K&N High-Flow Air Filter | Harley-Davidson Touring & Softail 103ci (HD-1614)
The HD-1614 is a high-performance intake upgrade specifically engineered for Harley-Davidson’s "High Output" (HO) Twin Cam 103ci engines. This filter is the standard replacement for the 2014–2016 Touring models and the 2016–2017 Softail models that utilize the factory "Rushmore" style air cleaner.
Key Features
-
Optimized for Rushmore Intake: Designed to fit the high-velocity airboxes introduced in the Project Rushmore era. It provides up to 50% more airflow than the stock paper element, supporting the increased torque of the 103 HO engine.
-
Superior Filtration: Features K&N’s signature multi-layered oiled cotton gauze media. It provides world-class engine protection by trapping 99% of contaminants while maintaining the high air speed required for the fuel injection system.
-
Washable & Reusable: A "Lifetime" performance modification. You can clean, re-oil, and reinstall this filter indefinitely. It typically only requires servicing every 80,000 km (50,000 miles) depending on your riding environment.
-
Direct Drop-In Fit: Precision-molded for a perfect, airtight seal within the factory airbox. It is a direct "plug-and-play" replacement for Harley-Davidson OEM part number 29400045.
-
Intake Harmony: Enhances the visceral intake "growl" of the Twin Cam engine, providing a more authoritative sound during heavy roll-on acceleration.

Why Choose K&N for your 103 HO Harley?
The 2014+ Touring and 2016+ Softail models were designed for better performance, but the stock intake is still a major bottleneck due to noise and emission restrictions. The HD-1614 "uncorks" the intake tract, resulting in a sharper throttle response and more consistent power delivery, especially when riding two-up or fully loaded. It is the ideal foundation for a "Stage 1" upgrade.
