Dont use anything but Moto plugs. Plenty of threads on bad experiences with driveability from Champion and other plug makers.

Part 1 -How to Test the Fuel Injectors (Ford 4.6L, 5.4L)

 

well the mechanic had put 2 champions in there because he said that they were 1 peice design and i woudlnt have to worry about them breaking off again. I will buy the ford ones. but i really didnt want to buy the other 2 because they are brand new. Would it really be that bad to leave thiose 2 in there?

 

send me an email, i will send you pics of the champions i removed, then you can decide

They make 1 piece moto's for the black boots I believe.

 

Well guys I know I said I was going to get on those spark plugs. But I've just been very swamped with work. Haven't had any time to put them in. Now I got a little problem, the expy has been running great since I got back into town. No misfire at all. The problem is that we have a family emergecy out of town about 300 miles away. Am I risking a lot by taking the expy the way it is?

 

ok so i am finally getting able to work on the spark plugs. I removed the coils and turned them all a 1/4 of a turn. I also sprayed some carburator cleaner in them. I am going to let them soak over night. hope i have no problems tomorrow

 

some of them were easier than others to turn. the only ones im worried about are 2 that squeeked loud as i turned them
