Cold Air Intake Kit for Acura TSX (2004-2008) with 2.4L 4-Cylinder Engine Black

Optimize K24A2 Induction with this High-Flow Intake for 2004-2008 Acura TSX

Who It’s For: Designed specifically for first-generation Acura TSX owners looking to improve the breathing capabilities of the high-revving K24A2 engine.

The Problem: The factory airbox is designed for silence, not speed. By using restrictive baffles and corrugated plastic tubing, the stock system chokes the 2.4L K-Series at high RPMs, leading to heat soak and a sluggish throttle response that masks the true potential of the VTEC system.

The Solution: This intake replaces the restrictive factory assembly with smooth-bore T304 aluminum piping. We engineered this system to deliver a high-velocity air charge directly to the manifold, ensuring the engine draws in cooler, denser oxygen for more efficient combustion and crisper acceleration.

Why This is the Ultimate Upgrade

• Instant Throttle Response: Eliminates the air turbulence found in stock corrugated hoses, providing immediate engine reaction the moment you tip into the pedal.
• Durable T304 Construction: The lightweight aluminum piping is built to withstand engine bay heat without warping or cracking, outlasting factory plastic components.
• Maintenance-Free Filtration: Features a high-flow, washable synthetic filter that only requires cleaning every 50,000 miles, eliminating the need for expensive paper filter replacements.
