Product details
The Lycoming Electronic Ignition System (EIS), part number 66K4F3SN-01, is a solid-state electronic ignition unit configured for a 4-cylinder Lycoming engine impulse-coupled magneto position with fixed 20° timing.
Designed by Lycoming as a drop-in-capable magneto replacement, the EIS has no moving parts and is intended to reduce scheduled maintenance compared with a conventional magneto. The 66K4F configuration is designed to use the existing magneto-to-engine drive interface, existing aviation spark plugs set to OEM specifications, and a Slick-style ignition harness.
