    High quality spark plugs. I could tell a difference on the starting for my Taurus 2000. Now, it starts and runs smoothly, and quietly. Make sure to check Autolite webiste. They usually have mail in rebate offers, so don't throw away packages.

      Comments about Autolite Double Platinum Plug:

      The spark plugs worked well and was already almost gapped to the neccesary distance. I think the plug will last a long time and will improve my engine efficiency and power for the long haul. If there was something I would change about them it would be nothing because everything about the spark plugs are amazing. All I had to do to install this product was use a 7mm socket and remove the coil then remove the old spark plug and then put the new one back in. It was very simple and only took about 1 hour to finish installing these in my mustang gt.,............................................................................... ........... . ..

          Comments about Autolite Double Platinum Plug:

          I used these in my 1999 Contour SVT 2.5L DOHC HO engine, replacing the original-style Motorcraft plugs. They worked great, and in conjunction with some new Autolite Professional Series wires (PN 96644) they stopped the low-speed hesitation I was experiencing beforehand.

          I accomplished the job with a 3/8" ratchet with a long extension, 5/8" spark plug socket and a 9/32" socket.

          I use Autolite Platinum plugs in ALL my vehicles, and always recommend them to friends and family.

          NOTE

          * These plugs are NOT pre-gapped. Don't forget to gap them before installing!

          * If you're using them on a DOHC V6 or V8 engine, you MIGHT have to remove the coil to get to the rear plugs. The 4 bolts holding my coil came off easily with a 9/32" socket. ALSO: The coil has 2 ground wires attached to it, so don't forget to re-attach them after installation.

              Should have replaced these about 15.000 miles ago. New plugs increased the millage about 2 mph. Because I needed to remove the upper air manifold along with other assorted parts to get to them, I wanted to take no chances and replaced the wires as well. Great investment.

                Comments about Autolite Double Platinum Plug:

                I had a couple misfiring cylinders on my 2001 Mercury Cougar. Bought these plugs along with Autolite wireset and they work great. The plugs were easy to install, even the back plugs which I was able to easily reach with a 12" extension. I replaced the plugs myself while the car was parked in the parking lot and took me about 30 minutes for just the spark plugs (first time ever replacing them). Spend a little extra and get these quality plugs! Most often it will benefit you in the long run.

                      I would suggest you to refer your vehicle owner's manual for the exact torque specification on the spark plugs in order to avoid intermittence.

                      You can find the correct gap in your owners manual, or there is a data sticker some place under the hood, or on the core support(near radiator, repair service manual, and the parts store sales associate can tell you.

                      These plugs are pre-gapped. You need to purchase the correct plugs that have the correct gap.
