    I used to run the NGK B9EV plugs back in the day in my 390 CR.
    This plug has been discontinued and i came across a denso plug P/N IW-27
    It`s Iridium and has a small diameter tip.
    Anybody have any experience with these?
    I found them on ebay and with shipping they are almost $10 each.

    I have used ND plugs every time I can find them. They never took off because back in the 70s, they didn't have their heat range cross overs matched correctly to NGK. Then they had some manufacturing problems that caused the insulators to separate from the cores. By 1980, everything was all sorted out and good, but by then they had a fairly sullied reputation. I got some for free at a race back in 1980, liked them, kept buying them, stocked them in my shop when I ran it and still have great faith in them. I have my local dealer order them from Parts Unlimited. How that plug for a plug?:D

    I also checked to see if they still made the W27 ES ZU (B9EV equivalent) and they don't. It would have been less expensive.

    Thanks dirtdame,
    How much are you paying per plug for the IW-27 (B9EV eqiv.)?

    Thanks,
