.050" or .055" gap for either. Pick the gap you want..

Gap them at .60. You have no mods to be gapped smaller....Plus you're not Force Inducted where the true benefit of colder and smaller gapped plugs are a requirement.

He is though. This is a topic nobody will end out agreeing upon. Someone have some pure facts on this stuff? Information to back up your'* or someone else'* statements?

Not as tight as it looks. You may want to take off the strut bar, but that'* it.

What did you gap the plugs at? How old is your O2 Sensor?

Mine was $20, however since you have a '96, you have a different O2 Sensor than I do, along with more. I'm hoping you don't have 4.. otherwise it shouldn't be that bad. But yeah, around $80 sounds about right for your car.
