    I have been using NGK BP6ES (7333) plugs in my 1979 Boxer for 20 plus years with good results. My car is still running on the original Dinoplex.

    It appears NGK has discontinued this plug and is recommending the resistor plug BPR6ES (7331).

    What have you guys used recently.

    I have no problems with the BPR6ES.

    Try champion copper plugs. Don't be tempted to use platinum or iridium plugs, they won't work as well.
    Champion was probably the original brand plug in your car.

    here in germany it is not so easy anymore to get those champion plugs, but still available
    and I still have 3 sets of new champion N6YC in stock :)

    but I wonder: the conversion list says champion N6YC is equal to NGK BP8ES, but you use BP6ES

    Thanks for the comments. I tried buying from some of the folks on ebay and amazon that advertised the BP6ES but nobody had any. Though I'm tempted to try the resistor plug BPR6ES I'm going to a Champion N7YC. I realize the Boxer operating manual specifies a N6Y plug but that seems a little too cold for me. The N7Y converts to the BP6ES and the C (for copper) sounds like a good idea for a buck more.

    I'm going by memory here. In my early testarossa it called for champion A6G plugs. Many years ago when I changed the plugs, the first time I found champion part number 809 was the best option. I've used them ever since and have had excellent results.
