    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.

      Garbage. Misfire a lot under boost. The brisk spark plugs are the far better choice

      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.

      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.

      FRPP Spark Plugs

      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.

      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.

      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!
