Rapidfire?
I have read plenty of do's and don't on plug replacement? Sainthood possibly!!! I have also read what is the best plug for the job. I have a '91 and I am in the same boat others are in on what plug to go with. The Rapidfire seems to be the best option. But the question is, what number, 2 or 5?

Looking up your model year on the above link shows that a Rapidfire #5 is specified, gapped @ 0.045

Rapid fires a good plug but check them before you leave the parts store.Delco made 2 versions with blue print and Champion made anothe for them with green print. All 3 plugs carry the same part number but have 3 differant elctrode designs I have actually found all 3 styles in a box of 8 packed together.
