    NGK spark plugs

    Just wondering what people are running for NGKs, the TR6s, TR5s, etc.
    My car is N/A with the intake cams advanced 4 degrees.
    Thanks for any info you may provide and have a great day.

    Here is information on spark plugs I've accumulated:

    Stock Heat range
    Autolite – 104
    Autolite Double Platinum – APP104
    Autolite Iridium / Xtreme Performance – XP104
    Champion Copper Plus – RS12YC
    Champion Platinum Power – 3401
    Champion Double Platinum – 7963
    Champion Iridium – 9204
    Bosch – BSH7571
    Bosch Platinum – BSH4205
    Bosch Platinum+2 – BSH4305
    Bosch Platinum+4 – BSH4458
    NGK V Power – TR55

    NGK Laser Platinum – PTR5C-13

    I use the TR6 plugs and a colder thermostat.

    Wow-thanks so much for the information.
    So are you running a 180* thermostat?

    I've been running NGK TR6IX (1 step colder) plugs with a 180 degree thermostat.

    Yes. You'll need a "tune" to take advantage of the colder stat & plugs.
