Important Installation Note: Brisk Racing Spark Plugs required very little torque to install correctly (10-15 Nm). Overtightening *any* spark plug can damage it. A higher performing spark plug does not need to be *tighter* than a stock bike spark plug. It's a spark plug, not a hex bolt! Click here to see the torque specification for your Brisk spark plug.
*** spark plug firing tip configuration projects into the combustion chamber for better air/fuel access and ignition. ALWAYS CHECK FOR SUFFICIENT PISTON CLEARANCE to avoid possible spark plug and/or engine damage. ***
