Air intake for Acura Integra (2023-2025) 1.5L Engine

High-Flow Performance Air Intake for 2023-2025 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.

Compatibility

• 2023-2025 Acura Integra 1.5T CVT or 6 Speed MT

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.

Common Questions

Will this intake fit my Acura Integra 1.5L with either the CVT or 6-speed manual?
Yes, this system fits the Acura Integra DE4 with the 1.5L turbocharged L15CA engine equipped with either the CVT automatic or the 6-speed manual transmission.

Will this fit the Acura Integra Type S?
This intake is built specifically for the DE4 chassis with the 1.5L L15CA engine, whereas the Integra Type S uses the DE5 chassis and a larger engine.

What components are included in the kit?
The kit includes mandrel-bent aluminum alloy intake piping, a high-flow dry media air filter, high-grade silicone couplers, and stainless steel T-bolt clamps.

Is the included air filter oiled or dry media?
It comes with a high-flow dry media filter designed to maximize filtration surface area while avoiding MAF sensor contamination from filter oil.

How does this upgrade improve on the factory intake?
It replaces the restrictive plastic air box and corrugated inlet tube with smooth mandrel-bent aluminum piping to reduce air turbulence, dissipate engine bay heat, and improve throttle response and turbo spool-up.
