    Im procharged with a D1x putting down 723 rwhp and i want to know if i have the best plugs in my engine. My installer gave me NGK 6510’s heat range 7. But ive been reading about the improved conductivity of the Silver electrode of the Brisk plugs. Tell me if it would be better to switch over to Brisk.

    Thanks

    It a tough call. But make it easy and go with tuners recommendation.

    Just throwing it out there that several people have had issues with the electrode insulator breaking on Brisk plugs. After it happened to me I put in another set that I already had which have been good now for some time, but I plan on switching to NGKs after this set.

    Seems the only time people have issues is when...

    1) Plugs get dropped during install
    2) Improper gap
    3) Bad plug out of the box. (out of the thousands of plugs I have done, thats happened maybe twice)

    Stick with the NGK 6510s. I run them on my Mustang and my Raptor. Very good plugs.

    I dont why people run iridium's they are designed for longevity, a cooper plug is a much better conductor.

    We've been running NGK 6510's on our coyotes and late model modulars with great success. I've had them on my car for years now as well, running 14 psi and gapped to .028.

    Go with what your tuner says... Adam would have you always stay gapped between .025 and .030.

    I have the same issue. Just pulled my plugs and found one with a cracked ceramic insulator. I run NGKs. I have new ones on the way and I'm hoping that solves my PO300 issue.
