JJR Coil Packs Vs Oem Vs Splitfire Vs Other

[MikeRWK]

Some of the holes on the yellow jackets have epoxy or something in them i took a philips head screwdriver and scraped it out, coils fit perfect.

orderd some yellow jackets today. Paul is a champ, emailed me back pretty much instantly to confirm my order. wish he was still a trader on here.

I've fitted a set of Yellow Jackets the other day along with new spark plugs aswell gapped to 0.8mm and took it for a 'hills test' - and my god, the car drives absolutely beautiful, very smooth, straight to redline no hesitation no nothing, feels like a whole different car! I cant remember the last time the car has driven this well!

+1

same result, put mine in yesterday. couldn't be more happier!

[heller44]

I dropped mine in with a replacement harness and new plugs gapped at 1.1, not missing any more and feels to have a meatier mid range, but probably just my imagination.

Why is everyone going straight for a closer gap?

[Birds]

There seems to be a bit of a consensus that anything above 0.8mm can result in misfire. I'm gapped at 1.1mm with no misfires, but I guess if it's solved peoples problems then we can't question it

I say leave it at 1.1mm and if you start to develop misfire then re-gap.

Put my yellow jackets in today. The difference is incredible. Missfire is gone and response has improved qutie alot. These coils are worth every cent!

[flyz33]

apart from ebay, is there anywhere else i can order the yellow jacket coil packs?

Thanks guys

You shoudn't have to gap the plugs down.

Cheers

I left mine gapped at 1.1mm also. Just new coilpacks fixed my missfiring. IMO if you need to gap down your plugs your ignition system isn't up to scratch.

Smaller gap = Weaker spark

Larger gap = Stronger spark

This man he knows^...

i went the already gapped iridiums at 0.86. Since JJR replaced my faulty coil pack it hasnt missed a beat.

[typevu]

I was thinking whether I should leave them at 1.1 or go down to 0.8 but then thought didnt want to risk any missfiring and having to take things apart again - it gets tiring mucking around with the same thing over and over again... but it drives perfectly now no problems whatsoever so its all good either way. I'll probably give 1.1 a go next time see how that goes anyway.

i fitted my yellow jackets the other day. it was time for new plugs, so i swapped out my 0.8mm coppers for a new set of 1.1mm.

13psi, no missfire, at all, at 1.1mm!!! my old coilpacks had no missfire either, but needed 0.8mm to get that result.

for the price, you cant go wrong. and Paul from performance-wise is a top bloke to deal with. very pleased all round.

on a side note. my logic says if you can run 1.1mm without missfire, then you'll have a bigger bang, better burn, and optimal conditions.

yet i have heard many people say if you are running higher than standard boost, you need to run 0.8mm, regardless.

why? i just dont get it.

just ordered the Yellow Jackets. Cant wait for them to arrive.

I did the DIY to my oem coils (wrapped and silicon the coils) and replaced the plugs with NGK copper V power Heat range 7 and re gaped to 0.8. The car was still miss firing at 5k RPM and wouldnt let the car boost over 0.6BAR

I have HKS2530's with the actuators set to 1.5Bar.

I'm going to try and just drop the yellow jackets in with the spark plugs i have now with the 0.8 gap and see how it runs, if not then I will buy some plugs with a 1.1 gap....

[SkyHi_33]

ill be re-gaping my plugs back up to 1.1 before the next track day practice a fortnight away. will see how it goes with a bit of thrashing

I made this argument a couple of years ago in one of the spark plug threads. No one listened to me

My NGK Iridiums are coming up onto 60thou kms and still running strong and good condition after recent inspection. Stuff coppers, I'm not into changing every 10thousand

[heller44]

If I was running iridiums, I'd be needing to change them every ~10thou same as the coppers.. Fk that.

[Munkyb0y]

to be honest, i like changing my plugs every 10k kms. lol

gives you the opportunity to check their condition, spot any warning signs, and give the whole area a once over.

i'd feel weird not looking at them for 100k kms, if they infact would even last that long.

[Newy]

bit more feed back for superspark. Had mine in for about 5000kms , including 1 track day. plugs gapped at 1.1mm. havent had any hint of even a slight misfire! product fitted exactly as per the oem items.

I'm yet to increase boost up yet, will post once i have.

ALSO 12 month warrenty on super spark... not 2-6months as previously stated.
