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.

I ordered two of the same sparkplugs , when I checked them, one of them had a gap a little tighter than I wanted , I was able to adjust but it would be easier to close a larger gap than one you want to open . Thanks Joe

  • BY (Electrode Design) = Twin Electrodes Nickel (B) and Projected Core Nose (Y)
REM40E:
  • R (Resistor) = Mil-Spec. Resistor-Erosion protection
  • E (Barrel Style) = Shielded 5/8"-24 Thread
  • M (Mounting Thread/Reach/Hex Size)= 18mm, 1/2" 1.27cm, 7/8" 2.22cm
