NGK 6482 Spark Plug

NGK Iridium IX Spark Plug 6482 Overview

The NGK Iridium IX Spark Plug 6482 is built for drivers who want precise ignition performance and OE-style reliability. With an iridium center electrode, copper core, and a 5,000 ohm resistor, this plug supports consistent spark delivery in a wide range of gasoline engines.

As part of the NGK Iridium IX Spark Plug line, this plug uses a fine-wire iridium tip and a taper-cut ground electrode design to promote efficient combustion and stable firing. It is a strong choice for routine maintenance on vehicles such as Honda Civic and Toyota Corolla applications that call for this style of NGK spark plug.

Key Features

• NGK Iridium IX Spark Plug line for performance-focused ignition service
• Iridium center electrode tip material for durable spark delivery
• Copper core center electrode for heat transfer support
• Taper-cut ground electrode tip design with standard ground configuration
• 5,000 ohm resistance for ignition system compatibility
• Pre-gapped at .032 for direct service use
• Flat seat design, 10 mm thread diameter, .75 reach, and 5/8 hex size
• Removable nut terminal type for common ignition wire and coil-on-plug setups

Detailed Description

NGK part number 6482, also identified as CR10EIX, is engineered for applications that specify a 10 heat range spark plug with a flat seat and 10 mm thread diameter. The iridium tip helps maintain a stable spark over extended service intervals, while the nickel ground electrode and taper-cut profile support efficient flame initiation. This plug is designed for engines that require a .032 pre-gap and a removable nut terminal, making it a practical replacement for many import and domestic ignition systems. If you are servicing a Honda Civic or Toyota Corolla and need NGK 6482, this spark plug delivers the specifications technicians look for in a direct replacement ignition component.

NGK has decades of OE supply experience and manufactures spark plugs for automotive, motorcycle, marine, and small engine use. That background shows in the dimensional accuracy and material selection of this plug, which is built to meet original equipment standards for durability and operational performance.

This part cross-references DENSO Auto Parts (e.g., 5364, 5367) for the same application.

What It Helps Address

• Engine misfire caused by worn or fouled spark plugs
• Hard starting from weak or inconsistent ignition output
• Rough idle related to degraded spark quality
• Reduced throttle response from inefficient combustion
• Maintenance replacement for vehicles calling for NGK 6482 or CR10EIX

Installation Notes and Tips

Verify the required thread diameter, reach, seat type, and heat range before installation. Confirm the gap specification against the engine service information; this plug is pre-gapped at .032, but final verification is still recommended. Use proper torque procedures for flat-seat spark plugs and inspect ignition wires or coil boots for wear before installing the new plug. For Honda Civic and Toyota Corolla service, match the OE-style specification exactly to avoid drivability issues.

Quality Assurance

NGK is a long-standing OE spark plug supplier with broad North American coverage and manufacturing experience across multiple engine categories. Part number 6482 is produced to support original equipment standards for durability and consistent ignition performance.
