Universal Spark plug HT cap, rubber type, NGK/MB

Probably the best HT cap on the market, reliable and water proof and doesnt pop off.

Supplies of these NGK rubber caps have been hard to get and prices were soaring, so we had them made to the same design and quality.

Marked with MB the sign of quality.

Made with heat resistant Silicone.

These come in Black and uses the little screw on cap on the spark plug making the cap much more reliable so it doesnt keep popping off and wearing the spark plug out.

5 ohm resistor rated so works with digital toys.
