Spark Plug W7DC for All 1985-> Airheads & '78-'84 R80 models

Genuine BMW (Bosch) Spark Plug W7DC is correct for the following R-Series "Airhead" models:

• All 1985-'95 models!
• All R80 models, 1978-'84 (incl. G/S & ST)

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.
