Set of 4 new spark plug resistor covers replaces NGK's now discontinued XD05F for the Honda CB650 and GL1100/1200, see fitment list below. 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 any bike as long as you have 7mm spark plug wires and enough clearance.
- 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
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.
