Worked great but..?

Coils fit great and worked good after installing only problem was with the plugs , had to cut , modify them so they can connect to the spark plugs , or they would not connect and keep coming out , after that they work great

Ignition coils!!

I wouldn't recommend to purchase coils from here. They were cheap quality and made incorrectly. I was forced to use them because my car needed them and I had to make it work. But the coils kept falling apart on the magnetic side and not only that but they weren't made to fit my car like the car look up said it would fit. Not happy wouldn't recommend

2005 Chevy Silverado

My truck went from having misfire in cylinder 8, then multiple misfires. Codes instantly cleared after installing new coil packs, wires, and spark plugs. Truck still runs strong at 230K. Thank you guys!

As advertised. 1AAuto comes through for me again!

2000 GMC Sierra 1500 LTE 5.3 V8. Products arrived on time, and were as advertised. Installation was occasionally challenging (not unexpectedly) but the parts from 1A Auto were just right. So far so good!

I have a 5.3 vortec motor out of a 2006 1500 chevy truck. Will this kit work?

This kit is correct for the V8 motors out of those vehicles with the square style coils.
