Onan 3.6kW Spark plug

Spark plug to suit Onan 3.6kW petrol generator.

The use of Green Label, resistive, original equipment spark plugs will keep your Cummins Onan genset working properly. Use of other non-resistive plugs can cause generator shut downs without fault codes.

Spark Plugs

Genuine Cummins Onan spark plugs come gapped correctly from the factory for your RV generator engine. Spark plugs purchased from other sources come gapped for automotive engines, which are gapped much larger. When regapping, the ground strap must be bent and it may not cover the entire electrode which will reduce spark plug life.
