| $2.50 | | | 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. |

| $12.75 | | Idle Control Valves  | | The idle control valve control valve adjusts and maintains the proper idle for the car whether it's cold or hot. Based on temperature sensors in the engine, the valve opens automatically to allow more airflow into the engine while cold, keeping the engine supplied with more air until it reaches a certain temperature. If the unit goes bad, it can cause rich running, idle fluctuation and hard starting. Also be sure to check out our article on Idle Speed Troubleshooting. |
