Denso 5022 U-Groove Spark Plug Overview

The Denso 5022 is a conventional spark plug built for direct-fit service in a wide range of Ford, Mercury, GM, Cadillac, Mercedes-Benz, Mazda, Buick, Chevrolet, Oldsmobile, and Pontiac applications. Its U-Groove electrode design is engineered to improve ignitability, helping the engine light the air-fuel mixture more consistently for smoother operation and better efficiency.

For shoppers searching for a Denso 5022 spark plug for Ford Ranger, Mercury Milan, or Mercedes-Benz 300E applications, this part combines OE-style dimensions with a conventional copper-core construction and nickel electrode materials.

  • U-Groove ground electrode design for improved ignitability
  • Conventional spark plug construction for broad vehicle coverage
  • Copper center electrode core for stable heat transfer
  • Nickel center and ground electrode tip materials
  • 5000 ohm resistance
  • Pre-gapped to 0.8 mm
  • Tapered seat design
  • 14.00 mm thread diameter, 18.00 mm reach, 16.0 mm hex size

Product Line Details

Denso’s U-Groove Conventional line focuses on dependable ignition performance with a design that exposes more of the spark kernel to the air-fuel charge. That approach supports consistent combustion in everyday driving and makes the Denso 5022 a practical replacement choice for older and late-model vehicles that specify a conventional plug.

Fitment and Cross References

Compatible with applications such as 2011-2012 Ford Fusion, 2011 Mercury Milan, 2003-2010 Ford Ranger, 2004-2007 Cadillac SRX, 2005-2006 Cadillac STS, 2004-2006 Cadillac XLR, 2004-2005 Mazda B4000, and 1986-1993 Mercedes-Benz 300E. This part cross-references DENSO Auto Parts T16EPR-U and Ford AWSF42C for the same application.

What It Helps Address

  • Hard starting caused by worn spark plugs
  • Rough idle from weak or inconsistent spark
  • Misfire conditions related to aged ignition components
  • Reduced fuel efficiency from incomplete combustion
  • Loss of throttle response in high-mileage ignition systems

Installation Notes and Tips

Verify thread diameter, reach, seat type, and heat range before installation. The Denso 5022 uses a tapered seat, 14.00 mm thread diameter, 18.00 mm reach, and 16.0 mm hex size, so matching the engine specification is essential. Check the gap against the vehicle service information before installation, even though the plug is pre-gapped to 0.8 mm.

Quality Assurance

Denso manufactures this spark plug to OE-style dimensional standards for listed applications, with nickel and copper materials selected for consistent ignition service in conventional secondary ignition systems.
