Chrome Air Intake for Acura TSX (2004-2008) 2.4L Engine

Improve High-RPM Breathing and VTEC Induction Sound on your Acura TSX K-Series

Who It’s For: Designed specifically for 2004–2008 Acura TSX (CL9) owners running the high-revving K-Series engine. Whether you’re daily driving or hitting the occasional track day, this is for the enthusiast who wants to hear their i-VTEC engage while improving overall engine efficiency.

The Problem: The K-Series (K24A2) is one of the best four-cylinders ever built, but the factory airbox is a massive bottleneck. To keep the car quiet for the average consumer, Acura used a series of restrictive baffles and a heavy resonator box hidden in the fender. This creates turbulent airflow and robs the K24A2 of the crisp throttle response it was engineered for.

The Solution: We replaced that restrictive plastic maze with a high-flow, polished T-304 aluminum intake system. This kit provides a more direct, mandrel-bent path for air to reach the throttle body. By reducing intake resistance, we allow the K-Series to breathe easier at high RPMs, correcting the factory’s conservative airflow bias and delivering a much more aggressive tone when the VTEC crossover kicks in.

Why This is the Ultimate Upgrade

• Enhanced Induction Flow: The smooth-bore aluminum piping reduces turbulence compared to the ribbed factory rubber hoses, allowing for faster air velocity.
• T-304 Aluminum Construction: Lightweight and durable, the polished finish helps reflect engine bay heat more effectively than darker plastics, while providing a show-quality look.
• Simple Bolt-On Installation: This is a true direct-fit kit that utilizes factory mounting points. No cutting, welding, or ECU re-flashing is required for immediate results.
