Review on AUTOSAVER88 Ignition Compatible Trailblazer Colorado by Ken Vargas

Installed about a week and a half ago and so far so good. Fuel economy increased significantly by about 2 mpg. The product is as good as acdelco if not better and at a much better price. I drive about 3000 a month and so far no complaints. UPDATE: After a little over a month and 15,000 miles they still work like new. The price is a lot better than Delco's AC brand, and the performance is equal if not better. UPDATE: There was a misfire in one of the coil packs. Emailed customer service and within 3 short emails the replacement set was on its way, actually arrived a day early. The customer service was exceptional, the best I have ever experienced in an online retail transaction. Even if 1 coil pack failed in a short time, the quality of the parts is very good. I drive in 1 month what the average driver does in 3 months.
