NGK Spark Plug Resistor Cover - 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.
- NGK spark plug resistor covers are the best protection against radio frequency interference
- 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
- Sold Individually
NGK Part Number: 8072
Replaced 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.
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.

Just what my bike needed
These work great on my CB650. New wires and caps have made a real difference in starting up my bike. Nice, secure fit and great performance from a trusted brand.

Perfect fit
My cb350f fires right up and runs great. The NGK resistor covers fit snug like OEM and installation on the new coil packs was easy.

Great Replacement
These NGK Resistors are very nice and worked perfectly on my CB350F. Since I had to replace the coils, I felt it proper to replace the resistors too.

102 degree spark plug cap
Haven't installed the cap yet, but, upon initial inspection, the cap is of excellent manufacture and I'm sure it will perform as advertised

Great product, better fit
There are some caveats living in SF as a CB owner when parking your bike on the street. Occasionally, you will come out in the morning and will find one of your spark plugs missing (apparently great for smashing windows). This has happened to me 5-6 times already. Well, the "thieves" never thought to gently pull the spark plug cap when taking my plugs so over time I was losing contact in the plug without realizing it resulting in a fried Dyna S ignition. To make a longer story short, I needed to replace my my wires and caps too and these were perfect. They seem to be very well constructed and I can't imagine the resistor contacts within the cap ever breaking even if it was ran over by a semi. Great product, fits perfectly, and would highly recommend!
