First, what type of spark plugs would you recomend for a NA, do they really help on performance much? Same about plug wires? Batteries, do those help the engine performance (messing around with different batteries)? And is the K&N High Air Intake system any good.

Thanks, Justin

PS. I fixed the dang engine light, just had to reset it

I use ngk plugs and magnacore wires w/ a crane cams coil. Ididn't really notice a difference till i put the coil in. Ialso have the fipk kit and i did notice a difference w/ just the filter. but i a noticed a bigger difference w/ a custom cold air pipe and it isn't that difficult to have one made.
