Another spark plug thread!!!1!
Any plug but BOScH I ran them in my wrangler and had nothing but problems. The check engine light always came on and when starting sometimes it would back fire threw the throttle body. I like NGK myself
anybody here ever replaced their spark plugs?
The check engine light was always coming on and the code was intermitent misfire. I'am a mechanic for a living and some of my mechanic friends ran into same problem. Since I pulled them out about 4 years ago I have had no problems, plus better power and fuel mileage about 2 miles to a gallon. They where the plat 4s.Really?!? i have ran bosch platinum plus's for 3 years now and i like them a lot... i just got some fresh ones in there today..never had any problems with them either

So I have had the rc12s in for two days now and the 4.6 does not like them--occasionally bucks and last night wouldn't rev past 3K when I got on it(surge)--dunno if I should fool with the gap. Pinging was almost non-existent in the 2.5K-3K area, the area that the rc9s had some during part throttle accel. I should've tried out the NGKs, based on your recs(Wolf and Talyn can be a lil sketchy you know, jk), but had to see the difference b/t the 9s and 12s. Before the 4.6, the 96 4.0 did well with autolite double plats.
