RFI Suppression Technology:

Champion spark plugs beginning with "Q" or "R" designations include built-in RFI suppression to prevent interference with radios and navigation equipment. R-type plugs feature Champion's SAC-9 resistor made from strontium carbonate, aluminum oxide, and copper oxide powders. Q-type plugs use an inductive wire-wound coil suppressor, which is specified for most Evinrude and Johnson outboard engines with CD ignition systems.

Application:

Suitable for automotive, marine inboard, I/O, outboard motors, and personal watercraft applications. Consult your owner's manual to verify the correct spark plug heat range and type for your specific engine.
