Ok guys I have a 2000 camaro ss A4 and I was wondering if changing the sparks plugs to NGK's is really worth it? I hear everybody saying that they have them but they haven't said if they improved anything. I now they supposedly improve spark but do they increase anything else.

 

I was thinking the same thing, then I asked my mechanic who's a GM Master Tech. and recommended I use nothing except the factory Delco Platinums. He says they're very good. I just bought them yesterday and the MSD wires will come tomorrow.

 

I never noticed anything after switching. It's basically just an insurance thing. You never know when you're spark plugs are going to crap out (always at high RPM, when you need them most) The only time you REALLY need NGK's is when doing nitrous or forced induction, and you running a colder plug, too.
