When you want to get great engine function from your vehicle, the most important thing is to properly support the engine itself with the right systems and components. A great engine, for example, relies on a steady stream of air in order to function properly: because the internal combustion processes of an engine require the presence of oxygen, getting the right air flow to the engine is crucial. With a great Chevy Avalanche Cold Air Intake, you’ll have the benefits of great air flow throughout your engine system - guaranteed. There are a few major features to look for in a great cold air intake system. One is definitely mechanical and design aspects that point towards greater air flow: you want wide pipe diameters (to allow a large volume of air through), mandrel-bent tubing (to avoid sharp, constrictive turns), and smooth pipe interiors to reduce air resistance. Another major feature of a great Chevy K&N Cold Air Intake is temperature maintenance: cool air has a higher density of oxygen than does warm air, which is why it is important to keep your intake tubing insulated from the high heat of the engine components themselves. When you’ve got the right cold air intake in your 2005 - 2006 Chevy Avalanche, you’ll be ensuring great engine function that is efficient and smooth - day in and day out.
