Misfire under heavy load. I did't find out until I was pulling my trailer
they worked great and they looked great
Exact fit. Got rid of miss truck was having.
Lasts about a year much of their products don't last as long bought them and they worked fine but after half a year started to notice sluggish acceleration after the year got a p0300 turns out the coils,fuel injectors and spark plugs all have gone bad not very good products made by them
Install all 8 coils and got better performance and my gas mileage got better
Look good and works great
It's been less than a year and I just had one of the coils go out. I replaced my original coils plugs and wires on a 2002 GMC Sierra with 220,000 miles on it with this set. I didn't notice any difference in performance with the new ones. . It does not give me much confidence in the TRQ brand.
The part was an exact fit and gave my truck noticable power and mileage
Had three or coils go out within months. Had lost quick start up bad fuel Econ. Replaced she fires right up and fuel eco is better than ever
Amazing! I was able to tell the difference in power from my previous ignition coils to these. The price is reasonable. I would order again
This set is intended for models with square shape coils and will not be correct if you have round shape coils, please confirm this information before placing your order.

These will fit a 2003 Chevrolet Tahoe V8 5.3L (8th Vin Digit Z)
I put them on my 2006 Silverado 2500 6.0 with a U VIN
My 2004 Tahoe had a loss of power and the shakes also. I replaced the plugs and wires but was still having an issue and a misfire code. Then after changing the coils it cleared up.
