If you need coils, this is a great option. But, there is not going to be a real performance gain over stock if your stock coils are fine. Sorry, but you guys saying the car runs better are Government Exhibit #1 for the effects of placebos.
I specifically mentioned that I wasnāt sure how much was just fresh coil packs, or if there was anything better about the whoosh ones.
That said, my car is a 2016 and the original OEM packs are only 58k miles old, so itās not like they should be shot at this point - coil packs are supposed to last ~100-120k miles before needing replacement
There is definitely a noticable difference I could probably come up with a way to measure it more scientifically if I had the time and motivation for an inexpensive part, that might even show up on a data log.
Honestly I put them in expecting no difference at all, or maybe a smoother idle, but the things Iām noticing are those routine engine behaviors
you just get āused toā and then it surprises you by acting differently, not things Iām actively looking out for. Like the clutch habit going across the dips and speed bumps in my kidās school parking lot that I go across several times a week.
Youāre misusing the much overused āplaceboā, which is something that can be verified to make no difference.
Acoustics, rpm to chugging/stall, etc all changed from swapping coil packs. Again, as long as they hold up longer term, the Whoosh are a good deal being cheaper than OEM replacements. If I happened to have a fresh set of OEM packs (which I donāt) maybe Iād see a difference one way or the other, maybe not.
āStrongerā coil packs arenāt magic, itās just a rewound or slightly different winding ratio, in the same way that rewound alternators and electric motors can be made to put out slightly better current/power. And usually like all aftermarket parts that comes with the tradeoffs where things wear out faster. The OEM pack windings were likely designed with more margin and longer lifetime in mind.
Iām planning to keep the OEM packs around in case the whoosh ones crap out early for some reason.
