K&N RU-2800 Universal Clamp-On Round Tapered Air Filter 5in Flange 6.5in OD 7in

Vehicle Fitment

• Universal Fit - Designed for performance vehicles, cold air intake systems, racing builds, and any application with a 5.00 in. intake tube requiring a large clamp-on tapered air filter
• Also used as a replacement filter for STM 5-inch performance intake systems including Jeep Trackhawk builds

Fitment Notes

• This is a universal clamp-on filter - verify your intake tube outside diameter matches the flange inside diameter of 5.00 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
• Not a direct OEM replacement for a specific vehicle - confirm fitment by measuring your intake tube diameter

Product Description

The K&N RU-2800 is a high-flow universal clamp-on round tapered air filter built for large-displacement performance cold air intakes, racing builds, and high-CFM applications requiring a 5-inch flange. Its tapered cone profile - 6.50 inches at the base narrowing to 4.375 inches at the top over a 7-inch height - delivers an expansive cotton gauze surface area to support the most demanding intake flows while maintaining excellent contaminant filtration. The multi-layer oiled construction flows significantly more air than any paper element, translating to sharper throttle response and substantial horsepower gains on high-output builds.

The centered 5.00 in. rubber flange mounts securely onto matching intake tubes, absorbs vibration, and can be stretched slightly to fit in-between sizes. A stainless steel hose clamp is included for a secure, leak-free installation. Washable and reusable, the RU-2800 arrives pre-oiled and is ready to install out of the box. It is backed by K&N's 10-Year/Million Mile Limited Warranty and made in the USA - making it a reliable, long-term upgrade for any large-displacement performance or racing application requiring a wide-format round tapered clamp-on filter.
