FAB9 COP kit long term review
 

Hey All,

I've been dealing with a misfire for the past week and think I finally figured it out. I'm thinking it has to do with my FAB9 COPs (see pics). I recently replaced all my spark plugs and the car ran super smooth (like new). A few days later, I started feeling a misfire. I pulled the plugs and inspected them. They all work fine and tell me I'm running a bit rich (Turbo'ed MS3), so that's good. After checking the sparks out, I started looking into my FAB9 COPS and found this.

Now, I'm not 100% sure that the wiring is causing the misfires, but the car starts up fine and hesitates here and there. The misfires are bigger than anything I've experienced (although I may have never felt a misfire before). I'm going to try and find a pigtail to see if I can fix this myself as I'm not sure FAB9 offers any warranty on their parts.

Other than that, I've had them for around 10K in total and haven't had a problem with them. Although I'm not too happy that the wires are already mangled. I installed them as they arrived and haven't done much work with them-- so I haven't really moved them around enough to have the wires split like that.

I'll keep you guys updated on the misfire problem if I can figure it out..

Fix the wires, I can promise your miss will improve.
