Champion REM40E Massive Electrode Spark Plug

Description

You’re running through your preflight on a humid morning and spot a plug that’s been fouling intermittently on the left mag—a classic sign it’s time for fresh plugs. The Champion REM40E Massive Electrode Spark Plug is designed for Continental and Lycoming engines found in Cessnas, Pipers, and Beechcraft aircraft. Its larger electrode mass helps maintain a stronger spark across a wider operating envelope, particularly useful in aircraft that see variable loads and altitudes. Before ordering, verify your engine’s original equipment specification and consult your aircraft’s maintenance manual to confirm fitment.

This plug sits in the middle ground of aviation spark plug options—not a fine-wire design, but engineered with a robust electrode that resists erosion under standard operating conditions. Owners appreciate the extended service life compared to conventional plugs when properly gapped and installed. As with any spark plug replacement, follow your engine manufacturer’s torque specs and gap requirements exactly. Keep a fresh set on hand for your next condition inspection or when an engine run reveals uneven mag drops.
