Product Description

The Perrin X-PEP-INT-203 is a 4.5in foam replacement air filter designed as the direct-fit filter for Perrin Performance's Mitsubishi EVO 8 and EVO 9 intake systems. Built from open cell reticulated polyurethane foam, it captures dust and dirt effectively while keeping airflow restriction to a minimum, supporting the performance gains the intake system is designed to deliver.

Unlike disposable paper filters, this foam filter is washable and reusable, and can last the life of the vehicle with regular maintenance. Its two-piece design lets you remove the foam element for cleaning - simply rinse it out, let it dry, and apply a fresh coat of filter oil before reinstalling. Installation is straightforward and typically takes less than 15 minutes.

Beyond its role as the EVO 8/9 replacement filter, the X-PEP-INT-203 is also compatible with any aftermarket intake system that accepts a 4.5in filter neck, making it a useful option for other builds using that same filter size. It's backed by Perrin's 5-year manufacturer warranty.
