I went to W24-densos' .32gap... Immed., noticed more performance/boost-top end.
No huge noticeable change, other than what you would expect puting in brand new plugs. My old 7's had maybe 2000 miles on them and didn't look too far off on the heat range (what I really need is about a 7 1/2 heat rating), but opted to go on the colder side since I'm also running significantly more ignition timing.
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
