Description

The Tempest UREM40E is a spark plug engineered for reliable ignition in general-aviation piston engines. Designed to withstand the thermal and pressure demands of flight operations, this plug delivers consistent firing performance across the operating envelope typical of Cessna, Piper, and Beechcraft aircraft.

Regular inspection and replacement intervals, as outlined in your engine and aircraft maintenance manuals, help ensure dependable cold-weather starts and consistent performance throughout the service life of your engine.
