Description
Overview
The AWE Tuning Secondary Air Injection Pump Filter is a purpose-built breather filter designed for certain Audi and Volkswagen vehicles equipped with a Secondary Air Injection (SAI) system. When you upgrade your intake, some applications rely on a small dedicated filter to keep the SAI hose properly served — and that’s exactly the role this accessory fills. It’s a small part with an important job, ensuring your intake setup is complete and correct.
If your vehicle has a Secondary Air Injection hose, this filter is a required accessory to finish the installation the right way. Not sure whether your car needs it? Reference the handy fitment image to locate the SAI on your engine and confirm whether it applies to your setup before you order.
Key Benefits
Built from cotton filter media, this AWE Tuning breather filter is engineered as part of the air intake ecosystem, giving the Secondary Air Injection pump the dedicated filtration point it needs.

AWE Tuning backs this piece with a Fit Guarantee and a No CEL Guarantee, so you can install with confidence knowing it’s designed to integrate cleanly with the compatible Audi and Volkswagen SAI systems. All necessary hardware is included, making for a straightforward, complete installation with everything you need in the box.

Pairing the correct breather filter with your intake ensures the Secondary Air Injection pump has proper filtration and that your overall setup functions as intended.
