    I am going to replace mine - N6GY plugs are long gone - what is the consensus on replacements? US driving, not a lot of high speed/high heat work so I don't want a super cold plug...

    Thanks

    I've had good luck with HGK BP6ES.

    Whatever you choose, just use a bit of anti seize paste (like copper slip) when fitting.
    Long time and no action can make the plugs seize solid.
    I had to remove a cylinder head and get one plug's thread spark eroded out.
    Worked out perfectly, but took a lot of time and energy!

    I'm blanking on the code but I used the latest iridium plugs in the stock heat range and they never loaded up when idling round town. Did the same on my tr6 and will never go back to the old copper plugs
