Air Cleaner Intake Filter Kit for Harley Touring Road King Glide (2008-2016) - Chrome CNC

High-Flow CNC Air Intake for 2008-2016 Harley Davidson Road King, Road Glide (Twin Cam / FLH)

What it Does: This CNC-machined air cleaner replaces the restrictive factory air box, utilizing an exposed filter design and high-velocity backing plate to optimize laminar airflow directly into the throttle body.

The Stock Road King, Road Glide Air Intake Bottleneck

The factory air cleaner assembly on 2008-2016 Touring models is engineered primarily for noise reduction and emissions compliance, which creates a significant pneumatic bottleneck at higher RPMs. The enclosed plastic housing often traps ambient heat, leading to increased intake air temperatures (IATs) and reduced oxygen density. Additionally, the stock breather system vents oil vapor into the combustion chamber in a non-optimized manner, often leading to carbon buildup on valves and piston crowns. This restriction prevents the Twin Cam 96 and 103 engines from reaching their true volumetric efficiency, particularly when paired with high-flow exhaust systems.

The Engineering Solution

This kit employs a precision CNC-machined aluminum backing plate designed with a radiused inlet to eliminate turbulence and promote smooth, high-velocity airflow. By utilizing an exposed 360-degree filter element, the surface area for induction is vastly increased compared to the OEM paper element. The integrated internal crankcase breathers utilize a discrete internal routing system, eliminating the need for external hoses and maintaining a clean aesthetic while ensuring crankcase pressure is managed without mess. The high-volume pleated filter media provides superior filtration efficiency without the static pressure drop associated with stock assemblies, resulting in sharper throttle response and improved torque delivery across the powerband.

The Harley Davidson Touring Standard

For long-haul Road Kings and Road Glides, airflow is critical for maintaining thermal stability and consistent torque during heavy-load cruising or mountain passes. This intake ensures your Twin Cam maintains peak performance without the parasitic loss of a choked-off factory intake.

Common Questions

Will this air cleaner kit fit my 2008-2016 Harley Road King or Road Glide?
Yes, this kit is a direct bolt-on fit for 2008-2016 Harley-Davidson Touring models—including the Road King and Road Glide (FLH and FLT chassis)—equipped with Twin Cam engines and electronic Throttle-By-Wire.

Does this intake work on bikes with a traditional cable throttle?
This kit is engineered specifically for Harley-Davidson models equipped with electronic Throttle-By-Wire (TBW), which comes standard on 2008-2016 Touring bikes.

How does the crankcase breather system work on this backing plate?
The CNC-machined aluminum backing plate features integrated internal crankcase breathers with discrete internal routing, eliminating the need for external breather hoses.

Will this fit a 2017 or newer Milwaukee-Eight Touring model?
This air cleaner assembly is built specifically for 2008-2016 Touring models running the Twin Cam 96, 103, and 110 engines.

What makes this kit flow better than the factory Harley air box?
It replaces the enclosed plastic factory housing with an exposed 360-degree high-volume pleated filter and a radiused CNC aluminum inlet to reduce intake heat soak and airflow restriction.
