I was wondering what the stock gm l67's coil pack voltage is? I had some summit racing coil packs on my car, there junk! I had them on there for four months and one went out. So I put my stock one's back on and the car runs better then when they were on there! I was also wondering if anyone make's a good aftermarket coil pack for gm's? Thankyou for your help on this!!
 


Factory GM coils are all you need. They out-perform the aftermarket ones hands down. I have MSD ones, I've never had an issue though...but it sure wasn't worth the $200
