- plug wires
- energy spark
So far so good!
I’ve been running these on a 2012 Silverado 5.3. It’s been running great since the change. Been 1,500 miles so far.
Great product.... I can feel the difference from before I had the stock coils.
Coils worked great
I had a great experience with ZZPerformance! Shipping was very fast and package just as good! Fitment and finish was perfect. Coils look great paired up with their plug wires!!
Great parts, as advertised
Fit just like factory parts
