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.
