These are my 4th set. Very satisfied. Just make sure to use anti seize and these are a piece of cake to intstall. Use them with a 100shot of nitrous and have never had a problem. Reset them at 035 for

    Autolite Plugs

    The plugs are great replacements and highly recommended for stock or mod engines. I used this brand to stay as close to stock replacement as I could for performance. I installed a Nitrous kit so I had to gap plugs for a colder burn. Make sure you have the special gapping tool and a set of mini feeler gauges before you do the swap out if you are doing for NOS,Turbo or Super Charger.I will use these plugs again next time I need to change out.

    Perfect for turbo

    These compliment any supercharger, turbo, or nitrous and are a needed component when installing one.

    Better perfomance

    Just had thees installed as I was getting a misfire prior. Now the car runs smooth and no misfire. I also have noticed a slight increase in gas mileage.

    STAY AWAY!

    I got these plugs even though I had heard about the coating flaking off and boy was I sorry I bought them. I was going to take my car out to my local drag strip over the weekend but on Friday my car started spittin like crazy and I got it to throw a code so I could check it with my programmer. It turns out that I was having missfires in three of my cylinders after only having the plugs for a week. I will never buy these again and I will warn everyone I know to stay away from them.

    Perfect Fit

    I needed a set of replacement plugs, these seemed to be the best to bring my spark back. They fit perfectly and had no issues. It seemed to run a little clearer with new plugs too.

    outstanding spark plugs

    My ford motorcraft spark plugs have some mile on them. after replacing them my fuel milage went back up and gain a little more horse power. If you look for something to help with the gas milage and give you more horse power this is the way to go. I would recommend that if you have 50,000 or more mile you should think about changing them.
