K&N Universal Clamp-On Air Filter

K&N Universal Clamp-On Air Filter | High-Flow Washable Performance

Upgrade your engine's airflow with a K&N Universal Clamp-On Air Filter. Featuring washable 4-layer cotton gauze media for increased horsepower & longevity.

Engineered to unlock maximum airflow and peak engine performance, the K&N Universal Clamp-On Air Filter is built for enthusiasts and custom builders who demand uncompromised reliability. Constructed with multi-layered, oiled cotton gauze media held between aluminum wire mesh, this high-flow filter allows up to 50% more air to enter your engine compared to standard paper filters.

Unlike throwaway paper filters that need frequent replacement, K&N’s universal filters are completely washable and reusable. Built with ultra-durable, vibration-absorbing molded pliable rubber flanges, these clamp-on filters secure tightly onto intake tubing without slipping or leaking under harsh driving conditions. Pre-oiled directly from the factory, it delivers immediate bolt-on performance while providing up to 99% filtration efficiency to safeguard your engine against harmful dirt and debris.

Best Uses

1. Custom Engine Air Intakes: Ideal for custom car builds, hot rods, muscle cars, and turbocharged or supercharged setups requiring custom intake piping.
2. Motorcycles & ATVs: Direct clamp-on solution for motorcycles, quad bikes, dirt bikes, and snowmobiles equipped with aftermarket air intakes or velocity stacks.
3. Motorsport & Track Vehicles: Perfect for race cars, track-day vehicles, and karting where maximum airflow and throttle response are critical.
4. Off-Road & Utility Vehicles: High-dust applications like off-road buggies, side-by-sides (UTVs), and generators needing heavy-duty engine protection.

Features

1. High-Flow Oiled Cotton Media: Made with 4 to 6 layers of premium woven cotton gauze treated with a specialized tacking agent to trap dirt particles while optimizing airflow.
2. Pliable Molded Rubber Flange: Ultra-strong flexible rubber flange absorbs engine vibrations and stretches up to ensure a snug clamp-on fit.
3. Pleated Design for Maximum Surface Area: Deep pleats maximize the effective filtration area, extending service intervals and maintaining high airflow even as dust accumulates.
4. Heavy-Duty Clamp Included: Comes equipped with a durable, zinc-plated worm-gear hose clamp for fast, secure bolt-on installation.
5. Washable & Reusable Construction: Engine-tested materials designed to be washed, re-oiled, and reinstalled over and over without losing structural integrity.

Benefits

1. Increased Horsepower & Throttle Response: Low intake restriction allows air to flow into the combustion chamber faster and more efficiently, delivering noticeable power gains.
2. Long-Term Cost Savings: Eliminates the need to repeatedly buy disposable paper filters—buy it once and reuse it for the lifetime of your vehicle.
3. Superior Engine Protection: Traps up to 99% of harmful microscopic contaminants (dust, dirt, and debris) before they reach internal engine components.
4. Eco-Friendly Choice: Reduces landfill waste by replacing hundreds of single-use disposable air filters throughout your vehicle's lifecycle.
5. Hassle-Free Maintenance: Requires minimal upkeep—only needs servicing every 50,000–75,000 miles under standard road conditions.
