A vehicle intake system is similar to the human respiratory system. Air is taken in, filtered and then distributed to the essential engine components so the car can run properly. Without proper air distribution, a car fails to function properly. Despite major advances in vehicle intake systems, there's still a need to clean them periodically to prevent the harmful buildup of carbon, soot or other deposits that can hinder your vehicle's performance. This product effectively removes these deposits. Using the 3M Intake System Cleaner could also help save money since some auto mechanics charge $80 or more for an intake system cleaning. The 3M instake system cleaner is sold individually, or as part of a more robust package of intake system cleaners. As an individual item, the cleaner is suitable for professional or at home use. Normal safety procedures are recommended when using this product. Keep out of reach of children, use gloves when handling and consider using a half face-piece of full face-piece air-purifying respirator that's suitable for organic vapors.
