    You want the Plain-Vanilla  NGK #4339 DCPR8E, Standard Nickel Plug WITH the Removable Terminal Nut.

    Or the Irridium Version at 3x the price.


    BLYB = Retail Blister Package

    IX = Irridium

    KP,KC = Multi Electrode 

    Solid = Non-Removable Terminal Nut

    - - -

    Interesting that all the Multi-Electrode versions have Non-Removable Terminal Nuts.

    Other than that, they are 1/3 the Rotax price.

    My IS came with NGK DCPRE spark plugs and have worked very well they cost about $4 each.

    Recently ROTAX have decided to say you must use their own which are 10X the price.....


    IMHO this is BS....


    but what do others say ?


    NGK forbids the use of their products in aviation so Rotax had to change suppliers.

    The new supplier had to found, and they had to agree to aviation use. Of course, this raises their cost, and with such low volume we have in aviation, the price demanded was high.
