GMS coils

Fepony · 01-02-2008, 10:26 AM

Beware...they are crap. A total waste of money. Stick with the stock cops. I got my new motor in and ready to tune and the coils were causing a misfire. At first we thought it was spark blowout because the coils were new. We pulled the plugs and regapped them all only to find out the gaps were right so we changed to a colder plug. Replaced them after repairing 2 coils that came apart and tried again. Same thing. We spent another 2 hours changing the coils back to stock. When pulling the GMS coils off, 3 came apart and 2 had cracked. We put stock coils on and made 580/642.

These coils are crap. The assembly is crap. The total cost of installing these was over $1k ( coils, removal, reinstall and removal) and i still run my stock coils.

I never had any issues with mine and I ran them for quite a while. That being said, I won't be running them when I get my truck back from ATS.

Is there a place online you can order new Ford COP's? (Complete assembly boot, springs... etc)

I have seen a few vehicle come in here with the GMS coils missfiring. Just not as good quality as the OE stuff
