K&N RU-4960XD XD Extreme Duty Round Tapered Air Filter 2.75in Flange 6in OD 5.5H

Vehicle Fitment

• Universal Fit - Designed for off-road vehicles, performance cold air intake systems, racing builds, and any application with a 2.75 in. intake tube demanding superior filtration in high-dust conditions

Fitment Notes

• This is a universal clamp-on filter - verify your intake tube outside diameter matches the flange inside diameter of 2.75 in. before purchasing
• Rubber flange can be stretched up to 1/16 in. (1.5 mm) to accommodate in-between sizes or angled intake configurations
• Note: despite the small 2.75-inch flange, this filter has a wide 6-inch base OD - verify engine bay clearance before purchasing
• Can be cleaned using the same K&N Recharger kit as standard K&N cotton gauze filters
• The standard oiled cotton version with identical dimensions is available as K&N RU-4960
• Not a direct OEM replacement for a specific vehicle - confirm fitment by measuring your intake tube diameter

Product Description

The K&N RU-4960XD is part of K&N's XD (Extreme Duty) Series - a line of clamp-on filters engineered specifically for off-road racing and high-dust environments. Sharing the same dimensions as the standard RU-4960 (2.75 in. flange, 6-inch base, 5.5-inch height), the XD variant uses a deep pile design and extra-fine weave grade cotton that delivers increased dust-holding capacity and filtration efficiency compared to the standard cotton gauze version. Developed from real-world testing at the Baja 1000 and validated against the ISO 5011 test protocol, the RU-4960XD is the right choice when maximum protection in harsh environments is the priority.

The centered 2.75 in. rubber flange mounts securely onto matching intake tubes, absorbs vibration, and can be stretched slightly to fit in-between sizes. Despite its extreme-duty construction, the RU-4960XD is cleaned using the same standard K&N Recharger service kit. Washable and reusable, it arrives pre-oiled and is ready to install out of the box. Made in the USA and backed by K&N's 10-Year/Million Mile Limited Warranty, the RU-4960XD is the go-to upgrade for any off-road or high-performance application requiring wide-diameter filtration through a 2.75-inch inlet in demanding conditions.
