Been using these plugs the last few years with my supercharged 2010 GT coupe. Never have an issue. Highly recommended when doing a supercharger install to purchase these plugs.

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.

ConfusedGuy

  • 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.

  • 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 increase in gas mileage!

    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.

    Wow, More Spark More Power

    There was a big mix up with the actual plugs that fit my 09' GT. But the people at A/M walked me through it with no problems, excellent plugs

    0 degree spark plugs

    Great product! I looked everywhere for a colder plug for my turbo Mustang. These plugs saved me a bunch of $$! I had the car tuned and its making more power with better mpg. I highly recommend these plugs for any 08-10 GT running blower, or turbo!

    Ideal for Supercharger Application

    Got those for my Roush TVS. Wanted to stick with FRPP. Actually the plugs are NGK's in a Ford Racing box. They come gapped at 0.028 and depending on the specific application they need to be regapped. Fine product at a great price! Would recommend to anyone who needs colder plugs.

    NGK 7554

    I ordered these and actually received NGK 7554 plugs. After a little research online I found that these are the equivalent to the FRPP 0-degree and this was confirmed by AM saying NGK makes the plugs for ford. Plugs installed without issue and work great.

    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.

    GREAT PRODUCT!!!

    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.

    It does what you need them to do apparently there are other spark plugs great for FI but at the time I didn't know that. No complaints here
