This NGK TR6 V-Power Spark Plug Set includes eight NGK 4177 spark plugs for compatible 2000–2009 Chevrolet Tahoe models equipped with the 4.8L V8 engine.
NGK V-Power spark plugs use a V-groove nickel center electrode designed to direct the spark toward the edge of the electrode, helping improve ignitability and reduce quenching. The TR6 uses a copper-core center electrode, tapered seat, 14mm thread, and NGK heat range 6.

V-Power Electrode Design
NGK's V-Power design uses a V-groove in the center electrode to move the spark toward the electrode edge. This helps the spark develop in an area with better exposure to the air/fuel mixture for improved ignitability.
Recommended Use

- Performance-oriented 4.8L V8 builds where NGK TR6 is the desired plug
- Tuned or modified applications where NGK heat range 6 is appropriate

Installation Note
Confirm the required spark plug gap for your specific engine setup before installation. Modified, boosted, or tuned engines may require a different plug gap than a stock application. Install spark plugs using the proper torque specification for the engine.
