Electroair – Bendix Single Drive, Dual Mag (Siamese Mag)

The ElectroAir Electronic Ignition Kit is a fully STC’d kit for most Lycoming and Continental engines.

Replacing a Siamese magneto with the EIS kit will typically improve fuel economy on average by 10-15% (some customers 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 (it’s is a rotating part with bearings) and spark plug wires on condition. This kit can be used on either 12V or 24V systems.

BENEFITS: This system is best paired up with an engine monitor system to get the maximum fuel economy and performance from your engine by utilizing the “lean assist” function. Magneto 500-hour checks are very expensive when following the manufacturer recommended inspection procedures. This waste spark system means cleaner plugs that last a lot longer so less 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 like traditional magneto points or cam when 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 some going up to 3000hrs TSOH when flying more than 100hrs a year along with oil analysis monitoring. Combined with improved fuel economy, this pays for itself!

You can choose between fine wire spark plugs or massive electrode spark plugs. Fine wire plugs are more expensive but are less prone to fouling and perform a little better due to a more confined spark path.
