Vance & Hines VO2 X Air Cleaner Kit For Harley Touring / Softail (2023–2026)
Aggressive Billet Styling Meets High-Flow Milwaukee-Eight Performance
Transform the intake performance and custom appearance of your late-model V-Twin with the Vance & Hines VO2 X Air Cleaner Kit. Engineered specifically for 2023.5 through 2026 Harley-Davidson Touring models (including Street Glide, Road Glide, and CVO editions) as well as 2025–2026 Softail platforms, the VO2 X replaces the restrictive factory air box with a high-capacity, open-element intake system built for maximum airflow velocity.
Featuring a CNC-machined billet aluminum outer cover over a washable, reusable filter element, the VO2 X incorporates Vance & Hines’ proprietary Force™ Velocity Stack backing plate. This streamlined design channels cold, unrestrictive air directly into the throttle body, smoothing out intake turbulence and generating noticeable gains in horsepower and torque across the entire powerband.

Airflow Dynamics & Engine Performance
### Force™ Velocity Stack Technology
Stock Harley-Davidson air cleaner assemblies utilize sharp internal turns and restrictive plastic baffles that restrict air delivery under load. The VO2 X features an oversized aluminum backing plate with an integrated Force™ Velocity Stack. This design creates a smooth venturi effect that pulls a higher volume of air quickly into the Milwaukee-Eight throttle body, delivering immediate throttle response and improved top-end pull.
### High-Capacity Washable Filter Element
The included pre-oiled filter element features deep pleats designed to capture fine dust particles while allowing maximum oxygen passage. Because it is completely washable and reusable, it offers long-lasting performance through thousands of miles of road service.

### Required Tools
- Hex key / Allen wrench set (3/16″, 5/32″)

### Step 1: Removal of Stock Air Cleaner
Ensure the engine is off and completely cool. Remove the outer air box cover screw and take off the factory plastic housing. Unbolt the stock paper filter element and backing assembly, carefully disconnecting the cylinder head breather lines. Gently wipe down the face of the throttle body using a clean cloth.
### Step 2: Installing Backing Plate & Breather Hardware
Apply blue thread locker to the new backing plate mounting screws. Secure the Vance & Hines aluminum backing plate and gasket to the face of the throttle body. Install the cylinder head breather bolts and torque all hardware evenly to factory service specifications.
### Step 3: Mounting the High-Flow Filter & VO2 X Cover
Seat the high-flow washable filter element onto the velocity stack ridge of the backing plate. Position the billet CNC VO2 X outer cover over the filter. Apply thread locker to the provided countersunk cover screws and tighten in a cross-pattern until firmly secured.
Frequently Asked Questions
### Is fuel tuning required after installing the VO2 X Air Cleaner?
Because the VO2 X increases airflow volume substantially over the OEM air box, adding an ECU tuner like the Vance & Hines Fuelpak FP4 is highly recommended to optimize air-fuel ratios and maximize overall power gains.
### How do I clean and service the filter element?
Inspect the filter every 5,000 miles. Clean using a standard V-Twin air filter wash kit, rinse gently from the inside out with low-pressure water, allow it to dry naturally, and re-oil before reinstalling.
