spark plugs not fully in?
 

Heyo.. 2 weeks ago I did the ATF treatment to my car.. When i was going and blowing all that crap out (on the OLD plugs), it felt REALLY, REALLY fast..

So i put the new plugs in after it stops smoking and cools down... It just doesn't feel as fast anymore... I was thinking, maybe i just don't have them in far enough, and it's not combusting fully, or something... How far in are they supposed to be?

If you are running the recommened plugs, the BURQ7's and '9s, then you want to put them in all the way. Its impossible to put them in too far.
I usually put a little bit of Never Seize on the threads, turn them in by hand, and then put about 10ft/lbs or so of torque on them.
You don't need them really tight, just pretty snug. the bottom ones go in further than the top. or it might be the otherway around its dark so I can't check mine right now.
anyways, if a little bit of the round part still shows, thats ok.
