Default Spark Plugs

what kind to use on my '00 T/A ? would stock ones be fine? and what gap? I'm slightly modded, thats why I ask. K&N, Kooks LT, SLP Loudmouth, Edlebrock TB. What would be great for this set-up?

Also next weekend I am checking out my pushrods, while I was in there I was wondering a good size for new rockers. (other than stock) to safely give some HP or even just run smoother.

TR55s are a good replacement for stock plugs. The stock gap is at .060"


I wouldn't waste the money on a set of aftermarket rockers, the $300+ can be spent else where(i.e. a LS6 intake)

NGK sounds good. it what I run on my Grand Prix.

lol as soon as I made the post I checked on some RR's and see the prices are about the same for a cam. lmao, was hoping to find some better prices. but for now, i'm leaving that alone. atleast til the cashflow is right for the cam and tune
