Review: Fits , works , sounds good ie the air intake and a fool could fit it... - Brilliant but of kit 👌 got it for a 2012 1.6L ford focus and believe it or not you can definitely feel the difference and the throaty intake sound sounds great. I really didn't think I feel a difference but yes breathing much better... Review: Growling Ecoboost! - Fitted this with ease to the Ford Ecoboost 1.6 180 BHP engine, now I have the low down torque and induction sound I wanted. Turbo also makes a satisfying whoosh on change of gears. Fuel consumption has slightly improved also. Well worth the money. ## Features - Replacement air filter for 57S-4000 - Comes with a K&N embossed lid cap - Designed to boost horsepower and rate of acceleration ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00CR9WY38 | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | 108,283 in Automotive ( See Top 100 in Automotive ) 824 in Car Air Engine Air Filters | | Brand | K&N | | Brand Name | K&N | | Country Of Origin | USA | | Customer Reviews | 4.7 out of 5 stars 352 Reviews | | EU Spare Part Availability Duration | 10 Years | | Fit Type | Vehicle Specific Fit | | Fit type | Vehicle Specific Fit | | Global Trade Identification Number | 00024844178732 | | Included Components | 70MM FLG, 146MM B, 151MMT OD, 195MM H | | Item Dimensions L x W x H | 18.4L x 18.4W x 22.9H centimetres | | Item Shape | Round | | Item Type Name | K&N Replacement Air Filter Conical 70mm flange, 146mm base, 151mm top, 195mm height (E-9289) | | Item Weight | 0.5 Kilograms | | Manufacturer | K&N | | Manufacturer Part Number | E-9289 | | Manufacturer Warranty Description | 1,000,000 Miles | | Model Number | E-9289 | | Number of Items | 1 | | Number of Packs | 1 | | OEM Equivalent Part Number | E-9289 | | OEM part number | E-9289 | | Product Grade | Performance Part | | Product dimensions | 18.4L x 18.4W x 22.9H centimetres | | Product grade | Performance Part | | UPC | 024844178732 | | Unit Count | 1.0 count | ## Product Details - **Brand:** K&N - **Product dimensions:** 18.4L x 18.4W x 22.9H centimetres - **EU Spare Part Availability Duration:** 10 Years - **OEM part number:** E-9289 - **Global Trade Identification Number:** 00024844178732 ## Images ![K&N Engine Air Filter: High Performance, Premium, Washable, Industrial Replacement Filter, Heavy Duty: E-9289 - Image 1](https://m.media-amazon.com/images/I/513gtf2keXL.jpg) ![K&N Engine Air Filter: High Performance, Premium, Washable, Industrial Replacement Filter, Heavy Duty: E-9289 - Image 2](https://m.media-amazon.com/images/I/81q1SZsepPL.jpg) ![K&N Engine Air Filter: High Performance, Premium, Washable, Industrial Replacement Filter, Heavy Duty: E-9289 - Image 3](https://m.media-amazon.com/images/I/71bk8tKfqxL.jpg) ![K&N Engine Air Filter: High Performance, Premium, Washable, Industrial Replacement Filter, Heavy Duty: E-9289 - Image 4](https://m.media-amazon.com/images/I/819xH7IPrvL.jpg) ![K&N Engine Air Filter: High Performance, Premium, Washable, Industrial Replacement Filter, Heavy Duty: E-9289 - Image 5](https://m.media-amazon.com/images/I/81KlGzT88JL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Does this fit mk2 focus rs** A: I can't give a definite answer as I got it for a 1.6 focus eco boost mk3.
