Product Description

The K&N E-3491 is a premium high-flow oval air filter crafted for applications requiring an element roughly 8.875" long, 5.25" wide and 6" tall. With washable and reusable cotton gauze media, this filter offers both performance and long-term value by improving engine breathing while maintaining solid engine protection.

Installation is straightforward where the air box accepts this approximate size: simply remove the existing filter, insert the E-3491, and secure the air box lid. Since it comes pre-oiled, you're ready to go after installation.

Because this unit is a universal-shape filter and not vehicle-specific, buyers must check their air box dimensions and clearance before purchase. Fitment through 2025 for specific vehicles is unconfirmed.
