I'm sorry but...
...it's a 3 year old car with about 100k miles. That's worn in... not worn out.
The car was fine... after a plug change it wasn't. The problem was the plugs... not the rest of car.
Thinking you can't go WOT on a 3-4 year old 115k mile car with decent compression and reach full boost is just silly. I'm personally not a fan of Autolites as a cheaper alternative to an OEM NGK-plug... but properly gapped Autolites are better than knock-off ebay plugs. It may be some plug-snobbery on my part... but in looking at reviews, it seems like a lot of folks use Autolites as a non-OEM cheap alternative and leave negative reviews about poor performance... even with claims they were gapped properly. I've never tried buying a 75% cheaper branded plug off ebay... but that sounds like it'd be in the too-good-to-be-true category. For near-stock cars... I'd always go with OEM plugs... but that's me. Still, anything else is introducing a variable that may not work out and require re-work... especially for those of us that will only be changing them every 5-10 years. doing 10-20k miles a year.
@Physical... if it were me, I'd still get a new set of OEM plugs to put in... or at least pull and read those Autolites midway between now and 200k, assuming you're going to keep the car until the next time they're due. Their electrodes erode a little as they're used and gaps will open over time. You can regap it back to min-spec to keep it in spec through the plugs' life if it's going out of spec at the 1/2 way point. If you're gapping on a near-stock car... you always want to gap at min-spec, as they'll open through use. If you gap at max spec... they'll open further and that'll put you out-of-spec during their life.
