Part: Honda CB550K / CB550F / CB500K Spark Plug Boots - Sold In Pairs
Why You Need This: Quite often the connection between the wire and boot are the root cause of ignition problems. Fresh NGK spark plug boots made in Japan are a excellent replacement for the original plug boots. These Honda CB550K / CB550F / CB500K Spark Plug Boots feature a water resistant seal and come in two sizes.
Either size fits all four cylinders, but we have found that using the long boots on the inner two cylinders (2&3) and the short boots on the outer cylinders (1&4). While you're in there you might as well swap the spark plugs.
Installation Tip: Trim away about 1/4" of old wire from the end of the plug wire to grab some fresh wire. Screw the boots into the end of the wires, press and turn clockwise until roughly 1/2" of wire is in the boot.
