Your vehicle’s engineers went to a great deal of trouble to make sure your engine could get a steady supply of the proper fuel and air mixture. Air intake control valves are necessary for this process. These parts take information from your engine computer, which in turn gathers data from various sensors located around your fuel, transmission and exhaust systems. This information about the current state of performance lets your computer tell your air intake control valves how much oxygenated air to allow into the system. Basically, these valves contribute to your vehicle’s performance and fuel efficiency. Get faulty parts replaced to lower your fuel bills, control noxious emissions and reclaim lost engine power.
