The DENSO IWF24 Iridium Spark Plug, manufacturer part number 5380 and vendor part number 5380, is engineered for reliable ignition and consistent performance in demanding engine applications. Its iridium construction provides exceptional durability and heat resistance, withstanding temperatures up to 4,000°F. The fine iridium center electrode helps reduce the voltage required for ignition while supporting improved firing performance and dependable starts.
DENSO uses 360° laser welding on the electrode to create a secure seal that resists wear, even under severe operating conditions. The ground electrode features a tapered cut and U-groove design that creates a larger flame-center area, promoting efficient combustion and stable engine operation. These design features make the IWF24 suitable for replacement applications requiring a high-performance iridium spark plug.
Verify vehicle, engine, and application fitment before installation. The DENSO IWF24 spark plug is identified by model IWF24, brand DENSO, manufacturer part number 5380, and vendor part number 5380.
