    I replaced my original plugs with these,(120,900 miles on them) when I finally got to the old ones in my car I found I was replacing the same plugs that came in the car when it was originally sold. Autolite's work like a dream. The car is running smoother than ever and I believe I will notice some mileage gains once I get a chance to drive it for a while.

    Ive used Autolite "standard" plugs for over a decade with no issues BUT.

    Well with these Platinum plugs I bought 6 & only 2 out of the 6 had a electrode that was precision centered with the ground strap.

    I Bought 6 more & only 3 was centered that time.
    There was no consistency as to the electrodes location to the ground strap.

    There all usable but the Quality Control is Poor.
    They have a 3yr warranty in which they will no doubt last this length of time.

    If anyone implys that this plug is a Performance plug then there mistaken!

    The OEM plug did not have this offset issue.

    Good Day.

          If you have easy access to spark plugs, this will be good for 25,000 miles.
          On the other hand, if you have very diffilcult access to spark plug like my 98 b2500, I would go for double platinum for around 75,000 miles before another change!

              platinum plugs was what was in my vehicle. i checked one plug one day to see the shape they were in and found it burnt down somewhat and figured its time to replace them. after the job was done there were just two plugs with wider gap than desired. 109000 miles on them, guess they done their duty.

                The gap was nowhere near consistent & since these plugs fit numerous applications be prepared to set them to your vehicle's recommendation. The staff at Advance was helpful in provideing that information for my Ford Ranger. It's funny this is the first 4 cylinder engine that I've seen require 8 plugs, of course one side of the engine had easy access but getting to the plugs on the left side along with routing the new spark plug wires was somewhat challenging. Overall the tune-up was a success and the truck drives better.

                    A:

                    Hi Meka! I'm glad to help you. This Autolite spark plug traditionally leaves the factory pre-gapped for its application. However, a plug may fit hundreds of engines. Gapping the plugs to your engine’s specifications is important to prevent pre-ignition, detonation, fouling and poor fuel economy. Even if the preset Gap matches that required by your engine, it is always good practice to physically check the Gap as it may have shifted during transportation.

                    Hi Jim! Good question, though. The heat rating of the spark plug is indicated by a number; lower numbers indicate a hotter type, higher numbers indicate a colder type.

                    A:

                    With reference to your inquiry on the Autolite Single Platinum Spark Plug - part# AP104, the only way a plug can blow out is if the threads are damaged/non existent, this usually happens from over tightening the plugs and is very easy to do on aluminium heads. Fitting a heli-coil is the way to go to fix it. However, I would suggest taking your vehicle to a certified mechanic for a proper diagnosis.

                    A:

                    The Spark plug gap for a 1998 Ford Explorer AWD 5.0L is .054. The installation process is simple and you can replace it yourself. Locate the spark plug wires on the sides of the Explorer's engine. Pull back on the wires to reveal the spark plugs. Turn one spark plug wire by its boot, which is the larger piece at the end of the wire. Place the socket over the spark plug and unscrew it until the old spark plug is free from the cylinder well. Brush out the wire boot and cylinder well to remove any debris. Screw the new spark plug into the well until it is tight. Reconnect the wire and turn it halfway to the left and then all the way to the right to lock the wire on the spark plug in place. Only work with one spark plug at a time to avoid causing any damage to the engine of the Explorer.
