You can never go wrong using AC/Delco.

You find about 3/4 of the people on this board use NGKs

I'd vote for the ngk tr55's as well. I've ran their TR6's and now their TR8's on turbo and nitrous motors.

I used delcos last time I did plugs but have been told by many that the NGKs offer the same if not better performance for less money.

Either way stay away from those junk E3 plugs...when I tried them I didnt expect a power gain but I did expect them to last over 15k miles...I had 3 of them foul by 15k miles and replaced them with autolites because I was in a bind and had to sell the car quick.

autolite. the cheap copper plugs.
i had nothing but trouble with stutters with ngk's. several friends have the same problems.
i read a lot of problems about misfires idle/cruising with these, although they do run fine at WOT.
autolite makes my car drive like a stocker.... (sales pitch)
hehe.
