No, Autolite is made by Honeywell, same company that makes Motorcraft. Autolites are fine in a 4.9.

 

Okay, thanks for the help glc.
I just noticed it says senior member under my name
I'm guessing this happens at 100 posts?

 

Yep!

 

GLC COME BACK! haha
I got the notebook off of the original owner of what he has done to the truck ever since 1990. It says he put in a new distributor, cap, rotor and wires 27k miles ago.
Should I still change em?

 

I wouldn't bother if it's running smooth. Pull a plug and look at it before you buy plugs.

It runs great, every once in a blue moon while im just cruising it will shutter, kind of like shut off, maybe even miss i'm not sure, but as soon as I give it a little gas it's fine.
I was going to pull the plugs but not until I have to money to replace them if need be, I don't wanna find something I don't want to see..

 

Thanks ymeski, I'm definitely going to do a little timing bump whenever I take a look at the plugs and such.
