Mk Spark Plug
- Heavy-duty nickel center electrode ensures longer life than standard copper plugs
- Copper core provides better heat transfer for resistance to pre-ignition and fouling
- Metal glass fused resistor maximizes interference suppression
- Ribbed insulator design prevents misfire due to current leakage
- Nickel-plated rolled threads provide superior resistance to corrosion and do not require anti-seize
