Spark Plugs & Ignition Harnesses

Aircraft spark plugs and ignition harness for piston engines. The collection holds Champion and Tempest plugs in massive-electrode and fine-wire versions, shielded types such as RHM38E and REM40E, NGK DCPR8E plugs with removable or solid terminal nut, and the Champion M4012R complete ignition harness.

Plugs are listed by part number. Match the number to the engine manufacturer's approved plug list before ordering, and note the thread and shielding type of your engine.
