              I installed these in my 97 F150 and immediately lost 50 miles per tank. I pulled them to double check the gap, and they were true. Replaced with a different brand and got the 50 miles back. I will not buy again. Waste of 15 bucks for the plugs and whatever I lost in the MPG.

                Out of a new set of six of these, one failed within the first 500 miles. Now at about 2500 miles later, another one has failed. These are the first plugs that I have ever experienced totally failing in 40 years of driving.

                  Comments about Autolite Single Platinum Spark Plug:

                  I used these plugs before and have installed them in every truck I have bought. I have noticed increased fuel mileage and increased performance right from the start and they last for more than 50 thousand miles at a time. I average over thirty thousand miles a year on my truck and have gone a couple years between replacement with out any problems or plug failure or drop in performance. I would recommend these plugs to any one who want a good plug with out breaking the bank and want's to to protect their motor.

                  One started misfiring only after 150 of use. I drive very conservatively given the high gas prices. I changed out the plug and no misfire. I have learned the hard way to use oem spark plugs due to the fact to not mess around with the manufactured designed combustion for the vehicle. I changed out all the plugs back to AC Delco and vehicle runs great.

                      You could change the air filter, fuel filter, spark plug wires or coils, and maybe a belt.
