Product Details

Highlights

  • Six times harder than platinum, iridium withstands temperatures up to 4,000F.
  • Because the iridium electrodes of these plugs can be shrunk to only 0.4mm, voltage requirements decrease while firing performance improves.
  • 360 laser welding of electrode provides a seal that resists wear even in the worst conditions.
  • Ground electrode features a tapered cut and U-groove that form a large volume area for the flame's center.

Elevate the performance of your ride with the Arlen Ness Monster Sucker Air Cleaner Kit—a must-have for any serious rider seeking peak efficiency. This innovative kit boasts the renowned Big Sucker "hidden breather" technology, seamlessly integrating breathers that are O-ringed at the heads and venting directly through to the injector or carburetor. This design eliminates the need for cumbersome external hoses or hardware, ensuring a sleek and efficient setup. The Monster Sucker's filter is engineered for superior air intake, featuring an inverted top that draws in more air from every angle, including the front. This results in a significant boost in airflow and engine performance. Constructed from a high-quality synthetic material, the filter is water-resistant, making it reliable in various weather conditions and reducing the need for additional rain protection. Plus, its reusable design means no more dealing with messy oils—just rinse and reuse. Please note that the Arlen Ness cover is sold separately, and this kit is not compatible with models featuring fairing lowers. Transform your motorcycle’s breathing capabilities with the Arlen Ness Monster Sucker Air Cleaner Kit and experience unmatched performance on the road.
