Rated 5 out of 5 by from Autolite Platinum Spark Plug I replaced this Platinum grade over the original Copper Resistor spark plugs because I want my old engines to run cleaner and burn more leaner comibushable cycles and less carbon deposit in the valves and head. I have countless of thousand miles on my S10 truck and I have decided to upgrade to a better spark plugs to run smoother, more power and better MPG. Also, it does helps to PASS smog testing results.

Rated 5 out of 5 by from Autolite Spark Plugs Chrysler Corporation used to use & recommend Autolite spark plugs until Ford bought Autolite in 1961. So Chrysler switched to Champion spark plugs instead. Ford sold Autolite to Bendix in 1973, and Allied Signal bought Bendix in 1983. Ownership becomes very confusing after that, involving Honeywell and later Fram. Autolite, Champion, and AC all make excellent spark plugs.

Rated 5 out of 5 by from spark plug and complete tune up I think the Quakertown Pa. PepBoys has the best service specialist and technician I have gone to different Pepboys and never received top service. Joe who is always at the service desk is very honest and professional and always there to help.
