SPARK PLUG GAP

Just wondering what the plug gap on an N/A 03 4.6 would be. Im gonna be gettin some TR 55s soon. Also, if your running boltons like cams and headers if you run the same gap or does it change... Thanks

Keep the stock gap unless you have nitrous or a hotter ignition system.

RE: SPARK PLUG GAP

TR-4 might be a better choice than the 55's. the 55's are a cold plug

Oh I didnt know that. A lot of people say they use the 55s with a fairly stock setup. I will definitely look into those...
