FAQ
Why are these spark plugs superior in performance?
They feature an "ultra wide heat range" design with a copper core inserted deeply in the center electrode to dissipate heat quickly, resisting both overheating and fouling.
What materials are used for insulation?
The insulator is made of state-of-the-art high-alumina ceramics, providing superior thermal conductivity, mechanical strength, and insulation at high temperatures.
What is the function of the ribs on the insulator?
The ribs extend the surface distance to prevent flash-over (sparking between the terminal and metal shell), ensuring the spark remains at the correct gap.
What is a resistor spark plug?
It incorporates a ceramic resistor to suppress ignition noise, preventing electrical interference with car radios, phones, and engine computers.
How does the V-grooved type center electrode help?
It features a 90°V-groove that directs the spark to the edges, improving ignitability because the electrodes interfere less with the growing flame core.
How do you ensure gas-tightness?
We use a special hot crimping process to ensure a solid construction and superior gas-tightness for reliable engine operation.
