    looking to swap plugs, I see a lot are using ngk-6510 for “stock” boost levels.
    What about smaller pulleys?

    Stock is 6509
    One step colder is 6510

    Go 6511?

    Whipple with 3.37 pulley

    OK i saw later you posted in 5.4 which is totally different spark plug. ITV22 are a step colder then recommended. ITV20 for a stock engine , ITV22 for whipple recommended boost. ITV24 would be 2 steps colder. 22's have worked for me and i run same plug in my 14 ecoboost at 20psi boost.
