Air Boss® Dual Mag Ignition Harnesses
for Lycoming Engines

The Air Boss® dual magneto ignition harnesses incorporate a negative-pitch spring design allowing the coil spring tip to lie flat against the spark plug electrode. The tinned-copper, nickel plated braid shielding greatly reduces EMI, and the extremely flexible stainless steel wire provides optimum wire conductivity. The abrasion resistant, Air Boss® gold, polymer cover has been engineered specifically for the high-temperature environment of aircraft engines. Air Boss® – the brand dedicated to bringing quality and affordability to general aviation.
