+1basically 99.9% of the crap you see advertised for plugs is all BS. Go with a good reliable brand (OEM Ford for example).
You get nothing for upgrading to the super expensive ones. If you go with copper you just have to change more regularly. The most important thing here is to check their gap, thats mostly it. Dont believe the hype.... I am running Iridium as thats what came in mine and I can run a larger gap with my supercharger setup, but many run copper in mine 100% fine. I just dont like to change mine yearly. For yours with copper you should be fine for a LONG time.
I do ^this. I also put dielectric grease on the spring thingy inside the COP boot that connects to the spark plug.also be sure not to tq them down to tight, you dont want to mess up the threads, also antiseeze should be used (dont go crazy with it)
Why do you have to take the tire off?!?!its about time for me to inspect mine.... always fun taking the tire off to check your spark plugs....
ever seen the engine bay of a 4v? lets just say it's not fun to work onWhy do you have to take the tire off?!?!
Spark plugs are a breeze on the Mach 1. All you need to do is remove the cold air intake so you can get to the passenger side.ever seen the engine bay of a 4v? lets just say it's not fun to work on
