What are the best spark plugs for my 2000 camaro ???

 

Use the same plugs tha the factory put in the car. Check your owner's manual, or AC Delco 41-101 Iridium

 

what about those NGK iridium 4 spark plugs??? Are they any good?????

 

Nothing wrong with them, but on a stock engine you can't beat the plugs that the factorey put on the car.

 

I've been shopping around for plugs too, and I've been thinking about getting the NGK iridium plugs as well. Pete does have a point about using the same plugs the engine came with from the factory though too. The engineers at GM must know whats best for the car since they designed it and everything.

 

when is the a good time to upgrade the spark plugs, what performance parts do you need to have. i put some bosch platinums in mine.

 

NGK T55's
AC Delco Iridiums

I had some NGK TR6's when I was gonna use nitrous but I never used them, the T55's worked well for me tho

Stay away from bosch and cheapo brands...
