K&N High Flow Air Filter for Harley Davidson Street Rod - HD-7517

K&N High-Flow Air Filter | Harley-Davidson Street Rod 750 (HD-7517)

The HD-7517 is the specialized performance intake upgrade for the Harley-Davidson Street Rod (XG750A). It is important to note that while the Street Rod belongs to the "Street" family, its High-Output Revolution X engine uses a completely different airbox than the standard Street 750 (which uses the HD-4915). The HD-7517 is designed to fit the unique, high-volume air intake system that defines the Street Rod's aggressive performance.

Key Features

• High-Output Breathing: Engineered specifically for the Street Rod's dual-throttle-body-fed engine. It provides up to 50% more airflow than the stock paper element, supporting the increased redline and higher compression of the XG750A.

• Superior Filtration Efficiency: Features K&N’s signature multi-layered oiled cotton gauze media. This allows for massive air volume while maintaining excellent filtration levels (approximately 99%) to protect the engine's internals.

   

• Washable & Reusable: A "Lifetime" performance modification. Instead of buying expensive OEM disposables, you simply wash, re-oil, and reinstall the HD-7517. It typically only needs cleaning every 80,000 km (50,000 miles) under standard street conditions.

• Direct Drop-In Fit: Precision-molded to provide a 100% airtight seal within the Street Rod’s factory airbox. It is a direct "plug-and-play" replacement for Harley-Davidson OEM part number 29400269.

   

• Unlocks the Intake Note: Reduces the intake restriction, allowing the High-Output Revolution X engine to produce a more visceral and aggressive intake "howl" during hard acceleration.

Why Choose K&N for your Street Rod?

The Street Rod 750 was designed to be the "sportier" sibling in the Street lineup, featuring more power and more lean angle. However, the stock intake can be a bottleneck when you're pushing the bike toward its higher 9,000 RPM redline. The HD-7517 ensures that the engine isn't "gasping" for air at high speeds, resulting in a sharper throttle response and a more linear power delivery. It is an essential first upgrade for anyone looking to maximize the "Rod" in Street Rod.
