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.

Had a little roughness and had to clean the plugs often on one mag. I replaced all 4 bottom plugs with REM38S and the problem is gone. Highly recommend these as a replacement for standard plugs.
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.
