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.

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.

Had 2 sets of new Tempest plugs, in a new engine, fail. Changed to Champion and no more problems. Definitely worth the $6 dollars more.
Champion is Champion, we use this Plugs for more than 40 years in our Piper Pawnees, they run more than 1000 hours a year, under very hot climate conditions in Colombia (SA)
these are a very good product for the money. I run these in a cessna 150 with a lycombing o-320. we put more than 300 hours a year on the plugs. still going stronge
I bought 4 and the standard spark plug socket does not fit them.
There is no difference in the applications of UREM40E and REM40E. They are the same spark plug manufactured by different companies. Tempest makes the UREM40E and Champion makes the REM40E.
Yes, each plug will include a copper gasket.
