Review: High quality filter at an affordable price. - Great fit, high quality and good price. Bike runs like new again. Review: Excellent quality as expected of K&N - Fit was excellent, quality appeared to be top notch. Filter was smaller than I expected but bolted up to my Audi 1.8t with no problems at all, and no interference with the MAF or anything. Looking forward to cleaning, rather than replacing my filters. One minor downside is the screw type hose clam that comes with it is of the cheap stamped design. That doesn't bother me too much for my application, but it certainly would on a different car. ## 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01LCEEGQG | | Best Sellers Rank | #123,340 in Automotive ( See Top 100 in Automotive ) #1,871 in Automotive Replacement Air Filters | | Brand Name | K&N | | Customer Reviews | 4.5 4.5 out of 5 stars (526) | | Fit Type | Universal Fit | | Global Trade Identification Number | 00024844362865 | | Included Components | Air filter | | Item Dimensions L x W x H | 4.5"L x 2.75"W x 4.5"H | | Item Type Name | K&N RG-1003RD-L Universal Chrome Filter | | Item Weight | 0.4 Kilograms | | Manufacturer | K&N Engineering | | Manufacturer Part Number | RG-1003RD-L | | Manufacturer Warranty Description | 12 Months | | Model Number | RG-1003RD-L | | OEM Equivalent Part Number | RG-1003RD-L | | Product Grade | Replacement Part | | Shape | ['Oval', 'Round Tapered'] | | UPC | 024844362865 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** K&N - **Fit Type:** Universal Fit - **OEM Part Number:** RG-1003RD-L - **Product Dimensions:** 4.5"L x 2.75"W x 4.5"H - **Product Grade:** Replacement Part ## Images ![High-Flow Original Lifetime Universal Clamp-On Air Filter: Performance, Premium: Flange Diameter: 2.75 In, Filter Height: 4.5 In, Flange Length: 1 In, Shape: Round Tapered, RG-1003RD-L - Image 1](https://m.media-amazon.com/images/I/71W-Cz3sxhL.jpg) ![High-Flow Original Lifetime Universal Clamp-On Air Filter: Performance, Premium: Flange Diameter: 2.75 In, Filter Height: 4.5 In, Flange Length: 1 In, Shape: Round Tapered, RG-1003RD-L - Image 2](https://m.media-amazon.com/images/I/51nTgbQezZL.jpg) ![High-Flow Original Lifetime Universal Clamp-On Air Filter: Performance, Premium: Flange Diameter: 2.75 In, Filter Height: 4.5 In, Flange Length: 1 In, Shape: Round Tapered, RG-1003RD-L - Image 3](https://m.media-amazon.com/images/I/81CWRM1Dd8L.jpg) ![High-Flow Original Lifetime Universal Clamp-On Air Filter: Performance, Premium: Flange Diameter: 2.75 In, Filter Height: 4.5 In, Flange Length: 1 In, Shape: Round Tapered, RG-1003RD-L - Image 4](https://m.media-amazon.com/images/I/810EjNHr6lL.jpg) ![High-Flow Original Lifetime Universal Clamp-On Air Filter: Performance, Premium: Flange Diameter: 2.75 In, Filter Height: 4.5 In, Flange Length: 1 In, Shape: Round Tapered, RG-1003RD-L - Image 5](https://m.media-amazon.com/images/I/81GN3d2MHBL.jpg) ## Questions & Answers **Q: Will this fit my 2008 scion tc? if not what k&n high performance filter will?** A: Its 2020 dude, ask Google. **Q: What k&n filter will fit my 2000 saturn sc2 coupe ?** A: The RG-1003RD-L UNIVERSAL CLAMP-ON AIR FILTER MULTI LINGUAL is a universal filter.

Bike runs like new again. ### ⭐⭐⭐⭐⭐ Excellent quality as expected of K&N *by A***A on October 26, 2020* Fit was excellent, quality appeared to be top notch. Filter was smaller than I expected but bolted up to my Audi 1.8t with no problems at all, and no interference with the MAF or anything. Looking forward to cleaning, rather than replacing my filters. One minor downside is the screw type hose clam that comes with it is of the cheap stamped design. That doesn't bother me too much for my application, but it certainly would on a different car. ### ⭐⭐⭐⭐⭐ Worth every penny *by C***G on January 12, 2020* I drive a 2015 Mitsubishi Mirage and it’s a 3cyl Car. With that being said there is no aftermarket parts for it because of it A being a 3cyl and B there wasnt high demand for the car like is competitor the Honda Fit OR whatever it is. Granted I didn’t buy the case for its performance. But I heart couldn’t do with the stock intake on the car, it was large for no reason, an eye sore, and didn’t perform well. So I built a custom cold air intake from the throttle body to the filter. I used this cold air intake filter and man am I happy I switched to it. I initially bought just a generic cold air intake filter for $12 on amazon saying to myself, the rest you were just buying the brand name they all do the same thing. Granted they do, but to a certain extent. Since putting this filter on I’ve noticed a slight increase to my acceleration, response, and power. Now everyone take the word slight seriously. Any cold air intake will promise xyz for HP gains, but what they don’t tell you is your car who need to be tuned for any aftermarket part to gain the max promised HP. So if it says +5 HP it’s really probably 2 HP maybe 3 if you’re lucky. But still even with the little it gives I totally noticed it while driving. K&N of a very reputable brand name and today I learned why.
