Although it obviously doesn't give any noticeable increase in acceleration, it does seem to get me about 5% increase on MPG. What's more noticeable in all the cars is the low end power, the smoothness of the drives and how much less I need to change down a gear when slowing through village roads (I live in a rural area). It's just a *nicer* drive even on the 1.7 diesel with 190k miles (305k km!) on it. Plus not cleaning vs replacing seems slightly better for the environment. Review: Million mile warranty. Never needs changed for the price ... - Million mile warranty. Never needs changed for the price of 2 or 3 standard ones. Get the re-oiling solution as well, had difficulty finding it locally near Glasgow, Scotland. ## Features - Year: 3/12- - Info - K & N Replacement Filter ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003LS15XY | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | 227,028 in Automotive ( See Top 100 in Automotive ) 1,706 in Car Air Engine Air Filters | | Brand | K&N | | Brand Name | K&N | | Country Of Origin | USA | | Customer Reviews | 4.6 out of 5 stars 806 Reviews | | EU Spare Part Availability Duration | 10 Years | | Fit Type | Universal Fit | | Fit type | Universal Fit | | Global Trade Identification Number | 00024844282620 | | Included Components | HYUNDAI TUCSON L4-2.0/2.4L F/I; 2010-2015 | | Item Dimensions L x W x H | 25.7L x 16.5W x 2.2H centimetres | | Item Shape | Round | | Item Type Name | K&N 33-2451 Replacement Air Filter | | Item Weight | 0.8 Pounds | | Manufacturer | KN Filters Inc. | | Manufacturer Part Number | 33-2451 | | Model Number | 33-2451 | | Number of Items | 1 | | Number of Packs | 1 | | OEM Equivalent Part Number | 281131R100, 281132S000, 281132S100, 281133S000, 281133X000, 281133Z100, K281133X000 | | OEM part number | 281131R100, 281132S000, 281132S100, 281133S000, 281133X000, 281133Z100, K281133X000 | | Product Grade | Performance Part | | Product dimensions | 25.7L x 16.5W x 2.2H centimetres | | Product grade | Performance Part | | UPC | 024844282620 | | Unit Count | 1.0 count | ## Product Details - **Brand:** K&N - **EU Spare Part Availability Duration:** 10 Years - **Fit type:** Universal Fit - **Product dimensions:** 25.7L x 16.5W x 2.2H centimetres - **Product grade:** Performance Part ## Images ![K&N Engine Air Filter: High Performance, Washable, Replacement Filter: Compatible 2010-2019 Hyundai/Kia (i40, Elanta GT, i30, Elantra, ix35, Tucson, Carens, cee d, Forte, Forte 5, Certao, K3) 33-2451 - Image 1](https://m.media-amazon.com/images/I/818Xb0PBRIL.jpg) ## Questions & Answers **Q: Will this one fit a 2015 kia proceed 1.6 diesel?** A: If you enter "Car accessories for a Kia Proceed" in the Amazon Search bar, it will bring up a filter questionnaire to enter the exact details for your vehicle.
