So far so good, gmc with 4.8 runs much better but had bad stock plug wires, so cured my misfire. As far as performance, seems a little better but I still have other upgrades to perform including exhaust and tuner to hopefully wake it up a bit and improve mpg

I have been having engine trouble and poor gas mileage since I bought my truck. A coil went bad and I decided to upgrade my ignition components. This kit was perfect. The engine runs smoother and fuel economy improved. A can of Seafoam in the gas tank help clean the injectors. Only wish the kit came in other colors than red, but it still looks and works great

Everything came nicely packed, received everything that was included

Works as it should great price compared to buying stock replacements i would recomend

I bought because I was replacing a collapsed lifter and thought why not replace everything along the way. Put it all back together and engine runs like crap. After a lot of diagnostics, traced problem to 2 bad coils and 1 other bad wire. Went and bought new AC Delco parts and everything works as it should. Wasted $300 on junk parts. Buy original products and save yourself the hassle and headache. Would give zero stars if I could. Pure junk.
