Review: Amazing filter I love K&N - Works great and fits on my cold long ram tube perfectly. If I need to I will buy again, easy to clean and well worth the money. Other filters don’t even sound as good as this one Unsure if it added horse power but added sound definitely Review: Fabbed up a custom CAI. - Custom CAI couldn't have turned out better, I was going for the "sleeper" style of intake but didn't like the idea of cutting a hole in the hood for a ram cowl induction. This filter as some of you know, it being a K&N filter needs to be oiled and washed to keep contaminants out. The filter pricetag was pretty cheap considering the quality you are getting. The filter looks well made, no factory defects I can see of. If the filter is ducted like I did, you get the added bonus of the intake rush noise, and colder incoming air. No more 'hot air intake' with the filter being setup this way also, just be sure to not choke the engine of air, or you're going to be running the engine with a rich A/F, Size ducting accordingly. The only part of this project that sucked was that I needed to cut a hole into the radiator core support, for the ducting/filter to come through. ## 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00AFRIVNQ | | Best Sellers Rank | #9,230 in Automotive ( See Top 100 in Automotive ) #1 in Automotive Performance Air Filters | | Brand | K&N | | Brand Name | K&N | | Customer Reviews | 4.6 out of 5 stars 5,086 Reviews | | Fit Type | Universal Fit | | Global Trade Identification Number | 00024844313317 | | Included Components | 6" OD B X 5.5"H W/4", 3-1/2", 3"DIA FLG W/INVERTED FILTER TOP | | Item Dimensions L x W x H | 3.5"L x 4"W x 3"H | | Item Type Name | 6" OD B X 5.5"H W/4", 3-1/2", 3"DIA FLG W/INVERTED FILTER TOP | | Item Weight | 1.7 Pounds | | Manufacturer | K&N Engineering | | Manufacturer Part Number | RG-1001RD | | Manufacturer Warranty Description | LIMITED WARRANTY | | Model Number | RG-1001RD | | OEM Equivalent Part Number | RG-1001RD | | OEM Part Number | RG-1001RD | | Product Dimensions | 3.5"L x 4"W x 3"H | | Product Grade | Replacement Part | | Shape | Round | | UPC | 024844313317 | | Unit Count | 1 Count | ## Product Details - **Brand:** K&N - **Fit Type:** Universal Fit - **OEM Part Number:** RG-1001RD - **Product Dimensions:** 3.5"L x 4"W x 3"H - **Product Grade:** Replacement Part ## Images ![High-Flow Original Lifetime Universal Clamp-On Air Filter: High Performance, Premium: Flange Diameter: 4 In, Filter Height: 5.5 In, Flange Length: 1.125 In, Shape: Round Tapered, RG-1001RD - Image 1](https://m.media-amazon.com/images/I/81fmmwwrPCL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: will this fit 2008 gmc sierra Denali?** A: Depends on how big your intake tube is **Q: Whats the difference with the RR-3003 ?** A: If your intake tube is 3" or 3.5" or 4" in diameter **Q: Im assuming this is not a hydrophobic (water-resistant/proof,) is it?** A: It is not. Any open cone filter isn't. If you're going to do an external mod such as out the hood or aft of the front grill, make a shield for it.
