K&N High Flow Air Filter for Harley Davidson XR 1200 - HD-1208

K&N High-Flow Air Filter | Harley-Davidson XR1200 (HD-1208)

The HD-1208 is the dedicated performance intake upgrade for Harley-Davidson’s sport-focused XR1200 and XR1200X. Unlike standard Sportsters, the XR series features a unique downdraft fuel injection system and a specialized airbox; the HD-1208 is precision-engineered to fit this specific geometry, ensuring the high-output Evolution V-Twin gets the unrestricted airflow it needs.

Key Features

• High-Output Breathing: Designed to provide up to 50% more airflow than the factory paper element. This is essential for the XR1200, which features larger throttle bodies and performance-tuned heads compared to the standard XL Sportster.

• Race-Proven Filtration: Features K&N’s signature multi-layered oiled cotton gauze media. It provides excellent engine protection by trapping 99% of contaminants while maintaining the high air velocity required for rapid throttle response.

   

• Washable & Reusable: A permanent "Lifetime" 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).

• Direct Drop-In Fit: Precision-molded to provide a 100% airtight seal within the XR1200's unique airbox. It is a direct replacement for Harley-Davidson OEM part number 29377-08.

• Included Sealing Grease: Often packaged with a 1oz tube of K&N sealing grease to ensure a leak-proof fit against the airbox base, preventing "dirty" air from bypassing the filter.

Why Upgrade Your XR1200?

The XR1200 was built to pay homage to the XR750 flat-track racers, meaning it thrives on revs and aggressive riding. The stock air filter is designed with noise compliance in mind, which can create a bottleneck at high RPMs. The HD-1208 "uncorks" the intake tract, providing a crisper throttle snap and allowing the engine to pull harder all the way to redline. It is a mandatory first step for any owner looking to maximize the "Sport" in Sportster.
