Cheaper than crappy Yellowjackets too!

Genuine? Cheaper than yellow jackets?

http://www.skylinesaustralia.com/forums/topic/187108-jjr-coil-packs-vs-oem-vs-splitfire-vs-other/page-21#entry7236243

Have a search around here, someone did a comparison of fake Nissan coil packs vs. real ones.

FYI, even though my GT-R runs off the factory actuators (so ~12psi), the Yellow Jackets have been working fine for 2+ years, lots of km plus two track days. I run 1.1mm gapped spark plugs.

People had YJ coils fail, people had Splitfire ones fail as well. Plenty of info around here to make up your own mind.

YellowJackets - as good as they sound, as good as their marketing say they are.. they're only good for a stock application.

Once you start ramming in boost they misfire all over the shop.. then you increase dwell (as you do) and they die on you.

In my experience, Splitfires have always been superior even with silly dwell settings.

Exactly, you get what you pay for. But why risk buying ebay "Nissan" coils for $300 when you can get Yellow Jackets with local support/warranty, the seller being an active member on this forum? (that's my point)

Anyway...

That's not even the correct argument. Why risk buying yellow jackets at all, despite the warm fuzzies of forum trader and all that stuff, when they have a higher number of failures than Splitfires and don't save you much money anyway? I'd rather pay the extra and suffer the tiny failure rate of Splitfires than save 30% and near 1 in 3 failure rate that I've seen with yellows.

From my experience, stock application it works fine. So if your car is stock, and you need new coils, would you buy fake OEM coils or yellow jackets (assuming you can't spend more than $500).

Under the artificial limitation that I cannot spend more than $500 I would clean up my existing coils and/or buy some 2nd hand originals until such time as I had the money to buy Splitfires or new genuine coils.

Face it. $500 is co close to the price for Splitfires or genuine that the gap is almost meaningless.

Let's put it another way.....would you buy a known non-genuine Z32 AFM for, let's say, $100, given the knowledge that they do work and have been used by a number of people, or would you rather pay $200 for a known genuine one? The other part of that question is that the known non-genuine ones, whilst they work, don't have the capacity that the proper ones do, and therefore can't be treated as if they actually were a proper Z32 (ie you can't use the Z32 curve in PFC or Nistune). I see the Yellowjackets thing in the same way. They work, but they don't work well enough and reliably enough to justify the relatively small saving in purchase cost.

    • Sorry I haven't been following all the detail, so you may have tried this. Does it idle with the tiniest bit of throttle you can add? You've mentioned the IACV, does it have an AAC valve and have you adjusted it at all (ie, screw the idle adjust screw all the way in, then back it out a couple of turns until idle is stable)?
    • My bad, I unplugged the one underlined in red instead of yellow before. With the car started, after unplugging the IACV (the one underlined in yellow), it idled at around 400/500 for 3 seconds before stalling. Attempting to start the car without the IACV will not start the car.   It does stutter and sputter for around 5 seconds before dying. However, immediately after starting it, you can already hear some slight sputters from the exhaust.   It won't start with the AFM unplugged. If it is when the car has already started, it stalls in a few seconds.   Yesterday, I did take some logs using Nistune of 3 scenarios. Car idling till it stalls Car idling and unplugging the IACV Car idling and removing the AFM I also have some previous logs of when the Car is idling till it stalls and when driving and it cuts. I am not really knowledgeable enough to understand what to look for. After every test, car idles rougher and rougher, until I have to stop. It will be fine the day after.
    • There is no difference between a 17x8 and an 18x8. The total diameter of the tyre needs to remain +/- the same (so you don't mess up the gearing, speedo reading, and clearance when turning front wheels..... so you just need to use a lower profile tyre on th 18 than you do on the 17. /rocket surgery.
    • I thought the same to start with. But then I thought it was one of those LCAs where the end of the ARB goes through a bushing in the LCA itself, instead of having an end link.
    • Yeah - I mean, go the other way. Smaller range. Not larger.
