10 mm to 1/4-32 mm Spark Plug Adapter for 1/4-32 Spark Plugs
30 in stock
This Adapter allows you change the 10 x 1 mm threads to 1/4-32 threads (same as GLOW Plugs threads) and use NGK-ME8, RCexl 1/4-32 or RimFire VR2 Spark Plugs. This will give you a lower profile engine and fit better under the Cowling.
The Adapter is made from STEEL and offers better strength than the brass that break off easier.
Please keep in mind that even tho is Steel please tight with care the material is still thin and can break off.
Use some HI TEMP Thread lock of JB Weld when you insert them .
In case of breaking use an easy-out to take it OFF.
