Re: Spark plugs ???
I hear NGKs are great plugs lots of people run them in their camaros. I have Bosch platnum +4s in mine and I don't mind them at all, lots of people won't run them in their cars. not really sure why.

Re: Spark plugs ???
Well ive heard that you get the best out of AC Delco, NGKs are pretty good but they vary from car to car. I wouldnt use those platinum plugs or iridum or whatever else they have because it doesnt give one big spark but 4 small ones, get these if you want to get a big more MPG but ive heard it kills horsepower a bit.

Re: Spark plugs ???
Bosch = random misfire. They just aren't what they used to be.
NGK, have heard good things as a supplement to OEM. AcDelco =OEM and in my opinion after dealing with these ignition systems for for over well 12 years are the most reliable, for me it's Ac the whole way for every part of the system. |
