Overview of Champion Spark Plugs
In the early 1900s, small planes flew with single ignition systems powered by adapted automobile engines using Champion-brand automotive spark plugs. By the 1920s, the company had developed innovative spark plugs designed specifically for the aviation industry.
Now, as the preferred supplier of spark plugs for general aviation aircraft, Champion Aerospace designs and manufactures Champion-brand piston-engine ignition components for both OEM and aftermarket applications.
Champion manufactures more high-performance, aviation-grade spark plugs than any other company in the world.
All Champion Aviation Spark Plugs are identified by type designations selected by virtue of the plug design as applied to the following Spark Plug Number and Symbol Chart. The symbol is composed of a rating position number together with prefix and suffix numbers to indicate major plug design characteristics.

| 2. Barrel Style | None -- Unshielded | E -- Shielded 5/8"-24 Thread |
| H -- Shielded 3/4"-20 Thread (All Weather Plug) | ||
| 3. Mounting Thread -- Reach -- Hex Size | B-18mm 13/16" / 2.06cm 7/8" / 2.22cm | M--18mm 1/2"/1.27cm 7/8"/2.22cm |
| L-14mm 1/2"/1.27cm 13/16/2.06cm | U?18mm 1-1/8"/2.85cm 13/16/2.06cm | |
| J -- 14mm 3/8"/0.95cm 13/16/2.06cm | ||
| 4. Heat Rating Position | Low number--cold | High number--hot |
| 5. Electrode Design | None-Conventional single | E -- Two prong massive N -- 4 prong massive |
