I've got a OTS tune (so take this with a grain of salt) and APR coils with Ruths. No misfiring whatsoever.
if you're ok with conventional wisdom, it's that aftermarket coils are snake oil at best. the only thing they can do is let you run a larger plug gap for better mileage. they don't add power unless they're being compared to some old trashed units.No, there were zero indications his stock coils were bad. That's why I'm asking the questions. You seem very sure that the only explanation is that the coils he took out were old/going bad, so I'm trying to understand more... To be clear: I don't expect APR coils to make 10hp. But I don't know enough to have a strong opinion either way, so I'm trying to reconcile the dyno results.
They're not maintenance items. The conventional wisdom in the community and from VAG techs is you only need to replace them if there's a problem.
The problem is we don't have evidence the old units were old/trashed, and we have dyno results showing more power after the aftermarket coils were put in. Absent other information, at best, it's inconclusive IMHO. I don't think this should upset the conventional wisdom, but it's worth noting.if you're ok with conventional wisdom, it's that aftermarket coils are snake oil at best. the only thing they can do is let you run a larger plug gap for better mileage. they don't add power unless they're being compared to some old trashed units.
They definitely don't last forever, no. The only experience I have with a misfire was on my MKV GTI. Ended up being the coil pack on cylinder 3. The car was 9 years old and had about 135k miles on the factory coil packs. So, mileage does vary pretty greatly.Working through a misfire issue, though new colder plugs probably resolved it. I think ive just read in the past OEM packs don't last forever therefore I might buy new for preventative maintinance at the very least.
Yeah! TDI SWAP!I did the big brain thing and went with the coil pack delete.
But if we do that we'll lose 25hp because we can't use the EQT grounding kitI did the big brain thing and went with the coil pack delete.
Who says u can't use the grounding kit without coils? Spark plug delete too to avoid blowing up your motorBut if we do that we'll lose 25hp because we can't use the EQT grounding kit
You're also not pushing 31-33lbs of boostI've got a OTS tune (so take this with a grain of salt) and APR coils with Ruths. No misfiring whatsoever.
I am and I run Ruths.You're also not pushing 31-33lbs of boost
yeeeeeI am and I run Ruths.
