Thanks for the info. I was wondering what plug to go with and you just helped me out a lot. I always thought E3 plugs were junk to.
Thanks Mr. Cuervo , Iridium have higher melt than platinum this is the only reason why they stay longer , and yes PA plug make more horse power as they dont leave much fuel unburn at the cylinder leading more engine operational rate , i personally use them at my raptor
The Cr9ekpa plug would also be one step colder from cr8ek. That’s why it would also help with the heat and detonation at high rpm. The number (the 8 or the 9) is the heat range of the plug and the higher the number the colder the plug. It sounds backwards and wrong but it’s true. I learned this from working on my turbo Audi TT after I built and tuned I needed colder plugs to deal with the heat and detonation from higher boost. Hope this helps someone.
i just dont call u for advice i follow u as well.lol.much love and respect autta sandiego,ca.
Thanks for the info !
"this is a...terrible plug" I lol'd.
Yeah but the stock groundstrap is where you want it ..you can tell by the pocket in the head the flame is supposed to go up down and towards the cam chain.
So i have to buy the power commander? By the way thankx for your videos they really help us out.
Very cool info 👍🏻
thx 4 info
NGK CR9EKPA you can get from O’Reilly auto parts as NGK 7785, that’s the part number that matches the plug
I dont mean to be so offtopic but does anybody know of a trick to log back into an instagram account..?
I was dumb forgot my account password. I appreciate any help you can give me
@Curtis Julian instablaster :)
@Darwin Zayd Thanks so much for your reply. I got to the site thru google and I'm in the hacking process atm.
Takes quite some time so I will reply here later with my results.
@Darwin Zayd It worked and I now got access to my account again. I am so happy!
Thanks so much you saved my ass :D
@Curtis Julian you are welcome =)
What about the ngk spark plug boot??? I heard that small upgrade gets you better throttle response/ a little more power???
worth upgrading ported/built YFZ450R with MSD blaster to CR8EK? raised rev limit to 11k, ported for top end power, I like to rev.
Hey Cuervo, I have a 2006 raptor 700 that I bought built with lots of upgrades.
Stage 3 hot cams
High compression piston
+1 valves
Pro design intake
DMC dual exhaust
Dynatek coil
Power commander 5
I wanted to know what would be the best plug to run in my setup. Also looking to get more hp out of it so if you have any advice I would really appreciate it.
Whats the best plug? For some reason video isnt working for me just lmy luck
How are you sir I have a 08 raptor 700 that I bought used about 4 month ago I have use it several times and also did some maintenance like engine oil and spark plugs but I start today and is backfiring a lot when is accelerated I. Neutral turn off and when running feel like is about to stalled. Any idea what could be.
Thanks in advance for your help
I ran into a issue with my raptor 700 while riding it died on me a couple of times but for the third time I was not able to fire it up after a couple of hours it fired right up what could the problem be
I have a stock 06 raptor 700 I have a slip on big gun exhaust and k and n filter and a dobek controller I was wondering what is the best gas I should run my quad on I run it on 87 just wondering if I should go up in octane. Im also trying to make my quad little lighter and making a black and red theme dominant black just wondering what I could do to make it lighter and faster and make it look sick. is there anything I can do ?
If I run a 20 shot of nitrous what’s the best plug that I should run
So CR8EK is beneficial on a stock machine ? Or im better to stay with the OEM plug.
If I have 11.1 click piston what plug should I do?
Which plug do you recommend for a 2010 rmz 450 dirtbike? Built close to stock
Will the CR8EK fit a 14 yfz R?
Cuervo
I have a 2019 raptor 700 I do ride it kinda hard some times I race and ride on trails u think I should change the original spark plug to a cr8 I have like i basic some basic upgrades for power nothing crazy
Thoughts on the CR8EIX?
I have 2007 raptor 700 are big bore 734 with kn open box full exhaust with Lex programmer stock intake IM running cr8 stock what would u recommend..plug is getting Lil to much fuel IM gonna tone down Lex today n plug is black when its pulled i run fan off switch while running n my hot light is coming on after a while isn't affecting performance quad is running like a beast should I go colder cr9 ekpa or the ekpa 8 any help would be appreciated Ty in advance
Would be the same with a 660?
I’m using CR9EIX in mine
Really the biggest reason the CR9EKP is making more power then the rest is because the (9) gives the signification its a colder heat range then the (8). With NGK what ever number is in that part number is the heat range,and with a colder plug you can add some more spark,and lean the AFRS a touch to get more power,and still keep knock under control. The CR8 plugs are a hotter heat range,and you will have to richen the mixture to keep exhaust temps under control since you will have to run the timing a bit more retarted making exhaust temps higher. Now as for the dual ground straps being beneficial I dont know,and think this is debatable
That is not why. When we tested it was staying in the same heat range. 8 vs 8 or 9 vs 9. But yes heat range will affect as you stated giving the engine need 1 or the other it will have some variations
Really!! Thats very interesting. Man you being able to do a actual testing on the dyno is awesome!im gonna give that cr9ekp a try this coming up season.
@@jackdaniels5205 yeah, it more about an open initial spark kernal then anything else. initial testing was started in testing plugs in this head in clocking which showed gains and way more gains with the open design
So are the ground straps on these plugs clocked to the threads? So they always end up turned the same way when tightened?
U can clock them if u get enough plugs to try or stack gaskets
2014 raptor 700 bone stock should I just keep running the oem plug? would I see that 1hp you were talking about if I run the better plug, the ek you were talking about.
Yea run stock plug i do!
Hey Mrcuervo i just finished my rebuild 2014 yamaha raptor i did a top and bottom build 105 after the bike warms up it shuts off checked valve clearance is good the piston rings gap is at .016. Plz help me out.
Needs to be tuned if you changed to 105mm piston
I have an 07 raptor with barker dual exhaust cfm performance intake without the lid... and power commander 5 what would be the best one u recommend to run... I'm running the stock plug in it now..
The cr8ek or cr8ekpa
I got an interesting question. I just changed spark plug to a CR8EKPA from stock spark plug from my 2009 Raptor 700 and I’ve been getting weird burning smells coming from my exhaust. What could it be and should I be concerned?
Also my new spark plug is laser platinum
Tune will not change or not change enough to matter. Check for aomething contacting the pipe
I’m running a current map by you on my 18, monster exhaust, PCV, & FCI, would I need a remap if I run the cr8ekpa plug?
No
Would that CR9EKPA plug be a good one to run in a 2011 Raptor 700R.
Rewatch video things got confusing for me as well lol 😆 Keep a fresh OEM plug in it i say. Keep air filter clean is better I say. Maxima pro plus engine oil!
I was running the CR8EK but my local shop didn’t have it and suggested the CR10EK said it was a little hotter. Anyone have input on this plug?
They are wrong as that is 2 steps colder than the stock plug.
So I have a 2019 700r, big3 (rossier, fci, pcv running one of your maps and pop stop kits) was running an cr9ekpa after watching this video. About 10ish hours and the plug died on me, no spark. Put the stock cr8e plug back in, rode all day no issues. Fired the quad up to put it in the garage, sputtered and died on me again. Bike seems to be running a little rich. Would I be better of running a cr8ekpa? Or even dropping to a cr7 plug? Haven't had any issues until now, but now I can't seem to keep a plug in it.
Stock motor should be running the 8* heat range plug as the 9 is too cold and will foul out. , 7 is much too hot and will tend to over heat .
@@MrCuervoRacing thank you! Will get ahold of some 8s and hope that fixes the issue!
Where do i go to get a good spark plug the motor cycle dealer ?? And i got a 2008 raptor 700 with the stock spark plug and are all raptor years different ??
06-19 is the same
Hi, many thanks for the video, i been using the EIX for years no prob but i want to give it a try to the EKPA, now my question is, if the quad (yfz450r) came with CR8E, i have to use the CR8EKPA but you are showing a CR9EKPA (Colder plug), why are you using a 9 grade? Thanks again!
it was just what i had available, if the motor is stock or lightly modified then continue to use the 8 heat range. many motor we build that are highly modified use the 9 heat range
Thanks!
Hi Daniel. Im keen to try one of those cr8ekpa plugs.....they be ok for 15 700 big 3, stock motor? Great vids.....thanks 👌
Yes perfect
Where did you find the cr8ekpa plug ????? I

What is the best spark plug for yamaha raptor 700
I have a 2015 raptor that I trail ride with, nothing crazy very seldom get out of 2nd or 3rd gear and I keep the rpm low. Some trails are creeper trails 1st gear only. Would a different spark plug be better for my slower easier ride style
id run the cr8ek
@@MrCuervoRacing thank you I’ll be put the ais back on to see if the excessive heat from the exhaust pipe still occurs
@@MrCuervoRacing question- I need to replace my ignition coil and spark plug boot. It comes in two different pieces how does the boot attach to the ignition wire?
@@MrCuervoRacing what if I have an 11.1 piston and stage 3 cam ?
What type of wrench are you using?
Milwaukee m12 2453-20 impact driver
Is the Cr9ekpa good for a 07 yfz 450?
Ever figure it out? I'm wondering the same thing...
Do the spark plugs have to be gapped? I just installed a cr8ek and need to know if I have to gap them?
No need to gap these.
Would those last two plugs work in a 09 rhino 700 ??
If the Factory plug is a cr8e then yes. There was one year rhino or grizzly head that had a smaller plug but i dont remember which year
The rhino 700 plug is a cpr7ea-9
@@Chad330r you will have to search and reference an equivalent for it
The e3 works awesome in my raptor 700. You need to test the plug again. I think you messed up
ive tested it in multiple machines, it runs fine But will affect power output negatively. So no I didn't mess up
Lmao… e3 sucks. Had a RMZ450 not wanting to start after kicking it over for literally 2 months. After work and school I would go try it out. No luck. When I noticed the plug said E3 I was like they put a lawn mower spark plug in a high performance machine… put a freakin NGK and bam! Started after only 2 kicks. EFI bike so it had fuel pressure but no damn spark. Complete garbage. When I see E3 spark plug hanging on the shelf I tell them how it is… “they stay belonging there” get an NGK. Lol
Can a cr9eix work on a 700?
i just ordered one for my 2022 Raptor 700 . hopefully all is well, stock machine with gytr air filter & ais delete along with the early on radiator fan kit.
E3 plugs are awesome in 2 strokes and that's it. Lol
You are full of crap. That spark will ignite the gas whether it's sheltered or not. As long as it's sparking on time it's burning the gas. The only difference in spark plugs in 4 stroke engines is whether it's gonna last or not. There's nothing wrong with e3.
Prove me wrong, make a video of each plug on dino. I bet you won't see any difference.
your a fool
