Product Description

The K&N E-3515 is a large-format high-flow oval air filter element built for custom, hot rod, and performance builds that use K&N's 66 Series large oval air cleaner assemblies or any compatible housing matching these dimensions. At nearly 15 inches long and over 7 inches wide, this element offers exceptional filter surface area to support high-CFM intake demands while still trapping contaminants before they enter the engine. The multi-layer oiled cotton gauze construction flows significantly more air than any paper element of comparable size.

Washable and reusable, the E-3515 arrives pre-oiled and only requires service every 50,000 miles under normal use. It is emissions legal in all 50 U.S. states, works seamlessly with OEM vehicle electronics, and is backed by K&N's 10-Year/Million Mile Limited Warranty. Whether you're refreshing a classic muscle car air cleaner or building a custom engine setup that demands a large oval element, the E-3515 is a long-lasting, performance-proven solution.
