I absolutely love these coils. There is definitely a difference in responsiveness on the throttle in all RPM ranges! I feel more power both on top and low end! Definitely pulls a lot stronger on the highway. Also, it got rid of a slight misfire I had at idle. I still have yet to replace the spark plugs with AC-Delco 41-110s but even with the old spark plugs still in there the responsiveness feels great! I purchased these for my 2004 2500HD with a 6.0 gas engine. The coils did not fit directly into the OEM coil bracket but it was no big deal. I ended up grinding off part of the bracket enough for the coil to sit well enough. I was able to only use 1 screw to hold them down, however. I used washers to make them fit snug. I'm sure there are other ways of doing it besides mine. I plan on getting ordering an aftermarket bracket in the future
Terrible. Spend almost $200 on these coils and they cut out worse than oem coils. Would love to send them back but they say in the return policy that electronics are non refundable and if you do send them back they may give you 50% less than ehat they cost back
A MEGA SQUIRT ECM IS BEING USED WITH THESE IGNITERS AND BEING INSTALLED ON A 400 CID SBC. THE GREATEST CHALLENGE IS FABRICATING A BRACKET THAT WILL NOT ITERFERE WITH THE PROFORM VALVE COVERS.
