The main difference between Champion CJ8 and CJ8Y spark plugs lies in their design and intended application. The CJ8 is a standard spark plug suitable for a variety of engines, while the CJ8Y features a longer reach and a different heat range, making it more suitable for specific engine requirements, particularly in some two-stroke applications. Additionally, the CJ8Y may have variations in electrode design or material, which can affect performance and longevity. Always consult your engine's specifications to choose the correct plug.
The main difference between the Champion CJ8Y and CJ7Y spark plugs lies in their heat range and design specifications. The CJ8Y has a higher heat range, making it suitable for engines that operate at higher temperatures or require a longer plug life, while the CJ7Y is designed for standard applications with a lower heat range. This means the CJ8Y can handle more demanding conditions without fouling, whereas the CJ7Y is typically used in engines with less thermal stress. Always consult the engine manufacturer's specifications to determine the appropriate spark plug for your specific application.
NGK BPM6A
Champion CJ8Y
A Champion CJ8Y or J19LM will perform fine
Mine has original plug, it is a: Champion # CJ8Y
Yes you can use a CJ8 for a CJ8Y, but you cannot use a CJ8Y for a CJ8......the CJ8Y has about 1/4in more thread.
B&S sparkplug # 801254 crosses over to Champion CJ8Y or NGK BRMR4A>
Cj8y
In place of the JENN FENG 9295-331501, I am successfully using a NGK (7021) BPM6A sparkplug; Which is cross referenced to two Champion plugs CHAMPION CJ8Y or CJ7Y
an rc8j resistor or a cj8y
rcj8y has a built in resistor to protect electronic ignitions from spurious signals also to reduce interference to TVs etc. i.e. the R in the plug designation indicates resistor.
Yes, you can use CJ8Y plugs instead of BPM8Y plugs, as they are generally compatible and have similar specifications. However, it's essential to check the specific requirements of your engine, as some may have different heat ranges or designs that could affect performance. Always refer to the manufacturer's recommendations for the best results.
