A resistor spark plug is a type of spark plug designed with an integrated electrical resistor that reduces electromagnetic interference (EMI) and radio frequency interference (RFI) generated during the ignition process.
Resistor spark plugs optimize engine performance by igniting the air-fuel mixture within the combustion chamber of an internal combustion engine.
They initiate the combustion process that powers our vehicles by generating a controlled spark. Resistor spark plugs are unlike the conventional spark plugs because they’re designed with a built-in resistance element.
Advantages of using resistor spark plugs include reduction of electrical interference, they minimize radio frequency noise, and enhance overall ignition performance.
Resistor spark plugs vs non-resistor spark plug.
The differences between resistor spark plugs and non-resistor spark plugs depend on how they impact engine performance, fuel efficiency, and their compatibility with various ignition systems.
Key differences between resistor and non-resistor spark plugs.
The key differences between resistor and non-resistor spark plugs include their resistance levels, their construction and electrode design.
