Review: Just what you'd expect from K&N. - I've ordered many of this exact part over the years. This is a real K&N part so it perfectly matches the old one it replaced. If you like other K&N oiled filters, you'll like this one too. It comes with a replacement hose clamp in case you need another one. I always reuse the old one and just put the new on on the shelf. The clamps don't really go bad but I suppose I have spares if I ever need one. Review: Great filter - Great filter. Fit perfect. ## Features - ENGINEERED POWER: State-of-the-art air filter media is designed to increase horsepower and acceleration as well as improve overall engine performance - 4 LAYERS OF PROTECTION: Multiple layers of premium cotton gauze treated with a specially-designed tacking agent work together to create an intricate mesh of engine filter media that is designed to block and trap harmful contaminants - RUGGED CONSTRUCTION: K&N Universal Air Filters are manufactured with durable, premium materials and state-of-the-art construction methods to last a lifetime - CLEAN ONCE EVERY 5 YEARS: Engine air filter only needs cleaning every 75,000 miles under normal highway driving conditions (5 years based on the average miles driven per year of 15,000 miles) - EASY INSTALLATION: K&N Air Filters are pre-oiled and ready to drop into your factory air box- they are one of the easiest and most cost-effective vehicle upgrades for quick performance gains - UNIVERSAL FITMENT: Designed for use on a variety of applications - REDUCES WASTE: Over 200 million disposable air filters and their packaging waste wind up in landfills each year- reusable filters help reduce waste in our landfills - NO-HASSLE WARRANTY: 1-Year Limited Warranty - MADE IN USA: K&N Air Filters are proudly made in the USA for trusted quality & reliability ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00062ZNXG | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #124,621 in Automotive ( See Top 100 in Automotive ) #1,659 in Automotive Replacement Air Filters | | Brand | K&N | | Customer Reviews | 4.7 4.7 out of 5 stars (516) | | Date First Available | November 21, 2004 | | Exterior | Machined | | Global Trade Identification Number | 00024844076007 | | Is Discontinued By Manufacturer | No | | Item Weight | 1.7 pounds | | Item model number | RF-1041 | | Manufacturer | K&N Engineering | | Manufacturer Part Number | RF-1041 | | Model | Universal Clamp-On Air Filter | | OEM Part Number | RF-1041 | | Product Dimensions | 3"L x 7.5"W x 7.5"H | | Shape | cylindrical | | UPC | 024844076007 | ## Product Details - **Brand:** K&N - **Fit Type:** Universal Fit - **OEM Part Number:** RF-1041 - **Product Dimensions:** 3"L x 7.5"W x 7.5"H - **Product Grade:** Replacement Part ## Images ![High-Flow Original Lifetime Universal Clamp-On Air Filter: High Performance, Premium, Washable: Flange Diameter: 6 In, Filter Height: 7.5 In, Flange Length: 1 In, Shape: Round Tapered, RF-1041 - Image 1](https://m.media-amazon.com/images/I/61rfXI7nX2L.jpg) ## Questions & Answers **Q: What are the dimensions on this filter?** A: As per K&N part # RF-1041 measures as :Air Filter Large End Diameter 7.5 in (191 mm) Base Outside Diameter 7.5 in (191 mm) Flange Inside Diameter 6 in (152 mm) Flange Length 1 in (25 mm) Flange Type Centered Height 7.5 in (191 mm) Top Outside Diameter 5 in (127 mm) **Q: Is this California smog-legal?** A: No **Q: Is this filter compatible with mopar intake tube for jeep wrangler (jk, jku) 2012-2017?** A: Yes **Q: Is this air filter 6 inches** A: Yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Just what you'd expect from K&N. *by C***M on July 31, 2025* I've ordered many of this exact part over the years.
