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 element for multiple K&N performance intake kits - verify your specific intake kit part number before ordering

Fitment Notes

Product Description

The K&N RU-5147 is a high-flow universal clamp-on round tapered air filter built for large performance cold air intakes, racing builds, and high-CFM applications requiring a 5-inch flange in a compact 5.5-inch height. Its tapered cone profile - 6.50 inches at the base narrowing to 4.50 inches at the top - delivers substantial cotton gauze surface area to support demanding 5-inch 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 measurable horsepower gains.

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. Washable and reusable, the RU-5147 arrives pre-oiled and only needs cleaning every 75,000 miles under normal conditions. It is backed by K&N's 10-Year/Million Mile Limited Warranty and made in the USA - a reliable, long-term upgrade for any large-format performance or racing application requiring a compact tapered filter with a 5-inch inlet.
