Air intake for Acura Integra (2022-2025) 1.5L Engine

High-Flow Performance Air Intake for 2022-2025 Acura Integra (L15CA/DE4)

What it Does: Replaces the restrictive factory air box and corrugated plastic inlet with a mandrel-bent aluminum induction system to decrease intake air temperatures and improve turbocharger spool-up time.

The Stock Integra Airflow Deficiency

The OEM Acura Integra intake tract is designed primarily for NVH (Noise, Vibration, and Harshness) suppression rather than volumetric efficiency. The factory system utilizes corrugated plastic tubing which creates significant internal air turbulence, disrupting the laminar flow essential for optimal compressor wheel efficiency. Furthermore, the stock plastic air box is highly susceptible to heat soak; during spirited driving or stop-and-go traffic, the plastic components retain engine bay heat, warming the incoming air charge and reducing oxygen density. This thermal retention leads to inconsistent timing pull and a noticeable loss in low-end torque during heat-heavy conditions.

The Engineering Solution

This kit resolves OEM bottlenecks by utilizing mandrel-bent aluminum alloy piping. Unlike molded plastic, mandrel bending maintains a constant internal diameter throughout every curve, ensuring a smooth, high-velocity path for the air charge. Aluminum provides superior heat dissipation properties, cooling down rapidly once the vehicle is in motion. The system features a high-flow dry media filter, which offers increased surface area for filtration without the risk of MAF (Mass Air Flow) sensor contamination often caused by oiled filters. The kit is secured with high-grade silicone couplers and stainless steel T-bolt clamps, engineered to withstand high vacuum and boost pressures without deformation or leaks.

The Acura Performance Standard

As a staple of the JDM-tuner segment, the Integra demands components that enhance its precision-engineered L-series engine. This intake provides the necessary airflow overhead for those seeking improved throttle response and a more pronounced turbo induction sound without sacrificing filtration integrity.
