E-Magnetos

The E-MAG series electronic ignition systems provide a direct replacement for traditional magnetos on Lycoming and Continental 4- and 6-cylinder experimental engines. Featuring high-energy electronic ignition, variable spark timing, and self-powered internal alternators, E-MAG systems deliver smoother operation, improved fuel efficiency, easier starting, and added reliability.

Available in both variable-timing and fixed-timing configurations, each model is designed for straightforward installation with built-in LED/tone guided timing setup and no special tools required. Across the lineup, E-MAG brings modern ignition performance and dependable self-powered operation to experimental aircraft engines.

E-Magneto Adapter Kits

EMAG Auto Spark Plug Adapter Bundles

Adapter kits convert the standard 18mm aircraft spark plug thread in your cylinders to accept 14mm automotive-style spark plugs for use with the E-MAG ignition system. Must match your cylinder thread depth (Short Reach or Long Reach).

To identify your cylinder thread depth:

• Short Reach (SR): Aircraft plug call-out contains the letter "M" (e.g., REM series). SR adapters reduce 18mm to 14mm thread for short reach (19mm) auto plugs (NGK BR8ES or BR8EIX).
• Long Reach (LR/LRX): Aircraft plug call-out contains the letter "B" (e.g., REB series). LR adapters reduce 18mm to 14mm thread for long reach (26.5mm) auto plugs (Denso IKH27). LRX adapters are the same as LR except the hex head is extended to better fit certain Continental (six cylinder) heads where the plug insertion face is recessed.
• Cylinder thread depth can also be measured directly. Short Reach (“SR”) adapters have external thread length of approximately 1/2”. Long Reach (“LR”) adapters have external thread length of approximately 3/4”.
