Spark Plug W5DC for 1970-'84 Airheads (See Applications)

Genuine BMW (Bosch) W5DC Spark Plug is correct for the following 1970-'84 "Airhead" models:

• R50/5
• R60/5, R60/6, R60/7
• R90S
• R100/7, R100S, R100RS, R100RT, R100CS, R100T
• R65 (1979 only)

NOTE: These BOSCH Spark Plugs are the correct NON-resistor spark plugs for Airhead models called for by BMW. They are only available from BMW dealers, because Bosch stopped distributing non-resistor plugs EXCEPT for the three types: W5DC, W6DC, W7DC, which they provide exclusively to BMW and are sold only with BMW 11-digit part numbers. Do not use Bosch WR5DC, WR6DC or WR7DC resistor plugs.

Don't forget spark plug gap gauge to double check the electrode gap. See recommended products.
