K&N High Flow Air Filter for Harley Davidson Street 750 - HD-4915

K&N High-Flow Air Filter | Harley-Davidson Street 750 (HD-4915)

The HD-4915 is the essential performance intake upgrade for Harley-Davidson’s liquid-cooled Revolution X platform. Designed to fit the Street 750 (XG750) and the Street 500 (XG500), this filter replaces the factory disposable element and backing plate, allowing the high-revving V-twin to draw air more efficiently for improved mid-range pull.

Key Features

• Revolution X Optimization: Specifically designed to support the 749cc (and 494cc) liquid-cooled engines. It provides up to 50% more airflow than standard paper filters, which is crucial for maintaining power in urban stop-and-go traffic.

• Premium Engine Protection: Features K&N’s signature multi-layered oiled cotton gauze media. It provides exceptional filtration efficiency (rated at approximately 98.97%) while keeping the intake velocity high.

• Washable & Reusable: A permanent "Lifetime" performance upgrade. You can wash, re-oil, and reinstall the filter, typically requiring service only every 80,000 km (50,000 miles) depending on dust conditions.

• Direct Drop-In Fit: Precision-engineered to replace the factory disposable air filter and its backing plate. It fits perfectly behind the stock air cleaner lid—just remember to reuse your factory rubber gasket for a 100% seal.

• Enhanced Performance Profile: Reduces the "choked" feeling of the stock intake, providing a crisper throttle response and a more authoritative intake thump that complements the Revolution X exhaust note.

Why Choose K&N for your Street 750?

The Harley-Davidson Street 750 was built for the urban grid, where heat and dust can quickly degrade a standard paper filter. The HD-4915 not only allows the engine to breathe easier but is also far more durable in harsh environments. It is a favorite modification for riders who have added a "slip-on" exhaust, as it helps balance the engine's air-fuel ratio for a smoother, more responsive ride.
