Air Cleaner Intake Filter Kit for Harley Road Glide (2008-2016)

High-Flow Turbine Air Intake System for 2008-2016 Harley Davidson Road Glide (Twin Cam / FL Frame)

What it Does: Replaces the restrictive factory air box with an open-element turbine system to maximize CFM delivery and improve volumetric efficiency across the powerband.

The Stock Road Glide Intake Deficit

The OEM intake assembly on 2008-2016 Touring models is engineered primarily for noise attenuation and EPA compliance rather than peak performance. The enclosed plastic housing creates significant aerodynamic drag and intake turbulence, which starves the throttle body during high-load scenarios. This restriction results in increased pumping losses and contributes to heat soak, as the plastic backing plate fails to dissipate heat efficiently. Over time, factory plastic components are prone to warping, which can compromise the seal at the induction module and allow unfiltered air to enter the combustion chamber.

The Engineering Solution

This kit utilizes a precision-machined aluminum backing plate and a 3-hole gasket configuration to provide a rigid, airtight interface with the throttle body. The turbine-style exposed filter design eliminates the restrictive outer shell, allowing for 360-degree atmospheric access and a more direct, laminar flow path into the venturi. Unlike the stock setup, this system features integrated internal crankcase breathers, eliminating the need for external hoses and providing a cleaner aesthetic while managing blow-by. The high-performance pleated media offers a larger surface area than the stock paper element, ensuring superior particulate filtration without sacrificing the airflow required for modified or high-output Twin Cam engines.
