NGK CM-6 Spark Plug

This spark plug is used in all DA/DLE engines. Is also used for the SV17, new version SV50 and SV100, RCS 50VT four stroke and all RCS radial engines.

While DLE engines are great, the original equipment spark plugs are not! While some plugs are fine, some are not. Plugs are not covered under warranty. Should you experience any running problem, the first change the spark plug. We recommend carrying a spare plug at all times.

During the break-in period when you are using petroleum based oils at 32:1 and running rich, this is a deadly combination for spark plugs fouling. Keep a set handy, and avoid running too rich.
