Universal Clamp-On Air F ilter

The Universal Clamp-On Air Filter from K AND N ENGINEERING (RU-0830) is an essential upgrade for any mechanic or automotive enthusiast looking to improve engine breathing and performance across a wide range of vehicles. Unlike restrictive OEM air boxes, this clamp-on design allows you to relocate the filter element closer to the intake source, reducing intake temperatures and increasing airflow efficiency. Whether you're building a custom intake manifold, tuning a high-performance engine, or simply seeking better filtration flexibility on a non-standard setup, this universal filter delivers the adaptability professional rebuilds demand.

K AND N's signature design combines a durable clamp-mount base with their proven reusable cotton-blend media, engineered to balance flow capacity against filtration efficiency. The 4.63-inch inlet diameter and 7.25-inch overall height accommodate most common intake hose diameters, while the lightweight construction (0.77 lbs) eliminates parasitic weight that could affect throttle response. The clamp-on mounting system allows for precise positioning without modification to engine bay architecture—critical when working with custom carburetors, fuel injection conversions, or turbo/supercharger installations where factory filter locations become impractical.

Professional mechanics and hot-rod builders rely on this universal filter for classic car restorations, engine swaps, and performance modifications where off-the-shelf solutions don't exist. Installation requires only a hose clamp sized to match your intake diameter—no complex fabrication or fitment guesswork. This filter pairs seamlessly with forced-induction builds, carbureted engines, and EFI systems alike, making it an invaluable component for any serious engine compartment project where intake design flexibility takes priority.
