NOTE: Applied as lower, secondary spark plug .
Vehicle Manufacturer: BMW
Application: BMW Airhead Models
Make/Model: BMW Dual plugged Airheads and R50S, R69S, R69US
Manufacturer #: BMW 07 11 9 976 335, NGK: BP7HS and Bosch: W260T1 / W3AC
Power Rating: Heat Range 7 (9=Cold / 1=Hot)
Resistor: 5K ohm
(See APPLICATION TABLE tab BELOW to verify vehicle fitment)
Original Equipment : NGK NOTE: A plug with a low heat range number is a cold plug that quickly dissipates heat to the engine block and cooling system, while a high heat range is a hot plug that retains heat. By properly selecting the heat range of the plug, it ensures that the plug will operate between the plugs designed operating range of 500-900 degrees Celsius. In this range, the spark plug will be self-cleaning, yet will not be hot enough to pre-ignite the air/fuel mixture
