Rated 5 out of 5 by The best I ever used I have a 2001 Dodge Ram with over 240,000 miles and my last tune-up I used the Autolite plugs and I have regained gas mileage and power to the engine. May 30, 2015
Rated 1 out of 5 by Not GOOD. I bought 4 plugs for a VW Jetta. I completed the installation and the check engine light came on. It took me 2 hours to determine which plug was bad. The upside is I was given a new plug for free. The down side is this job took me three times longer than it should have. I will never buy Autolite plugs again. December 28, 2014
