Review SUBARU Air Intake Tube Aem Inlet Pipe Assembly Oem fits WRX 2015–2021

Introducing the AEM Inlet Tube (Part Number: 21-836C) designed specifically for the Subaru WRX models from 2015 to 2021. This high-performance air intake tube is an excellent upgrade for those seeking to enhance their engine's breathing capabilities.

The AEM Inlet Tube is meticulously engineered to provide improved airflow and filtration over the stock intake system. Manufactured from 6061-T6 aluminum, this tube boasts a polished finish that not only looks great but also ensures a perfect fitment and durability.

The tube utilizes a large, open-element air filter housing, which allows for increased airflow and a more efficient intake system. The included AEM Dryflow Synthetic Air Filter offers exceptional filtration efficiency, ensuring that only clean air enters the engine.

By relocating the air filter away from the heat sources under the hood, such as the exhaust manifold and catalytic converter, the AEM Inlet Tube helps maintain optimal air temperature, ultimately resulting in improved engine performance and horsepower gains.

This AEM Inlet Tube kit comes complete with all necessary hardware for a straightforward installation process. It is designed to work seamlessly with the OEM mass air flow sensor and throttle body, ensuring a smooth and hassle-free integration into your Subaru WRX.

Upgrade your Subaru WRX with the AEM 21-836C Air Intake Tube and experience the difference in engine performance, improved throttle response, and enhanced driving experience.
