        What heat range are these? I understand they're 1 colder than stock, but what is that? I already have NGK plugs in a heat range of 7 and i'm trying to figure out if it's the same or not.

        • The stock heat range will be a heat range of 5. The Ford Performance 0-Degree Spark Plugs (08-10 GT) are one step colder then stock putting these spark plugs at a heat range of 6.

        Will they work in 07 gt with Accel yellow coils

        • Hey JustinJT5U3148420, The plugs you have listed will not as they're listed for 08-10. However check out the link below I have posted some plugs that will work for your particular application. https://www.americanmuscle.com/frpp-16mm-sparkplugs-0508gt.html

        I ordered the 50373 plugs for my 07 GT can I use them? 07 GT 4.6

        • The Ford Performance 0-Degree Spark Plugs (08-10 GT) will not work on your 2007 mustang. This will only work for 08-10 GT mustangs.

            Great spark plugs

            These spark plugs are a must for any force inducted mustangs. I felt a big difference on my 427R, it responds a lot faster. I would highly recommend these plugs!

            Tune Up

            Mustang ran "great" but it was "tune up time" (miles). I was really surprised at the performance gain these spark plugs made. I also put on 4 new tires, four wheel alignment/balance/new KandN filter so I think "the combination" probably made a "New Car Go Fast Feel"....

            Not realy Ford plugs

            I'm not sure why these are advertised as Ford Performance plugs when they are not Ford branded. The plugs fit fine and the car runs fine but I was expecting a Ford product based off the description. What arrived was a standard set of NGK Iridium plugs that I had to re-gap. No big deal but just not what I thought I was buying or worth returning since I needed new plugs. You can however buy these plugs cheaper as they arrived thus the low rating. I installed these as a maintenance item to my car so I wasn't expecting a performance gain. Since it's requested for the review I put that at 2 stars as you're not really gaining much, if any, HP from plugs unless your old plugs were toast already. Although I'm rating them low, they fit fine and perform as expected in my M-90 SC car.

            Late 08'-10' 4.6 boosted spark plugs

            My car has been running brisk racing plugs and has had a weird misfire with only 5k miles on the brisk plugs.I recently installed the ford racing(which is an Ngk plug once u open the box)the car literally runs like stock and perfect then when the kennel bell kicks in it's like the smoothest rocket you've ever felt I say these plugs are 10/10 and p.s. there perfectly pre gapped also.

            Bought these 0 degree plugs to run nitrous. Not only do they work great with the nitrous but the car gained about 2mpg and runs much smoother on my daily commute.

            I notice and immediate increase in gas mileage and acceleration for my 2009 Ford Mustang GT California special. It took about an hour and a half to replace old spark plugs with this new set.
