Found a great video on doing this job. Not obvious for the first timer like me since I haven't done this on this car yet, but once you've seen it, you wonder how you didn't figure it out sooner. My issue was #5 is pulling timing about 10 degrees compared to the other 5 under hard acceleration, with or without a tune, its just more obvious with the tune. I'm replacing plugs since it has 83K miles and who knows if these are original., and swapping coil packs with #1 to see if it clears up or moves to #1, once the snow melts since #1 is super easy to get to if it is the coil pack..

Got my thin-wall socket from Autozone, just waiting for the snow to melt and have some time to do this.

I first tried the 97506 on their stock gap (~.03) and got some misfires and went into limp mode. I re-gapped to ~.023 and now seems to be running smooth, but my logs still aren't as clean as before the new plugs. If I were to do it all over again I'd just go with stock bosch plugs, they're plenty fine up to anything on stock turbo. |

NGK 97506 gapped down to 0.022" Caution that there have been reports of counterfeit NGKs floating around the market. They look fine, but run poorly. I'd only buy them from a reliable vendor such as Burger Tuning or FCP Euro. Expect $14-$16/plug shipped. |
