarddobreny6664 Yeah. They ditched the bottom-breather design and went to a more conventional means of directing airflow. I understand what they were trying to do, but the original bottom-breather design was deeply flawed.
I've had many purists comment on my modifications to the airflow and say "bUt ThE eNgInEeRs DeSiGnEd It LiKe ThAt FoR a ReAsOn."
And they're right. They did design it like that for a reason. It just wasn't a good one lol
Even GMs factory race team knew that it wasn't a good design for performance. That's why the C5.R wasn't a bottom-breather.
How's your paint looking now? I'd imagine there would be some form of sandblasting with such a large opening.
It looks fine, though admittedly, I haven't put many miles on it since installing, plus the roads in my area are extremely clean.
What exhaust do you have? Sounds amazing.
Borla S-Type II
Love it. I have an old Borla on my C5Z as well but yours sounds a little throatier. 4@@ChaseFarrow
@@surgicalmotorsports It might be my headers and X-pipe. Have you done your full exhaust?
Good point. I have full catless X pipe but I don't think they are aftermarket headers. I'll throw on the lift and look. @@ChaseFarrow
@@surgicalmotorsports Yeah, headers make a HUGE difference on these
Have you tested your top end with this? Did it make a difference?
Do you mean top speed?
@@ChaseFarrow yes
@@ericswild I have not. There aren't really many places to do that. I definitely wouldn't attempt it on the street.
Trying to do that while having 2" of ground clearance is a death wish.
@@ChaseFarrowI thought your mod was to decrease the wind resistance from the tire rotation. I was assuming this was to increase top speed. If that wasn't your motivation is it mpg? Brake functionality? Have you noticed any changes in either? Or was there another reason that I am missing?
You have a link to them?
Just search Electron Sport USA Fender Ducts
Where you can you find these?
@@clxbayt5695 ElectronSport produces them.
@@ChaseFarrow thank you, I was looking for them for my 2000 z51 vette
Link?
Hello, and thank you for your comment.
I do not provide links for products unless I have an agreement with the manufacturer.
However, they are pretty easy to find using Google!
Did this improve mpg?
Almost certainly not. But I didn't look. It's a Heads, Cam, Nitrous car with a rather large fuel system. Looking at MPGs would only make me depressed. Lol
I really like the body-colored Z06 side ducts.
I do too, but I'll probably be undoing them... :(
@@ChaseFarrow Really? Why would you do that? Do they chip easily or something?
@@extraplain Unfortunately, they are absolute magnets for rocks. I've had the car going on 4 years, and I've had to have them painted more than once.
I'm about to put side-splitters on, so I might give it one more go with the red in hopes that the side splitters protect them, but I'm leaning towards going back to the factory black.
It really sucks, because I love the way they look color matched.
@@ChaseFarrow Fingers crossed! 🤞
I’m lucky my Z06 is black, so the vents are already body color😀

I wish we had UTEs here in the U.S.
I've always wanted to visit Australia and see the car scene there. Summernats looks crazy fun.
Those vents relieve underhood pressure and heat…. With extractors on the hood youll be fine. A street car really doesnt need this and honestly shouldnt do this.
They don't relieve the pressure or heat even remotely well.
You look like you’re in witness protection.
Pls dont blow my cover
