Estimated savings by switching to ElectroAir Ignition System

  • Based on Engine TBO of 1800hrs

  • Magneto $750/500hrs = $1.50/hour

  • Labor per 100hrs to inspect/adjust as needed $95x1hr= $.95/hr

  • Fuel savings estimate 2 gph x $4.50/gal=$9.00/hr

Estimated savings over life of engine 

$11.45/hr x 1800TBO = $20,610!


The ElectroAir Electronic Ignition Kit is a fully STC'd kit for most Lycoming and Continental engines. Replacing one magneto with the EIS kit will typically improve fuel economy on average by 10-15% (some have reported higher). Additionally, there will be an improvement in hot starts, increase in horsepower, smoother engine operation, noticeable throttle response (especially on last minute go arounds) and improved high altitude performance. ElectroAir's EIS is the only STC'd electronic ignition system on the market that adjusts spark timing automatically as you change power settings and altitude to maintain the optimum performance and fuel efficiency out of your engine without any damage or significant weight change. This is completed by way of our MAP Sensor - timing is adjusted based on manifold pressure and altitude. Most parts on the EIS system are not life limited but the MTH is recommended to be changed at overhaul of the engine (its is a moving part) and spark plug wires on a regular interval or condition. This kit can be used on either 12V or 24V systems.

BENEFITS: This system is best paired up with a engine monitor system to get the maximum fuel economy and performance from your engine. Magnetos cost $750 or more every 500hrs when following the manufacture recommended inspection procedures to replace the internal coil, points, and bearings not counting labor to remove, ship, & install them. Our waste spark system means cleaner plugs that last a lot longer so no 50hr spark plug cleaning or premature replacement. Being a fixed component, you set it and forget it so no repetitive mag timing checks or adjustments are needed as magneto points or cam wear starts setting in. Running cleaner means the engine performs better so the engine can run longer without issues. Some customers have reported running past TBO with oil analysis monitoring. Combined with improved fuel economy, this pays for itself! 


Kit includes: all the required parts to replace the magneto (typically, the right hand mag) in most 4cyl Lycoming engines. 2 circuit breakers are required for this system. A new switch panel is recommended but not required. You can choose between fine wire spark plugs or massive electrode spark plugs.
