Auto Lite, however I will probably change these out around 25-30k with the E 3

 

Be careful with the e3 plugs, I've read here about the electrode straps frying off.

 

That was on an older 2v, Stealth. We only have one report of them in a 3v, and so far so good, but with very limited use so far.

Supposedly the Autolite 2 piece plugs for the 3v are the same as the Motorcrafts, unlike the ones for the 2v.

 

I would have went with the champion which is a one piece I think, but when i hear champion I think of a good lawn mower or weed eater plug....

 

True about the e3, but I'd still give them some time in someone else's truck before I put them in 3v.
