Stock gap on those is .028 I believe. My car backfired and didn't like it at all. So I took them out and widened it to .030 and that did the trick. Idle was smooth and it ran extremely well.

thank you, yeah those bosch plat 4's are giving me nasty misses at high rpms, and some back fires.

I left mine at .028" (stock) and they work good. If you do regap them, do it very carefully.... that tiny electrode looks like it would be easy to break off.
