The Champion REM37BY is a resistor-type massive-electrode aviation spark plug designed for Lycoming and Continental aircraft engines that are prone to lead fouling. Its projected-core (“BY”) design helps the plug continue firing under heavy lead deposit conditions commonly associated with 100LL operation, extended taxiing, and low-power use.

The REM37BY is a popular choice among aircraft owners and mechanics for engines that frequently experience fouled plugs during ground operations or training use. Its resistor construction helps reduce radio frequency interference while providing dependable ignition performance and long service life.
