The spark plugs for the AGG/AKR/2E are...
NGK BUR6ET - 0.8mm gap
NGK 14GH-7DTUR - 0.8mm gap
Bosch W7LTCR - 1.0mm gap
Should be 3 electrodes, They do make special ones now, which are upgrades, but the 3 electrode is the best due to the swirl of the air fuel mixture, they just seem to react better.
NGK For the win - i always have trouble with bosch.
