Part: Honda CB350 / CB360/ CB450 Spark Plug NGK BR8ES - Sold Individually
Why You Need This: It s amazing how many different types of spark plugs I see in old Honda engines, platinum, extra hot, extra cold, two different brands in one bike. Just because it fits the head does not mean that it is the right spark plug. The NGK BR8ES is the original specified copper core spark plugs for the CL350 Scrambler / S350L / CB350, CL360 / CJ360 / CB360 and CL450 / CB450 / CB500T engines. If you are doing some carburetor tuning get a few sets to read the color based on fuel mixture. If you are using an ignition rebuild kit, then these will finish the job off. Sold individually, two are needed per bike.
UPDATE: As of January 2020, NGK has discontinued the B8ES and superseded with the BR8ES. The BR8ES is a resistor plug, which is designed to reduce electromagnetic interference of ignition systems for things like radios and phones while used in automotive applications. It is the new replacement plug for our vintage Honda motorcycles and performs just like the older B8ES spark plug. More info about resistor plugs can be found on the NGK FAQ page.
Installation Tip: Unscrew the terminal stud on top of the plug to expose the threads. Gap the plugs to .030", use a dab of light oil on the threads, and tighten till snug.
