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

The K&N High-Flow Original Universal Clamp-On Air Filter (RE-0930) is a washable, reusable cone-style filter built to boost airflow and deliver long-lasting filtration for many clamp-on applications.

This tapered K&N clamp-on unit features a 3-inch flange diameter, 1.75-inch flange length and a 6-inch overall height, designed to be versatile across a wide range of aftermarket and replacement intake setups. Constructed with layered cotton gauze media and a flexible molded rubber flange, it balances increased air delivery with durable sealing and vibration resistance. Pre-oiled and ready out of the box, the filter is intended as a lifetime service part you clean instead of replace, reducing ongoing costs and waste.

How does this filter affect engine airflow and performance?

The K&N High-Flow media is engineered to allow greater volume of air into the intake compared with many disposable filters, helping engines breathe more freely under load and acceleration. Increased airflow can support improved throttle response and smoother power delivery without complicated tuning when used within typical bolt-on upgrades.

• Multi-layer cotton gauze media for high air permeability
• Pre-oiled construction for immediate use and trapping particulates
• Tapered cone shape to optimize flow into common intake pipes
• Designed to fit many clamp-on intake fittings for easy retrofit

What are the maintenance requirements and lifespan?

This clamp-on filter is washable and intended to be serviced rather than discarded. Under normal highway driving, you typically clean the element infrequently compared to disposable filters, and with proper care it can be reused for the service life of the vehicle.

• Pre-oiled filter — ready to install right away
• Service interval: long periods between cleanings under normal highway use
• Cleaning kits available from K&N to restore filtration efficiency
• Lifetime use when inspected and maintained per instructions

Will this clamp-on filter fit my intake plumbing or velocity stack?

The RE-0930 is a universal-style clamp-on with a 3-inch flange diameter and a 1.75-inch flange length designed to accommodate many aftermarket pipes and adapters. Because it’s a tapered round shape, it suits a range of applications, but verifying flange size and clearance in your engine bay ensures a correct fit.

• Flange diameter: 3 inches (measure your inlet tube to confirm)
• Filter height: 6 inches — check for hood or housing clearance
• Molded rubber flange for vibration dampening and secure clamping
• May require a clamp or adapter depending on your setup

How durable and environmentally responsible is this filter?

K&N designs these filters with rugged materials and construction methods intended for extended service life. Reusability reduces the number of disposable filters sent to landfills, and the robust rubber and media construction stands up to repeated cleanings and everyday vibration.

• Durable molded rubber flange for long-term sealing and vibration absorption
• Multi-layer media built to withstand multiple cleanings
• Replaces disposable filters to lower ongoing waste and cost
• Backed by a limited warranty and made in the USA for quality assurance

Who is this for: The K&N RE-0930 clamp-on air filter is made for vehicle owners, hobbyists and mechanics who want a versatile, reusable cone filter for aftermarket intakes, velocity stacks or custom applications. It’s well suited to those seeking to improve intake airflow and reduce recurring filter purchases, provided you confirm flange size and physical clearance before ordering.
