right now on my 93 z I have msd cap,rotor,plug wires and ngk platinum plugs.would I pick up any performance switching my plugs to a different one. they only have about 3000 miles on them.let me know what you think and what you run. thanks,snareman

 

You should tell us more about your car so we can give you better advice. If the car is relatively stock - you will not gain any performance by switching plugs. Plus those plugs you are using are good plugs anyways..

If you had very high compression OR were using a forced induction set-up - then you would want to switch to some colder burning plugs. But if thats not the case - then you should be fine

 

93z,lt1 700 r4, midwest 2800 stall,nittos.no cat 1 le intake bellows,tpi airfoil,lingenfelter cai ,hooker aerochamber with ss tips.msd cap,rotor,wires.bmr str and lcas.rebuilt performance trannywith transgo kit and ls1 tranny mount,b and m 24,000 cooler.just a hair over stock(so far).

 

Well until you go into the motor - or add nitrous or forced induction - then those plugs will be fine. They are darn good plugs anyways!

If you end up doing any of those above stated things - then you will want to switch to a little colder plug to prevent detonation. Such as:

NGK tr6's
Autolite 104's
etc.

but for now, you should be great with those

By the way, you are off to a great start with the mods you have done thus far

 

Nothing wrong with NGK.. they are a very good plug.
