Engineered for Daily Reliability

The NGK DCPR7E features a standard nickel-alloy outer electrode structurally paired with a 98% pure copper core. This design maximizes heat dissipation, dramatically reducing the risk of engine-damaging pre-ignition and hot spots during heavy bumper-to-bumper city idling. Equipped with a built-in 5 kOhm resistor, it suppresses electrical noise and radio-frequency interference (RFI) to safeguard sensitive onboard electronic systems. Finished with NGK’s signature trivalent metal plating, the threads provide outstanding protection against corrosion and seizing over a long service life.
