The Champion line of spark plugs is the preferred brand of leading aviation companies, repair hangars and professional pilots. With more aviation spark plugs produced than any other company in the world, Champion is undoubtedly the leader in spark plugs for small aircraft including Cessna, Piper, Cirrus and Mooney models.
The Champion brand of aircraft spark plugs features built-in design advantages for superior performance. The plated threads inherent to each spark plug prevent seizing, while the two layers of corrosion protection offer durability and a longer service life. Champion spark plugs are built from a combination of durable materials that provide greater reliability than other brands of aircraft spark plugs. The silicon carbine resistor paired with the fired glass seal prevents voltage drains and gas leakage that could severely damage the plug and aircraft engine. The device’s copper core provides the most efficient heat transfer, while the aluminum oxide insulator and nickel alloy electrodes prevent the spark plug from cracking.
The REM37BY is a 18mm, foul resistant type plug with 5/8-24 thread and is 3/8" shorter than standard champion plugs.
NOTE: Spark plugs are shipped in factory sealed plastic cases. Opened spark plug cases make the spark plugs non-returnable. Please do not open any spark plug until you are sure you have received the correct spark plugs for your application.
