- How can I confirm whether this bypass valve filter fits my vehicle?
- Please check your intake pipe diameter and installation space before ordering. This product is designed for 76mm / 3 inch compatible intake pipe applications.

- It helps support intake airflow and filtration in compatible cold air intake systems, while helping reduce dust, debris and road particles entering the intake pipe.

- It is designed for 76mm intake pipe applications. Please measure your intake pipe before ordering.
- Is this product easy to install?
- Yes. The clamp-on structure supports simple installation on matching intake pipes, but professional installation is recommended if buyers are not familiar with intake system modification.
