    what spark plugs are you using on the Grob 2500 E1 ?

    Mine is a 1984 G109 B I currently have the Bosch WC7D, but have been difficult to find.  Next spark plug change I think will not be able to find them.
    Any substitutes?

    thanks

    Leobardo,

    I don't know about substitutes, but Airborne Composites has a large quantity of the correct plug available for sale . Check them out.

    http://www.airbournecomposites.co.uk/

    then push the sales tab on the left side.

    Now that you have had it for a while, how do you like your new bird?

    hi, very good experience with the G109B , flown 80hrs from Feb to
    date.
    Everything very simple and without any trouble.
    Just now with the annual service I need the spark plugs, but finally
    found them yesterday at clubplug.net

    Enjoying very much

    Are the WC7D sparks plugs used on the Grob 2500 E1 engine shielded aircraft type or
    unshielded automotive type?


    Still looking for spark plugs options for my L2000 engine (G109)

    Thanks
    Bill

    Hi Bill,
    The sparks plugs to be used on the engines Grob 2500 E1 or D1 as
    request by Grob are either the
    -Bosch WC7D (VW N° 100 039.01) or
    -Beru X14L (VW N° 100 040.01) or
    -Champion REN 30S

    In this writting I noticed that Grob engine manual from where I copied
    these references, gives also relevant VW (Volkswagen) part numbers.
    May be these spark plugs are also used in automotive competition and
    available at VW parts suppliers? Somebody knows?
    Amicalement

    The Champion REN30S is available but at exorbitant prices of more than GBP 200 each or you need to have them 'made to order'  made by Champion. Any alternatives ? Diameter of thread 14mm and 19mm reach. Does one have to replace the spark plug leads  and go to a 'push-on' spark plug ?

    Any advice ?
