Product Description

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).

E-MAG auto plug adapter kits convert the 18mm aircraft spark plug bore in Lycoming and Continental experimental engines to accept standard 14mm automotive spark plugs. Aircraft engines are manufactured with either Short Reach (SR, ~1/2" thread depth) or Long Reach (LR, ~3/4" thread depth) cylinder bores, select the correct kit to match your engine.

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.
  • Thread depth can also be measured directly in the cylinder

Installation Note: Always install the spark plug into the adapter first (finger-tight and fully seated), then install the combined assembly into the engine. Torque to 18 ft/lb through the spark plug only, do NOT torque the adapter directly. Use anti-seize sparingly on the engine-side threads only.

FAQs

What is a good core return?

A good core retunr for a factory overhauled Slick Magneto is going to be a current series 4300 or 6300 Slick Magneto. If a new Slick Magneto is purchased, then older series Slick Magnetos can be considered for credit on a case by case basis. 

Does this Magneto come with an impulse?

Check the "Detail" tab of the Slick Magneto that you are interested in buying and the Slick Magneto listed with a "Type: Impulsed" will come up with an impulse coupling.

What are the possible bill backs that I can get on a core return for my Slick Magneto?

There are no bill backs on a core return that is a current series 4300 or 6300 Slick Magneto. 

For a Slick Magneto what is the service time?

According to the Slick Magneto by Champion Overhaul Manual L-1363F, the magneto should be overhauled at TBO, lighting strike, prop strike, sudden stoppage of the engine and immersion of the aircraft.
