Denso 3192 Spark Plug

Denso 3192 Spark Plug Overview

Denso 3192 is a U-Groove conventional spark plug built for direct ignition service in a wide range of Honda, Acura, Nissan, Mazda, and INFINITI applications. Its U-groove ground electrode design is engineered to improve ignitability, helping support more efficient combustion and consistent engine operation.

This Denso U-Groove Conventional spark plug uses a copper center electrode core, nickel center electrode tip, nickel ground electrode tip, and a standard ground configuration. It also features a 5,000-ohm resistor, a 1.1 pre-gap size, a flat seat, a 14.00 mm thread diameter, a 19.00 mm reach, and a 16.0 mm hex size.

Key Features

• U-Groove ground electrode design for improved spark exposure
• Conventional spark plug construction for OE-style service replacement
• Copper core center electrode for stable conductivity
• Nickel electrode materials for durable everyday ignition use
• 5,000-ohm resistance for radio noise suppression
• Flat seat design with 14.00 mm thread diameter and 19.00 mm reach
• Pre-gapped at 1.1 for specified applications

Detailed Product Description

The Denso U-Groove Conventional line focuses on practical ignition performance for vehicles that call for a standard spark plug design. On part number 3192, the U-shaped ground electrode helps expose the spark kernel more effectively than a basic flat-ground layout, which can support cleaner combustion and smoother engine response in the correct application. This part number 3192 is a direct-fit style spark plug for select Honda Civic, Honda S2000, Acura RSX, Nissan Frontier, Nissan Xterra, and other listed applications.

Cross-reference part numbers include DENSO Auto Parts K22PR-U11 and Mazda 0000-18-BP03 for the same application.

Installation Notes and Tips

Verify the engine application against the listed fitment before installation. Confirm the specified thread diameter, reach, seat type, and pre-gap size match the vehicle requirements, and inspect the ignition system for wear before installing new plugs. Use proper torque procedures for the cylinder head material and application.

Quality Assurance

Denso manufactures this spark plug as part of its U-Groove Conventional product line, which is built around a conventional replacement format with a U-groove electrode profile for improved ignitability in the correct engine application.
