MChevrolet  Spark plugs - Chevrolet blazer 2000 LT 4.3L AWD
Changing spark plugs?...which one will behave just as OEM?

Not a long ago i wanted to replace spark plugs on my Blazer.I have done a research which spark plugs suppose to be the best ...ACDELCO,NKG,BOSCH,CHAMPION.BRISK....There is many threads that original copper ACDELCO or CHAMPION are the only one which provide the best performance.GM recommends BOSCH also unfortunately they not having any good feedback from GMC/CHEVY users.I decided to follow GM recommendation and went for BOSCH 9601 Iridium performance spark plugs.So far done 2k miles drivedrivedriveand all seems to be running perfect.I havem't noticed any rough idle, misfire or heasation at acceleration.

I would like to share my finding that BOSH 9601 Iridium spark plug will perform great at your chevy.
