Pulled all the plugs today, well 7 of them, the other one was already out... Anyway, I picked up some autolites and noticed that they have more threads. Can I use them or do I need to get the Motorcrafts? I also pulled the injectors and will be replacing all the seals and o rings on them. Oh, and will be putting a new insert for my number 2 plugs, since it ejected itself.

Thanks
Randy

 

the autolites will work fine don't worry about the longer threads.

if you hold them up the MC's you will see that the taper seat is at the exact same length

 

Thanks...
