K&N High Flow Air Filter for Harley Davidson Screamin Eagle - HD-0800

K&N High-Flow Air Filter | Harley-Davidson Screamin' Eagle (HD-0800)

The HD-0800 is a specialized high-performance filter designed as a direct replacement for Harley-Davidson models equipped with the Screamin' Eagle Stage 1 Air Cleaner Kit. Unlike "drop-in" filters meant for the stock plastic airbox, the HD-0800 is a round-tapered element that bolts onto the high-flow metal backing plate used in the classic Screamin' Eagle upgrades for Twin Cam engines.

Key Features

• Optimized for Stage 1 Kits: Engineered specifically to fit the Screamin' Eagle air cleaner assembly. It provides the high-velocity, low-restriction airflow required to maximize the performance of a re-mapped EFI system.

  +1

   

• Premium Engine Protection: Features K&N’s signature multi-layered oiled cotton gauze media. It maintains a 99% filtration efficiency, protecting your 88ci, 96ci, or 103ci engine from fine dust while allowing it to breathe more deeply.

   

• Washable & Reusable: A permanent "Lifetime" performance upgrade. You can wash, re-oil, and reinstall the filter indefinitely. Under normal highway conditions, it typically only requires cleaning every 80,000 km (50,000 miles).

  +2

   

• High-Quality Construction: Built with a durable zinc-coated top plate and an application-specific sealing bead to ensure a 100% airtight seal against the backing plate.

   

• Aggressive Intake Sound: Because this filter is part of an open-element system, it provides a much more noticeable and visceral intake "roar" compared to stock or enclosed filters.

Why Choose K&N for your Screamin' Eagle?

If your bike already has the Screamin' Eagle upgrade, the HD-0800 is the best way to maintain that performance. Factory-supplied filters in those kits are often synthetic or paper-blend disposables; upgrading to the K&N element ensures sharper throttle response and a more consistent air-fuel ratio. It is a direct replacement for Harley-Davidson OEM part number 29442-99A.
