We will buy back your old working or non working mag for 150.00

The EIS-41000 Electronic Ignition Kit is a fully STC'd kit for most Lycoming 4cyl engines. Replacing one magneto with the EIS-41000 will typically improve fuel economy on average by 10-15% (many operators have reported consistent fuel savings of 1gph or greater). Additionally, there will be an improvement in horsepower, smoother engine operation, and improved high altitude performance. The EIS-41000 adjusts spark timing automatically by way of our MAP Sensor - timing is adjusted with altitude. Most parts on the EIS-41000 are not life limited (the MTH is recommended to be changed at overhaul of the engine; spark plug wires on a regular interval) - this combined with reduced spark plug fouling means lower maintenance costs. This kit can be used on either 12V or 24V systems.

Kit includes: all the required parts to replace the direct drive magneto (typically, the right hand mag) in most 4cyl Lycoming engines. (Please refer to the eligibility schedule to verify the system can be installed on your engine - Note: engines are being added regularly).
