Performance Cold Air Intake System for 2004–2007 Acura TSX 2.4L – Improved Intake Efficiency & Measurable Performance Increases

Ensure your TSX's maximized airflow and engine performance boost with this precision-engineered cold air intake system. Engineered specifically for 2.4L engine models produced without a MAF sensor, this kit replaces the restrictive factory air box that often limits the potential of your sedan during spirited driving or highway merging. By utilizing a high-flow induction setup to optimize the way your engine breathes, this system provides the cooler, denser air charge needed for improved combustion efficiency and a more capable driving experience.

The factory intake components are designed for silence over speed, often creating bottlenecks that restrict the engine's ability to breathe under load. Cooler air carries more oxygen, which translates into a more intense explosion in the combustion chamber to create more horsepower and torque. This system utilizes a high-flow induction tube that effectively reduces air turbulence, allowing your 2.4L engine to act as a more efficient air pump and providing a performance increase of up to 10% throughout the entire RPM range.

Key Features & Performance Benefits

• Power Gain: Increases horsepower and torque by up to 10% for sharper acceleration and improved top-end pull.

• Thermal Management: Designed to draw in cooler air from outside the engine bay to maintain a denser air charge.

• Instant Response: Streamlines the air intake to provide a more direct connection between the pedal and the pavement.

• Engine Tone: Enhances the signature induction sound of the 2.4L engine under heavy acceleration, providing a more aggressive note.

• Consistent Flow: Maintains steady air velocity for reliable performance across all driving conditions.

• High Filtration: Blocks harmful debris while allowing maximum airflow for the demands of the high-revving i-VTEC power plant.

Vehicle Fitment

Acura TSX

2004–2007 Sedan models with 2.4L Engine

Note: Fits models without a Mass Air Flow. NO (MAF) sensor engines only.

What's Included

Your kit features the high-velocity induction piping, a reusable high-flow performance air filter, and all required couplers, clamps, and hardware for a complete and secure installation.

Installation Tip

Disconnect the NEGATIVE GROUND CABLE from the battery before starting the installation and keep it off for at least one minute after you finish. This reset allows the engine's computer to learn the new airflow parameters and adjust accordingly. Ensure the engine is completely cool before beginning work.
