Cold Air Intake for Acura TSX Sedan (2004-2007) 2.4L Engine without MAF Sensor Only Red

Maximize i-VTEC Airflow: 2004-2007 Acura TSX 2.4L K24A2 Performance Intake

Who Is This For? Designed specifically for 2004-2007 Acura TSX owners running the K24A2 i-VTEC engine who want to improve throttle response and hear that signature induction sound during daily driving and spirited weekend runs.

The Factory Airbox Restriction: You step on the gas to merge or engage VTEC, and the K24A2 feels like it’s gasping through a straw. The factory airbox is designed for silence, not speed, utilizing baffled chambers and restrictive paper filters that heat-soak quickly in traffic. This creates a noticeable lag in the low-to-mid range, preventing your TSX’s high-revving engine from reaching its true efficiency.

The Engineering Solution: We engineered this cold air intake system to provide a high-velocity, direct-flow path for oxygen-rich air. By utilizing polished aluminum piping and a high-flow washable filter, we eliminate the turbulence caused by the stock corrugated rubber hosing. This kit moves the air pickup point away from the hot engine block, ensuring a denser air charge enters the manifold for more consistent combustion and crisper acceleration.

The Comparative Edge: Why This Beats the Competition

• Enhanced High-RPM Breathability: Provides a significant increase in airflow volume during VTEC crossover, resulting in a more aggressive engine note and smoother power delivery.
• Aluminum Construction: Constructed from mandrel-bent aluminum, unlike cheaper plastic intakes that can crack or generic aluminized steel that will rust over time.
• True Bolt-On Fitment: Specifically designed for non-MAF (Mass Air Flow) sensor models, ensuring a perfect seal and zero check engine lights when installed correctly.
