RC Engine Spark Plugs

Spark ignition engines rely on a plug that fires reliably at the operating temperature of the motor, and this category covers spark plugs for radio-control gasoline and spark ignition power systems. A plug in good condition contributes to steady idling and consistent throttle response, which is why many pilots keep a spare on hand.

NGK CM-6

The NGK CM-6 spark plug is a widely used size in small spark ignition engines, and it is the plug listed in this category. Because a single plug type covers many of these engines, matching a replacement is usually a simple task. Checking the electrode gap and replacing a plug that has fouled or worn are routine parts of keeping a spark ignition engine running as expected.

A fresh plug is modest insurance against a rough running motor at the field, and swapping one takes only a few minutes with a plug wrench.
