RE: Spark plug question

The plugs given by ford are motocraft plugs and a dealer will actually charge about 10 a plug so 7 a plug is a deal for aftermarket ones. I was lucky, I got denso iridium plugs (13 a plug!) free with my magnapack exhaust. Ahhh the sweet deals of ebay.

I know this will sound dumb but how exactly do i use a spark plug gapper?

you pick your gap and stick it between the pole kinda think on the spark plug (srry im not a plug expert) and it would spread out from doin that. but thats how i used to do it... i have changed plugs in a long time
