First, you need to learn to read a spark plug, and a few basics before you "mod" your engine. If you just bolt stuff on and don't know how to tune, you are throwing away money and time.

While I run a CNS and like it a lot better than stock, it alone is not going to give you the performance increase yer prolly hoping for & it can be a finicky pain to dial in for the first time.

For the money, I'd recommend a good expansion chamber exhaust system as yer first "mod" - not only is it the most pronounced improvement over stock, but it's really just a matter of bolting it on & yer done

...well, ya should prolly double check the plug's color, but ya should do that after any alteration
