I recently purchased a set of NGK plugs, but I want to double check the gap specs for my car as well as the wifes car.

Mine is a 1995 Cavalier 2.2 (I read it is 0.060) is that correct?

Other is a 99 Grand Am with the 2.4l in it (same as a z24)

Any help with this is appreciated. And does it make a difference if they are the NGK Platinums? I always assumed the plugs now-a-days were pre-gapped, but it says to set gap on the package.

Thanks guys

I was reading too, that with platinum plugs the gap should be larger then a factory spec? How true is that?

factory spec is with platinum plugs

99 2.4 is either .050 or .060


i know my 97 is .060 , and my 00 is .050

platinums should be .060.....stick with what GM wants them to be at....same in 2.2l and 2.4l

Thanks for the help guys. Turned out they were pre-gapped, package said to gap to specs so I thought I'd check. Plus .... I never noticed that its on the tag on the inside of the engine bay.
