Rev IgnitionHigh Performance Ignition Coil Set of 8 compatible with GM Round Style 12573190 4.8, 5.3, 6.0, 6.2, 7.0 V8 2005-2015

While 2013 Chevy Silverado 2500HD LT can be a monumental pain in your #$% when it comes to using NON-AC Delco parts these actually work and saved me more than 50% over AC Delco.

I’m not Samantha I’m her husband. Just as good of quality if not better than OEM. High mileage 2012 GMC Sierra 1500 5.3L LC9 idles and drives so much better after using these to replace tired old coils. I’ve had them installed for around 3 weeks so can’t speak of longevity but I expect an easy 90K miles out of them.

Works, couldn't notice any difference in performance

Was waiting to put some miles on these, bought back in September now mid January, one coil pack already failed, probably about 7,000 miles on them time will tell

They look awesome and really pop. Work really well too.

They are very good. They burnt out my cheap spark plugs. They are the truth. And causes it to rev harder and faster.

Good price, perfect fit. My H2 no longer downshifts on every small hill.

INSTALLED WORK GOOD SO FAR.
