|  | | | BMW E46 Intake System - Page 1 | Air Filters  | | An essential part of any tune up is replacing the air filter. Over time, sir filters collect dirt and dust, eventually clogging up. The result is poor performance, poor fuel economy and rough running. Often times, replacing a clogged filter can make a car run like new. |

| $3.00 | | | K&N Air Filters | | K&N air filters are designed to achieve high, virtually unrestricted air flow while maintaining filtration levels critical to ensure long engine life. The secret to their success lies in the unique characteristics of their filter medium that was originally developed by K&N all those years ago in the dust, sweat and tears of desert motocross racing. The high flow cotton gauze air filter is washable, reusable and built to last for the life of an engine. The filters consist of four to six sheets of cotton gauze layered between two sheets of aluminum wire mesh. This media is then pleated and oiled to enhance its filtering capabilities and overall performance. The result is an air filter that allows dramatically more air into an engine, is washable and reusable, and will protect your engine for the life of your vehicle. |
