The R-2800 was a twin-row, 18-cylinder radial engine used extensively in major Allied aircraft including the P-47 Thunderbolt and F6F Hellcat, making components from these engines highly collectable today.

Each R-2800 engine used 36 spark plugs (two per cylinder) as part of its dual ignition system—highlighting the importance of these components in reliable high-performance operation.

Champion spark plugs were widely used in U.S. military aircraft engines and were designed to withstand extreme temperatures, pressure, and lead deposits encountered in aviation service.

Examples such as the C34S/C35S type are specifically associated with R-2800 engines, reinforcing the authenticity of this piece as a correct wartime component.

🧭 Historical Significance

This spark plug represents a small but vital part of the ignition system that powered Allied air superiority. The P-47 Thunderbolt—nicknamed the “Jug”—was one of the most rugged and heavily armed fighters of WWII, and the R-2800 engine was at the heart of its success.
