Performance Cold Air Intake System for 2004–2007 Acura TSX – 2.4L Airflow & Output

Elevate the performance and efficiency of your sedan with this high-performance cold air intake system, specifically engineered for the 2.4L i-VTEC engine. Designed to replace the restrictive factory air box and tubing, this upgrade creates a high-velocity air path that allows your engine to breathe more freely. By drawing in a larger volume of cooler, oxygen-rich air, you unlock more immediate throttle response and a noticeable increase in power throughout the entire RPM range.

By drawing in cooler, denser air from outside the engine bay, this system optimizes the combustion process for increased efficiency. The improved oxygen density helps your vehicle achieve smoother acceleration and increased torque, providing a more confident and engaging feel whether you are navigating city streets or merging onto the highway. Along with the performance gains, you’ll enjoy a deeper, sportier engine note that perfectly complements the high-revving character of the TSX.

Key Features & Performance Benefits

• Optimized Induction: Replaces restrictive factory components with a lightweight T-304 polished aluminum intake pipe designed to minimize air turbulence.
