Denso | 5285

Tapered-cut nickel with a U-Groove design.

: 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. denso 5285

While widely used across various platforms, the 5285 is most commonly found in: IRIDIUM POWER - Specifications | Products | SPARK PLUG Tapered-cut nickel with a U-Groove design

: 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

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.

: At just 0.4mm, the Iridium center electrode reduces the voltage required to spark, which improves ignitability even under lean conditions.
