New spark plug resistor cover replaces NGK's now discontinued SB05F. This one is a straight 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 any bike as long as you have 7mm spark plug wires and enough clearance. Overall length 3.7" (94mm) with rubber attached.
- For use with 7mm diameter plug wires
- Sold Individually
Replaces NGK Part Number: 8080
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.
Fits tons of bikes and many models used more than 1 type of cap. Check the part number and photo to see if it's what you need.
