Great job and being very clear! I agree and don't forget to mention that OEM coil packs are more expensive than the Z1 coil packs. So like you said, if your in there anyways, have to do them, than you might as well get the upgrade and do it cheaper than going OEM.
My Z is tuned and is hitting 60K miles and I've noticed a decrease in gas mileage and poorer off the line throttle response, so I'm going to replace the plugs and coil packs do a manual cleaning of the throttle bodies and spray clean the MAF sensors. I'm curious to see what the plugs look like and how much the gaps have widened. I think that with the gaps widening and the firing voltage increasing, the coil packs are probably under greater electrical and thermal stress than when the engine was new and so they might be getting a little ragged by now.
I changed my spark plugs, coils packs, and did my throttle body clean at 51k miles. I' currently at 90k miles. I'm not going to replace them until 101K miles and when I do I'll try the Z1 coil packs. I trust Z1, and the stealership for parts lol.
Damn my 09 is 104k miles and I've never done any of those things. I did just buy these plugs and coils though. Suppose I'll clean the TB while I'm in there too. I've only had the car since it had 70k miles but it's been idling kinda rough lately and threw a p0300 code, random misfire
@@thatdallastx7861 car was solid as hell after changing the plugs and coils, I highly recommend it. But then I did some more mods and got it dyno tuned and now it throws codes (p0300) again lol. Car makes 332whp on stock cats/headers though haha. I had the Z1 carbon fiber intake installed and their ported intake plenum. Car already had AAM S-Line catback exhaust. Z1 installed the intake and manifold and then tuned the car with ecutek. Car runs amazing and is truly quick, but it'll throw p0300 especially in cooler weather.
Good show bud.. Appreciate ya diggin into the myth of power gains from this "upgrade".. While it definitely helps the engine operate more efficiently, easier; it doesn't give extra power by themselves.. The power source/supply to the coils needs to be increased. 12v is 12v, and most operate on a 5v reference anyway (which is computer controlled/limited); no matter what coil or plug you use. I would consider these when time comes for replacements.. Not too far off oem part prices. Great show man. Greatly appreciate this series!!! #HustleOn
That doesn't make any sense. You don't need to increase the input voltage. A coil pack steps up voltage by the winding of the coil inside. If the coil winding is different in the coil pack it can make more voltage with the same input voltage and by doing so you should end up with a more efficient burn of fuel and air which in turn could absolutely equate to more power.
@@mikeschaner5853 they do exactly what the z-1 coils do. They step up voltage to create a higher voltage spark by way of internal windings. They still use a 12V input. Am I missing something?
Excellent vid. I have 130k on my G35 with a tune and full bolt-ons coming up in a couple of months. Just purchased these coil packs and will have them installed next week. I most likely have the original packs still so this was really a no-brainer
Thanks for doing these reviews on items like this that we're likely to be considering for our cars. I agree that unless you're going to forced induction, or the OEM coil packs are failing, then getting these is probably a waste of money. A better expenditure of money to restore some lost pep in your VQ37 might be a new set of iridium spark plugs if you're pushing high mileage on the ones in your engine. I noticed that NGK and Denso have competing designs and so there might be something new from these guys that might work well in the VQ.
i like Z1 products but some of their products are not so great, these coil packs i have been thinking cuz my car is almost 120k miles and never changed it but i believe it should be last the thing on your list of mods,
I think in order for Z1 to sells these they would need to show stock readings from the factory Hitachi coils and the "Z1" coils. A brand new Hitachi coil is 53$ on rockauto plus 5% off. make me change my mind Z1, show them readings
I have a g37 coupe im not tuned or anything I jus have small thing like headers,test pipes,muffler and cat delete and long tube intakes it has 130k do u think I should be getting the z1 or oem thoughts?
Off subject with this vid but do you have a heat exchanger Installed? I was told our non turbos can’t/ don’t need it even with a tune? Asking because I’m about to tune mine.
Hey boss your very knowledgeable so maybe you would know the problem with my G. While I’m driving her around back ways she does awesome runs great, when I enter on the freeway and go she still runs great but every single time I’m going a longer distance I always seem to go into “limp mode” it’ll slow down and will not let me go past 2 gear if I try I’ll begin to bog and start backfiring so I have to pull over and turn her off and on and she’ll do completely fine. It doesn’t give out any codes what so ever to a reader I’ve changed my camshaft sensors, maf and no luck also took it to my local mechanic and no luck. Also tested my sensors and fuses.
Sounds like ur transmission bro. Had the same issue car running great but when I go more then 20miles I loose 3rd 4th gear. I let it cool off about 15 min and then it's fine again. Get it looked at b4 it's too late
Nice vedio bro, have you tryed the z1 coil packs as yet or know of any one who have tryed the z1 coil packs, and give their personal opinion on them . I was thinking about getting those, my g 37 has 98000 miles .
Hey man. just got my Borla ProXS and FlowFX resonators installed and loved it. But its week later and today the exhaust doesnt sound the same. Has this kind of vibration at around 2500 and then again at 3500 and it sounds like there is a tad of rasp. My pops also sound different. Is this normal? Is there like a break in period that I just completed or is it possible I blew something up?
@@SpeedCultureStudios could I send you a video of it on Instagram? I’ve reached under and smacked the x pipe and the resonators with my hands to here if they rattle and I don’t hear anything
My oem ones just gave out , so are these worth getting or should i just spend more to get the oem ones which cost more for the same gain? Let me know guys need help :)
Having any luck with the Z1s? I’m throwing a code on my #4 cyl and I want to replace all my coils and plugs… should I buy these in your opinion? Thanks
I’m just not a fan of Z1 in general. Their parts are just lower quality than other manufacturers (but cheaper, so I get it). My biggest issue with them is their service. I’ve been modding my car for the past 6 months (about $8k in parts) and they have been a nightmare. Poor communication, poor tracking, no updates on timelines for parts delivery, didn’t want to take back parts that dont fit, sell parts they don’t have, etc. Do yourself a favor, upgrade to better parts (White Line, SPL, even Megan and Stillen are better), and purchase direct from the manufacturer, don’t go through Z1. You’ll get the parts faster, have better comms/tracking, and get better service.
@@SpeedCultureStudios You’re lucky. And maybe you have a different expectation. If I buy something, I expect to get notifications for everything (purchase, shipped, shipping updates, delivery, delays). I also expect that if an item is not in stock, it is clearly stated (along with anticipated re-stock date). I don’t appreciate being sold thousands of dollars of parts, only for the confirmation to notify me that the part is unavailable, and will be shipped in 4-6 weeks. This might be standard in the car parts world, but I’m new to modding. If you went into a Footlocker and bought a pair of shoes, and then they hand you a receipt stating the shoes would arrive in 6 weeks, you’d be pissed.
@@jdstarek no I think expectations are the same. I’ve just always received anything I’ve ordered by the next day or 2. I’ve ordered very few z1 branded items so I can’t speak to quality, but service has always been good.
Generally have had good service from them, but I asked them how the got the Monterey Blue I requested on a part they powder coated and they were totally useless and didn't even read what I said. They replied to a question I didn't as and I had to ask again and again and they never really gave me an answer. They just said they don't know. How do you not know if you're the one who did it?!?!!?
It’s the same for me I had a really good experience with my tomei from z1 but everything I bought after that my experience with them just went downhill. Their customer service is so poor and they won’t take any parts that I bought that didn’t fit among many more problems they didn’t feel like solving.

I’m sure you’ll notice a difference with fresh plugs and coils!
