Cobb Tuning Aluminum VB Intake Tube - 2022+ Subaru WRX

The COBB Aluminum Intake Tube for your 2022+ Subaru WRX is designed to maximize airflow potential while retaining the factory airbox and its integrated hydrocarbon trap, a federally mandated emissions component. This upgraded tube replaces the factory corrugated piece between the airbox and turbocharger inlet, improving flow and long-term reliability without requiring any changes to the stock airbox.

Constructed from 3" mandrel bent aluminum and finished in a wrinkle black powder coat, this intake tube provides a smooth, turbulence-reducing path for incoming air. Black 5-ply silicone couplers and included clamps ensure a secure, leak-free connection that stands up to engine bay heat and repeated heat cycling.

Product Highlight - 2022+ Subaru WRX Intake Upgrade

Key Features

• 3" Mandrel Bent Tubing: Smooth, unrestricted airflow from the factory airbox to the turbocharger inlet.
• Wrinkle Black Powder Coat: Durable finish that resists corrosion and blends cleanly into the WRX engine bay.
• Retains Factory Airbox: Keeps the OEM hydrocarbon trap in place for emissions compliance.
• 5-Ply Silicone Couplers: Black multi-layer silicone couplers with included clamps for a leak-free installation.
• Improved Airflow Over Stock: Removes corrugated and restrictive factory sections that can induce turbulence.
• Tune-Friendly: Compatible with the stock tune and COBB Off-The-Shelf (OTS) maps.

Why We Like It

This intake tube upgrade delivers real benefits without compromising emissions components or requiring a full intake swap. You get better airflow, cleaner under-hood aesthetics, and more durable materials than the factory plastic tube, which is prone to fatigue and cracking over time.
