    These plugs and a new set of wires breathed new life into my aging vehicle. It was long overdue. And I could certainly feel the difference.

        Comments about Autolite Double Platinum Spark Plugs:

        I had a 1987 Toyota tercel that had a problem burning up spark plugs within 3000 miles, I went through just about all brand names of plugs and I found Autolite was the only plug that did not break down. I just removed a set of Autolite double platinum plugs from my daughters 2005 for Taurus that has 180,000 miles on the plugs, the car had the check engine light on for multiple misfire. all the plugs were wore out but showed a perfect burn pattern. a new set of double platnums went in and the check engine light went out.

          Comments about Autolite Double Platinum Spark Plugs:

          I debated between platinum, double platinum, and iridium plugs as a suitable replacement for my copper-based plugs in my V12 Jaguar. I settled on the double-platinum plugs due to price and performance. These were easy to gap with the proper tool and I should not have to gap them again for quite some time due to the double platinum welds. Time will tell if this is a worthy replacement, but my engine is already running like a champ!

          95,000 miles ago, I fell into the more is better, multiple ground electrode trap of a competitor. These plugs were a huge improvement. Good for daily driving, smoothness, and MPG, not so good for the rear tires.

                are these plugs better on gas mileage than the motorcraft plugs

                  A:

                  Different spark plugs affect cars differently. I recommend visiting your local Advance Auto Parts and speaking with an employee there and seeing what they have to say on the matter.

                  A:

                  I doubt you will notice an increase in gas mileage over motorcrafts if you are comparing new motorcraft plugs to new autolites. I check my gas mileage every tank and when I replaced the original motorcrafts with a set of autolites, the mileage did not go up. The engine did run smoother though and I could tell a difference on the highway during acceleration.
