Product Description

The K&N RF-1047 is a premium universal clamp-on high-flow air filter engineered for performance use across a broad range of vehicles and aftermarket intake systems. With its washable and reusable cotton gauze media, this filter helps boost airflow while maintaining strong filtration to protect the engine.

Its design features a 3-inch flange for clamp mounting, a 6-inch base diameter, and a height of 6 inches - making it suitable for many custom setups, replacement intakes and high-flow demands. The carbon-fiber composite top enhances durability while keeping the weight down.

Because this is a universal-fit component rather than a vehicle-specific part, you should verify fitment by measuring your intake flange diameter and available clearance in your engine bay. Though compatible with many builds, specific year/make/model/engine applications are not listed, so fitment through 2025 is unconfirmed.
