I drove the car w/the newly installed spark plugs and the car definitely runs a lot better, just real smooth. I know I need to get more miles on the plugs but first impressions are very positive!

Commented on this a few days ago. Mine came in today, the bundle from usp motorsports, and they're the "M"! Will install tomorrow and update with how car is running. I know this may be a stupid question, but the washers that came on each plug stay on there, correct? There are two of them on each plug. Also, you didn't gap them, right? You just threw them right in?

Did not do anything but remove the cardboard and thread them in by hand, then bottomed them with my ratchet.

Wow! I just installed the "M" revisions 10 minutes ago and I can immediately notice a difference. Put everything back together, closed to hood, started her up, and it ran smoother than the first day I got it! Very very well worth the $55!

No problem! I'm just why of 30k so it was a good time to get them.

Would I be correct in saying that in any stock application these are likely a waste of money, or, have guys with stock cars run these with a noticeable improvement? Just curious. Thanks.

They might be too cold so they might foul sooner and get worse mpg

They're for cars running more boost, not stock cars.

Are these plugs recommended for JB4 users? I'm logging peak boost at just under 25psi (24.7psi to be exact) and have additive as much 8psi over stock at the top end with relatively clean logs. Would I benefit from these plugs at all?

Yep I'd get them. The rule of thumb is 1 heat range colder for every 75-100 crank HP added

I'm running them with my JB4 (installed same time as JB4) on Map 2. Runs great.

Thanks, good to know! Buying them straight from Audi of Honolulu so I assume it's pre-gapped and I just swap them out?
