Volant 15037 High Performance Cold Air Intake System - Compatible with [Vehicle Model] - Improves Engine Power & Fuel Efficiency - Perfect for Off-Roading & Racing Enthusiasts

This is a must have for the Chevy Colorado and GMC Canyon 3.5 and 3.7 liter inline 5 for sure. Taking apart the factory setup it is essentially a bottleneck. The Volant opens up air flow niceley. It was well thought out when it was designed and looks great under the hood. Throttle response is instantly better. Before there was a lag from hitting the gas and getting results from the engine. It now requires less throttle to cruise up the street or maintain speed. At cruising and idle speed it sounds the same as factory, but when you stomp on the gas a bit instead of sounding like an outboard boat motor is has a growl like an engine that can really perform. I've used other CAI's on different cars I owned and this is best upgrade even if you plan on no other upgrades.
