No, Using a resistor spark plug with resistor wires can create too much resistance for the ignition system.
The "X" in the Champion XC12YC spark plug designation indicates that it is designed for extended service or has a specific feature tailored for certain engines, often related to the plug's heat range or performance characteristics. Additionally, the "X" can sometimes signify a specific design or construction feature that differentiates it from other models in the Champion lineup.
The primary difference between XC12YC and RC12YC spark plugs lies in their construction and intended application. The XC12YC spark plug is designed for extended service intervals and typically has a longer insulator, offering better heat dissipation. In contrast, the RC12YC is a standard spark plug more commonly used in various engines and may have a shorter lifespan. Both plugs are designed for specific engine types, so it's essential to use the one recommended for your vehicle.
Resistor
Sometimes a resistor is installed in spark plug wire as a supressor to reduce radio static interference
you can just use a j4c without a resistor
It should be at 0.O25 on standard spark plugs and O.O35 on resistor on resistor spark plugs.
an rc8j resistor or a cj8y
the R stands for Resistor. It is a resistor plug.
The B&S 797235 is a resistor plug. You can use a Champion RC12YC.
Check the plug No. Last number is for the Gap size. NGK Resistor Spark Plug DPR7EA-9 The 9 is the gap size
rc is a taller electrode plug physically so im stumped ?? and has taller and different center electrode than "QC" may interfere combustion cycles. maybe not enough tech data on these forums
