Version: Short Reach

The high performance, electronic ignition, has demonstrated it’s reliability, easy starts, greater power at altitude, and leaner, more efficient combustion. Yet your expensive aircraft Spark Plugs, can prevent the pilot from taking full advantage or this electronic powerhouse. The S.5 is a precision CNC adapter, that installs easily in aircraft engines, that use 18mm “short reach” spark plugs, transforming the 18mm threaded hole down to 14mm.

• High performance 14mm automotive/ motorcycle spark plugs, that offer an almost unlimited variety of heat ranges, & electrode styles, designed specifically to take advantage of electronic ignitions.

• Shorter plugs with 90° silicon boots, give greater clearance for sleeker cowls and less drag, meaning higher speed, using less power.

• Precious and semi precious metal racing spark plugs (the ultimate in reliability and long life) for less than you’d pay for ordinary aircraf plugs. More speed, power, efficiency, as well as a cost savings each time you change spark plugs.

• New & improved corrosion resistant design substantially extends the operational life of the S.5 Spark Plug Adapter.
