Air Cleaner Intake Filter Kit for Harley Street Glide Dyna Softail Fatboy Low Rider (1993-2015) - Black

High-Flow Turbine Air Intake Kit for 1993-2015 Harley Davidson Road King, Street Glide (Twin Cam / Evolution)

Replaces the restrictive factory air box with an exposed turbine-style filter to maximize volumetric efficiency and improve throttle response across the RPM range.

The Stock Road King & Street Glide Intake Bottleneck

The OEM air cleaner assembly on 1993-2015 Harley-Davidson models is engineered primarily for noise suppression and emissions compliance, often at the cost of engine breathing. The factory plastic backing plate and enclosed housing create significant air turbulence and restriction, especially as the engine transitions into the mid-to-high RPM range. Furthermore, the stock paper filters are susceptible to heat soak from the cylinder heads, which increases intake air temperatures (IATs) and reduces oxygen density. This lack of airflow prevents the Evolution and Twin Cam engines from reaching their full volumetric potential, resulting in sluggish throttle response and a muffled exhaust note.

The Engineering Solution

This Turbine Air Cleaner kit is a precision-engineered upgrade that utilizes a high-volume, exposed filter design to eliminate intake vacuum restrictions. The assembly features a CNC-machined billet aluminum face plate for structural rigidity and heat dissipation. It incorporates a specialized backing plate that promotes laminar airflow directly into the carburetor or throttle body, minimizing the drag coefficients found in the stock unit. The system includes built-in internal crankcase breathers, which eliminate the need for external hoses and simplify the intake tract. The reusable, pre-oiled cotton gauze element provides superior filtration while allowing a significantly higher CFM (Cubic Feet per Minute) rating than standard paper elements, ensuring the engine draws cooler, denser air for increased combustion efficiency.

The Harley Davidson Standard

Designed for the long-haul rider and performance enthusiast, this intake kit provides the durability required for heavy V-Twin vibration. The billet aluminum construction ensures the assembly will not warp or crack under high thermal loads, providing a reliable seal at the intake manifold and preventing unfiltered air from entering the combustion chamber.
