Denso 5285: Updated

: Iridium is six times harder and eight times stronger than platinum, allowing it to withstand the extreme temperatures of high-performance engines without degrading. Applications and Compatibility

While widely used across various platforms, the 5285 is most commonly found in: IRIDIUM POWER - Specifications | Products | SPARK PLUG denso 5285

24 (Denso scale), which is considered a "cold" plug suitable for high-speed or high-load conditions. Thread Diameter: 10mm. Reach: 19mm (3/4"). Hex Size: 16mm (5/8"). Key Features and Benefits : Iridium is six times harder and eight

The Denso 5285 is defined by its precision engineering and high-grade materials. Below are the key technical specifications provided by Denso Auto Parts : 0.4mm Iridium-tipped fine wire. Reach: 19mm (3/4")

The 5285 is popular among enthusiasts for its ability to improve the combustion process.

: By minimizing "quenching" (the loss of heat to the electrodes), the Denso 5285 allows for faster flame growth, resulting in measurable improvements in throttle response and acceleration.
