Product Description

The K&N E-3770 is a premium high-flow round air filter designed for applications where the factory or aftermarket airbox accepts an element sized approximately 14" outside diameter, 12" inside diameter and 6" height. Its washable and reusable cotton gauze media improves airflow and engine breathing while maintaining strong filtration and engine protection.

Installation is straightforward when your airbox layout matches the size profile: remove your existing filter element, insert the E-3770, and secure the airbox. Since it comes pre-oiled, you can install and drive without extra prep.

Because this is a universal-style filter, it is not assigned to a specific make, model, year or engine. Buyers must verify the physical dimensions of their airbox and available clearance before purchase. Compatibility with all vehicles through 2025 is unconfirmed - ensure the element fits properly in your setup.
