FP Plugs vs Denso

[BrianH87]

Does anyone know how the FP plugs m-12405-m50a stack up against the Denso ITV24? Are they different heat ranges? Or are they similar? Not much info on the FP ones. Only thing I know is Roush uses them in their SC kits. Whipple uses the Denso.

Chart them against eachother
Should tell you the heat range and type of electrode and material

If they are the same heat range and same electrode type, they are same plug. Just pick the brand you trust more

Gen 3 coyote stock have a colder plug already than the gen2 thats why whipple recommends the denso itv24.

Isn't the itv24 a non projected plug? I'm pretty sure it is. I had a set, even when it hot out it idled like crap, especially when the engine was cold. Might be ok for race applications though.

I run E3 but not a lot of people are willing to run them

sound like a loss to me

My main problem here was finding the heat range of the Ford Performance Plugs. Took a while, but they appear to be 7, same as stock 2020 Coyote. So that's not going to work. It'll have to be the denso ITV24 or NGK 6511. I do believe the GT500 SP581 are another option that will work. Thanks for suggestions.

Do they add anything? Longer life, better idle....... I see they are cheaper than the NGK's

They do better in testing but real life they seam to be equal to me in everything but price. They come gapped so they are a lot easier

7 dollars VS 11, I think I might try them.
