RFI Suppressors

The Champion Spark Plugs that we offer that begin with the letters “Q” and “R” include RFI suppression, so they won’t affect your radio or navigation equipment. R-type plugs include Champion’s SAC-9 RFI suppressor, which is a resistor made of strontium carbonate, aluminum oxide and copper oxide powders.

Q-type plugs limit RFI with an inductive suppressor, which consists of a wire wound inductive coil that reduces RFI without negatively affecting ignition performance. Q-type suppressor plugs are specified for most Evinrude and Johnson outboard engines with CD ignition. Usage of non-Q types (or standard resistor plugs) can actually cause engine misfire and a loss in performance.

Plug Selection

To ensure optimum performance please consult your owner’s manual to determine the correct spark plug for your engine.
