Champion RA6HC Spark Plug 809 for Honda BF20A OHC 4-Stroke 20 HP Outboard Engines

The Champion RA6HC marine spark plug, identified by Champion as Spark Plug # 809, is a quality OEM-replacement plug built for reliable ignition in demanding marine environments. It features a copper core center electrode that delivers increased conductivity and precise heat control, helping the plug wear evenly over its service life rather than degrading unevenly under load. This construction is engineered specifically to resist overheating during heavy engine loads, a common stress point for small outboard engines that run at sustained high RPM.

Beyond heat management, the Champion RA6HC resists fouling, which helps maintain a clean, consistent spark and smoother starts even after periods of idling or trolling. Its corrosion-resistant construction stands up to the salt air, moisture, and humidity that marine engines are routinely exposed to, protecting the plug's threads and electrode from premature degradation. Champion backs this with a design intended for dependable, proven performance rather than a stopgap fix.

The Champion RA6HC (Champion 809) is fitted for the Honda BF20A OHC 4-Stroke 20 HP outboard engine. Boat owners and marine technicians can install it as a direct OEM-style replacement when servicing this engine, whether for routine maintenance or troubleshooting ignition performance.
