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.

* Shielded barrel thread size. Check barrel size - 5/8x24 or 3/4x20 threads before ordering and select proper plug number, See page 236 for Sparkplug Application Table.

** 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.

Initially, the incorrect spark plug was delivered (due to mislabeling) but Aircraft Spruce quickly resolved the issue with little effort on my part. The customer service rep that I spoke to was very nice and efficient. Because of dealings with other companies I was wary, but AS was great to deal with.

Q&A

Q: I have Tempest UREM40E in my Super Cub and want to convert to fine wire plugs. What is the proper part number?

If you are sticking with Tempest, you will need P/N# 08-01234 (TEMPEST SPARK PLUG UREM38S XL). If you are switching to Champion, you will need part # REM38S, CHAMPION SPARK PLUG REM38S.

Q: Is there a fine wire replacement spark plug for a Champion REM40E?

Yes, the REM38S is the fine wire replacement for the REM40E.

Q: Did you accidentally make a mistake in the first question of this q&a. I cannot find a UREM38S XL. Please let me know if Im just not finding it. Thank you

Use our Part# 08-01234 or UREM38S. You will be able to pull it up without the XL.
