Spark Plug NGK DIFR6C11 (1312)

The NGK DIFR6C11 Iridium spark plug (Stock No. 1312) is engineered for modern engines demanding high ignition stability and long-term durability. This model features an iridium-tipped center electrode and a platinum chip on the ground electrode, providing superior resistance to spark erosion. The fine electrode diameter reduces the required ignition voltage, facilitating cold starts and enhancing engine responsiveness. With a heat range of 6 and an integrated resistor, it ensures optimal heat dissipation and protects vehicle electronics from interference. These plugs offer an extended service life of up to 100,000 km and contribute to fuel efficiency through more complete combustion. The high corrosion resistance of the metal shell ensures easy removal even after prolonged use.
