Amongst the myriad of spark plugs that can fit into old Honda engines, it's essential to pick the right one. Suboptimal or mismatched plugs, like platinum or those with varying temperature grades, can lead to compromised engine performance. The NGK BR8ES, with its copper core, was tailor-made for the CL350 Scrambler / SL350 / CB350, CL360 / CJ360 / CB360, and CL450 / CB450 / CB500T engines. It ensures optimal combustion and performance. If you're into carburetor tuning, stock up on these plugs to effectively gauge fuel mixture readings. Also, if you're wrapping up with an ignition rebuild, the NGK BR8ES is the perfect finishing touch.
As of January 2020, NGK has transitioned from the B8ES model to its successor - the BR8ES. The latter is a resistor plug, designed primarily to curb electromagnetic interference in ignition systems. This is essential for modern devices like radios and phones. Despite its modern design attributes, the BR8ES remains true to the performance legacy of its predecessor for vintage Honda motorcycles. Learn more about the resistor plugs on the official NGK FAQ page.
