Wow as I have some good exciting news about these spark plugs. I installed them in my 97 Ford F-150 4.6 V8 right along with some new Duralast Spark Plug Wires right, when I turn the ignition over to reveal the results, I was excited at the results of hearing the smooth idle of my ride with them new plugs and wires. I am impressed with the performance of those plugs. They improve my engine performance. They are top notch. I definitely recommend them to anyone. I put my trust in them. They stopped the low speed hesitation i was experiencing, now I do not hear or feel it anymore. Truck feels better. Great investment in them, Autolite you're the best. I had a misfiring on cylinder 3. I am back on the road, they exceed performance to me, I give them a A+++++ beyond. My truck drive very smooth now, better than before. I do not feel like I can feel the idle at a stop light or stop sign, man I got some excellent plugs, now time will tell how good they will last from now until 5 years of the warranty. I'm ready to see will they improve great gas mileage.

        Comments about Autolite Double Platinum Spark Plugs:

        i replaced all the ignition coils to the super accel ignition coils and originally had motorcraft platinum on my 4.6l so i was looking at all the reviews on these autolite double platinum and they were all nothing but good reviews so i got them and once i put them in oh man a world of a diffence i mean from horsepower increase throttle response, to gas milage increase, acceleration increase but with the acception that i have all performance ignition coils. overall worth the money so far and goes for the people that dont really know much about cars and trying to do performance engine work get these double platium park plugs with any performance ignition coils , but yet most ignition coils are copper so if you get some that are platitum your gonna get maximum results for your engine! idk for anybody else but for my 4.6L its perfect!! fyi copper conducts better electricity but burns outs more quick than platinum last longer and conducts just as well

                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.

                A:

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

              • A:

                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.
