ACDelco GM Original Equipment 12699382 Ignition Coil

This was to replace a defective coil, works as it should and was a direct replacement for the OEM coil.

Coil is good but like the low resistance on the primary coil to put in my Corvette Grand Sport when I believe the OEM specification calls for 0.5-1 ohms of resistance if not the car want run as intended as a high performance otherwise the ECU will not supply the program as designed, without having to change the programming, ALSO IN THE DESCRIPTION THE SPECIFICATION RESISTANCE SHOULD AND MUST BE GIVEN.

Still holding up. No complaints.

Works great in my 2012 Yukon Denali.. OEM. Direct fit, just make sure you have the round ones and not the square ones. Had a rough idle and a slight flutter in rpm's. Pulled the code and has a misfire. I did have 112,xxx miles so it was time. Replaced these OEM coils with OEM ACDelco iridium plugs and ACDelco pro OEM wires. Immediately smoothed out the idle. Freed up some hp and gained almost 2mpg. All done in about and hour and half.

Replacement part for my Chevy #7 spare plug number so far it’s doing okay
