Iridium Power Line Details
Denso Iridium Power focuses on fine-wire electrode construction for responsive ignition performance and stable spark characteristics. This spark plug 5380 uses Denso’s small-diameter iridium center electrode to help maintain a concentrated spark point, while the Tapercut and U-Groove ground electrode design supports efficient flame initiation in the combustion chamber.
Detailed Description
This Denso spark plug is a direct-fit style ignition component for applications that call for a 14 mm thread, 12.70 mm reach, flat seat, and 0.8 mm pre-gap. The iridium center tip and copper core construction are paired with a nickel ground electrode to balance durability and electrical performance. For buyers searching for Denso 5380 spark plug replacement, Denso Iridium Power 5380, or an OE-style iridium spark plug for ignition service, this part provides the core specifications needed for accurate matching. It is also cross-referenced to DENSO Auto Parts IWF24 for the same application.
What It Helps Address
- Misfires caused by worn or eroded spark plug electrodes
- Hard starting related to weak ignition spark
- Rough idle from inconsistent combustion
- Reduced throttle response from degraded plug performance
- Service replacement needs for vehicles using the specified plug dimensions
Installation Notes and Tips
Verify thread diameter, reach, seat type, heat range, and pre-gap before installation. Use the correct torque procedure for the engine and confirm the ignition system is in good condition before fitting the plug. For fitment-based searches such as Denso 5380 spark plug for Honda Civic or Denso Iridium Power 5380 for Toyota Corolla, match the engine’s required plug specifications rather than relying on vehicle name alone.
Quality Assurance
Denso manufactures this Iridium Power spark plug to defined dimensional and material specifications for ignition service. Confirm application details against the vehicle’s service information and the plug’s listed attributes before installation.
