Description

The K&N 77-2578KS high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Ford Flex models. The restrictive factory air filter and air intake housing on your vehicle are replaced by this K&N air intake system which is designed to dramatically reduce air flow restriction as it smoothes and straightens air flow. The improved air flow allows your engine to inhale a larger amount of air than it would from the stock air intake. More air means more usable power and acceleration throughout your engine's RPM range.
