What about Motorcraft AGSF32PM?

 

I have NGK Iridiums, part #942664 or maybe thats the wrong number and its #7164... not sure. anyways do you know the heat range?

 

great info, you just saved me a few hours of web surfing so i can tell those dumb-dumbs at autozone what i want. they keep trying to get me to buy iridium plugs, they were crap in my engine.

 

2006, LOL. Still good info, though.

 

Ever notice how we always get on someone's case for not using Search, and then when they do we get on their case again.

I'm as guilty as anyone else, basic human nature I guess...

 

Yes, I think this should be a sticky for the tech section anyway.

 

Haha yeah just saw the date! Agreed should be a sticky in the tech section. but i am sorry for using the search button, I promise I wont do it again

 

Hold your Horses Jr... You'll use the search function and like it! LOL

It took Sooooo long to get that thing working again. I want more outdated threads with relevance to start popping up.

 

I used it the other night looking for Innovate OT-1 experiences and found none--I wanted to commiserate with others that may have bought this POS...
