Product Line Details
Denso’s U-Groove Conventional line focuses on reliable spark formation with a ground electrode shape that exposes more of the flame kernel area. That design supports consistent ignition performance in engines that call for a standard-style spark plug, including many Ford Mustang, Ford Explorer, and Chevrolet Express applications. The Denso 5023 is also listed under interchange reference T16EPR-U15.
Detailed Description
The Denso 5023 spark plug is designed for drivers who need a conventional replacement with OE-style dimensions and ignition characteristics. The U-Groove ground electrode helps create a more efficient spark path, while the copper core center electrode supports heat transfer and steady performance under normal operating conditions. This makes it a practical service part for a broad range of older and newer vehicles across Ford, GM, Mazda, Lincoln, Mercury, Buick, Cadillac, Pontiac, Jaguar, and GMC platforms.

What It Helps Address
- Hard starting caused by worn or inconsistent spark plugs
- Rough idle from weak ignition performance
- Misfire conditions related to aged secondary ignition components
- Reduced throttle response from degraded spark delivery
- Maintenance replacement for high-mileage ignition service
Installation Notes and Tips
Verify thread diameter, reach, seat type, and heat range before installation. The Denso 5023 uses a tapered seat and 14 mm thread diameter, so it should be matched to the engine specification exactly. Check the pre-gap against the vehicle service information before installing, and inspect ignition wires or coil-on-plug components at the same time to avoid repeat misfire concerns.
Quality Assurance
This spark plug is built by Denso, a major ignition component manufacturer with OE-level application coverage across many domestic and import vehicles. The part is engineered to meet the dimensional and performance requirements listed above for direct replacement use.
