Common Uses

Restoring ignition performance on classic Chevrolet C10 and GMC Jimmy trucks
Replacing worn plugs that cause rough idle or misfire conditions
Addressing hard starting in older HEI-equipped GM vehicles
Maintaining proper spark output in California-emissions applications
Servicing vintage GM cars and vans with OE-style plug specifications

Installation Notes and Tips

Verify the vehicle’s required plug specification before installation, including thread diameter, reach, seat type, and gap. NGK 7240 is supplied with a 0.060 in. pre-gap, but the gap should still be checked against the engine’s service requirements before use. Use the correct spark plug socket for the 5/8 in. hex and confirm the electrical terminal style matches the ignition lead or boot.

For best results, install on a cool engine and follow the manufacturer’s torque specification for the cylinder head material. This helps protect the tapered seat and supports consistent sealing in Chevrolet C10, K5 Blazer, GMC Jimmy, and other listed applications.

NGK is a long-established OE supplier and spark plug manufacturer with North American production, inventory, and distribution support. The brand’s OE-focused engineering and broad vehicle coverage are reflected in the construction of NGK 7240, which is built to original-equipment standards for listed applications.
