I'm gonna be puting some new plugs in my car soon and I was wondering what you would recommend for gapping these plugs. They are Autolite Platinums and my engine is completely stock... I've heard from .45 to .50 gapping... what do you think

copper plugs (annealed) conduct way way better than platinum. plats are nice for cars that have inaccessable plugs - plats dont experience gap erosion cuz they are hard (and dont conduct very well). think of tires: do you want really hard rubber that does not hold the road (but lasts forever) or some nice grippy skins that hold like on rails, but wear out sooner. i choose the latter.cjman15 said:why are tha copper plugs so much better than platinum
please elaborate. IIRC from high school physics, electricity takes the path of least resistance. one ground strap should do it.Ray III said:Also Bosch's 2 or 4 ground open design makes for cleaner combustion and improved gas mileage, at least in certain engines
