K&N High-Flow Universal Clamp-On Air Filter RE-0930, 3 in Flange 6 in Height — Washable & Reusable

The K&N High-Flow Original Universal Clamp-On Air Filter (RE-0930) is a washable, reusable performance cone filter with a 3-inch flange and 6-inch height engineered to boost airflow and last the life of your vehicle.

This clamp-on filter from K&N blends increased air intake capability with durable materials and a universal design that fits many aftermarket and replacement applications. Built with multiple layers of specially treated cotton gauze and a pliable rubber flange, it’s intended to deliver better airflow than stock paper elements while reducing ongoing maintenance costs because it can be cleaned and reused.

How does this filter improve engine breathing and performance?

The RE-0930 uses four layers of premium cotton gauze with a tackified treatment to create a dense, yet highly permeable media that allows more air to pass through while trapping contaminants. Increased airflow can help throttle response and may support modest gains in horsepower when paired with compatible intake systems.

• Multi-layer cotton gauze media engineered for high flow
• Special tacking agent to capture dust and particles
• Designed to complement aftermarket intake setups and clamp-on installations

What makes the clamp-on design and materials durable?

K&N constructs the RE-0930 with a molded pliable rubber flange that resists vibration and allows a tight, secure attachment to round intake tubes. The frame and media are built to withstand typical engine bay conditions and, unlike disposable filters, the design supports repeated cleaning cycles without losing shape.

• Molded rubber flange absorbs vibration and seals to the intake tube
• Sturdy frame and media resist oil and heat from engine environments
• Pre-oiled from the factory to maintain performance out of the box

How often does the filter need service and how is it maintained?

Under normal highway driving, the filter typically requires cleaning about every 75,000 miles (roughly every five years based on average annual mileage). When cleaning is needed, follow K&N’s cleaning kit instructions: remove, apply cleaner, rinse, dry, and re-oil to restore the media’s filtration and flow characteristics.

• Recommended cleaning interval: ~75,000 miles in normal highway use
• Service process: clean, dry, and re-oil using K&N cleaning kit
• Reusable design reduces disposable filter waste and replacement costs

What are the key dimensions and fitment details?

The RE-0930 is a round tapered (cone-style) clamp-on filter with a 3-inch flange diameter, 6-inch overall height, and 1.75-inch flange length. These dimensions suit many clamp-on intake applications — always verify flange size and available clearance before purchasing to ensure proper fit.

• Flange diameter: 3 inches — matches 3" intake tubes
• Filter height: 6 inches, tapered cone profile for compact installations
• Flange length: 1.75 inches to accommodate secure clamping

Who this is for: The K&N RE-0930 clamp-on air filter is ideal for DIY mechanics, performance enthusiasts, and anyone seeking a long-lasting replacement or aftermarket intake filter that improves airflow without recurring disposable filter purchases. It’s especially suitable for custom or universal intake setups where a 3-inch flange and a compact cone filter are the right fit.
