Review on Standard Motor Products UF271 Ignition by Patrick Hilzer

I installed 8 of these coils on my 5.3 liter Tahoe. I haven't had any issues with misfires or anything, I only replaced them because 7 out of 8 coils on my truck were stock. I am considering ignition coils as a service item and decided it was time. The truck runs great and runs smoother than before. As soon as I took these coils out of the box I could tell they were of high quality. They are made in Poland in case anyone is interested. I did my research and bought these instead of AC Delco coils. I am completely satisfied with this purchase. Quality at the highest level. Especially for money.
