Set of 4 new spark plug resistor covers replaces NGK's now discontinued XD05F. This one has a 102 degree bend, long style. For 12mm or 10mm thread spark plugs without the terminal nut. We recommend using non-resistor type spark plugs when using resistor caps on vintage Honda's.

Fits all Honda SOHC Fours.

Rubber waterproof boots to seal out the elements, so the engine won't cut out if it rains.

For use with 7mm diameter plug wires

Includes: 120 Degree x2 and 102 Degree x2

Replaces NGK Part Number: 8072
Replaces Honda Part: 30700-MC8-000

Installation tips:

Remove terminal nut before installing new spark plugs. It's screwed onto the top of the spark plug.
Put a light coating of anti-seize on the spark plug threading before installing. After all, you're threading a steel part into a aluminum engine case.
Don't over tighten the spark plug, 1/8 to 1/4 turn past finger tight.
When using the old spark plug wires, trim them back 1/4" - 1/2" to expose fresh wire, then using a pick type tool, fan out the wires before threading on the new resistor cover.
Twist on the new cover about 3 full turns and give it a tug to make sure it's snug.

We also carry spark plugs for the models below. (not included)

Installation Tip: Fan out the spark plug wires before twisting on the caps that way you make a better connection.
