Packaged Items
SinglePack of 12

Overview

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.

Champion Aerospace designs and manufactures Champion-brand piston-engine ignition components for both OEM and aftermarket for general aviation aircraft applications. Every spark plug manufactured has built-in design advantages that assure longer life and greater reliability.

** The "Iridium S" sparkplugs replace the Platinum and "W" Iridium types. Increased bore diameter improves scavenging action. Greater clearance volume can accept more combustion deposits. Single Iridium electrode offers greater resistance to lead attack. Easy to clean Easy to gap


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.

On time and as specified

CHAMPION SPARK PLUG REM38E

March 6, 2024

Good product but price is more than Tempest plug. However the wrenching on the Champion plug are higher on the shaft and allow for clearance for CHT spark plug gaskets in the spark plug counterbore of the engine. Tempest plug wrenching a lower (more towards tip) and will not always clear a CHT gasket probe.

Hard to understand why these are priced so high when it is impossible to tell the difference from a Tempest plug that is ~20% less expensive.

Q: Do the Spark Plugs REM38E come with a new gasket p/n STD-295?

They do come with a new copper gasket, but no specific part number.

Q: What is the difference between the REM38E and the REM40E?

The 38 and 40 refer to the heat rating position of the plug. Champion does not provide specific temperatures, only that the higher number has a hotter heat rating and the lower the number the colder the rating. Which plug to use should be determined by the aircraft mechanic depending on conditions of operation and application.

Q: Do the Champion spark plugs come pre-gapped?

The spark plugs are labeled with a gap of .016-.021. It is recommended to check the gap before installation to be sure it is set where you need it to be.

Q: What is the thread pitch on the 18mm mounting thread n the REM38/40E
