Denso 5062 Spark Plug

Denso 5062 U-Groove Conventional Spark Plug

The Denso 5062 spark plug is an OEM-specified ignition component built around a special ground electrode configuration. It uses a multi-electrode design with a copper core center electrode and nickel tip materials to support stable secondary ignition performance in the correct application.

For Porsche ignition service and other OE-matched applications, this Denso spark plug combines a 14.00 mm thread diameter, 19.00 mm reach, flat seat, and 0.9 pre-gap size. The Denso 5062 is part of the U-Groove Conventional line, which focuses on conventional spark plug construction with OE-style electrode geometry.

Detailed Description

Denso 5062 is a conventional spark plug engineered to match OE-style ignition requirements where the original application calls for a special ground electrode layout. The multi-electrode configuration is paired with nickel ground and center tip materials, while the copper core center electrode supports consistent spark delivery in the specified engine setup. This part cross-references Denso Auto Parts K22PBR-S for the same application.

Vehicle searchers looking for a Porsche spark plug, Denso 5062 spark plug, or an OE-style replacement for Porsche ignition service can use this part number when the application calls for the listed dimensions and electrode design. Porsche 999 170 182 90 and Porsche 999 170 183 90 are listed interchange references for this spark plug.

What It Is Used For

• Replacing a worn spark plug that no longer maintains consistent ignition
• Addressing rough idle caused by degraded plug electrodes
• Restoring proper spark delivery in OE-specified Porsche ignition applications
• Correcting misfire conditions related to plug wear or incorrect gap
• Supporting reliable combustion when the original plug uses a multi-electrode layout

Installation Notes and Tips

Verify the thread diameter, reach, seat type, heat range, and pre-gap size against the vehicle service specification before installation. Use the correct torque procedure for the cylinder head material and confirm the ignition system is in good condition so the new plug can operate as intended. For Porsche applications, match the OE reference and engine specification before replacing the spark plug.

Quality Assurance

Denso manufactures this spark plug to OE-style specifications with the electrode configuration and dimensions called out for the application. The U-Groove Conventional line reflects Denso’s conventional spark plug construction for vehicles that require a standard replacement with OEM-matched geometry.
