I just bought two Motorcraft DG-511 COP's from Summit racing. I paid $90 for both shipped. But I still have a misfire.

I'm going to change my plugs and install aftermarket COP's (accell brand), since I can get a full 8 pack of them cheaper than buying six additional Motorcraft COPs

Less than 500 miles on them.

Will take $45 shipped for both.

 

Sold..

 

Have you installed the Accels yet? I'm looking at those also and was wondering what you thought of them. I'm thinking of replacing my wires as well.

 

I just got them installed this weekend. So far, I really like them. Truck seems to run much smoother without any misifre under load. Although I did change the plugs at the same time.

No complaints yet, and cheaper than a full set of Motorcraft COPs.
