Denso IU27 Iridium Spark Plug

Maximize your engine's performance with the Denso IU27 Iridium Spark Plug. Designed for optimal combustion and longevity, this spark plug delivers superior ignition and fuel efficiency. Upgrade your motorcycle's spark plugs for a smoother ride and increased power.

Description

The Denso IU27 Iridium Spark Plug is engineered for exceptional performance and durability. Featuring an iridium electrode that is six times harder than platinum and capable of withstanding temperatures up to 4,000°F, this spark plug ensures reliable ignition under extreme conditions. The 0.4mm iridium electrode reduces voltage requirements while enhancing firing performance. The 360° laser-welded electrode provides a robust seal that resists wear, ensuring a long service life. Furthermore, the ground electrode's tapered cut and U-groove design create a large volume area for the flame's center, promoting efficient combustion and increased power. This spark plug is a resistor type with a 10 mm thread size and a 19.1 mm (3/4") thread reach, making it compatible with a wide range of motorcycles.
