E-Mag Long Reach Plug Adapter 4Pk With Copper Gaskets

High performance electronic ignitions have demonstrated reliability, easier starting, greater power at altitude, and more efficient combustion. Auto plug adapters allow for an easy conversion of 18mm (standard engine plug thread) to 14mm (common auto plug thread). Both short reach and long reach adapters are available.

The Spark Plug Adapter allows you to use:

High performance 14mm automotive plugs, that offer an almost unlimited variety of heat ranges, & electrode styles, designed specifically to take advantage of electronic ignitions. See ignition manufacturer documentation for recommendations
Note: not all plugs are equally suited.

Shorter plugs with 90° silicon boots provides greater clearance for sleeker cowls and less drag.

Precious and semi precious metal racing spark plugs (the ultimate in reliability and long life). More speed, power, efficiency, as well as a cost savings each time you change spark plugs.

Some kits also include 4 adapter gaskets - see kit description.
