: At just 0.4mm, the Iridium center electrode reduces the voltage required to spark, which improves ignitability even under lean conditions.
: 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 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 : At just 0
: The ground electrode features a unique U-shaped groove that allows the flame kernel to expand more quickly. This leads to more complete combustion and reduced carbon fouling. Thread Diameter: 10mm
: 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.
The 5285 is popular among enthusiasts for its ability to improve the combustion process.
