Kitfox™ SERVICE LETTER #3

SUBJECT:    SPARK PLUGS AND SHIELDS

TO:    ALL Kitfox™ OWNERS

FROM:    DENNEY AEROCRAFT’ COMPANY

SPARK PLUG SHIELDS: Some builders in the field have experienced problems with the optional metal shielded spark plug connectors. If you have some in new condition, please return them for credit and we will send you the new style resistor plug connectors. The shield to use is NGK part number LBO5EP or LBO5EV.

SPARK PLUGS: If you are using NGK part number LBO5EP or LBO5EV, do not use the resistor type spark plug such as NGK BR8ES. When both are used together, the resistance limits the spark plugs ability to operate at maximum efficiency resulting in a loss of power. The correct plug to use is the NGK B8ES.
