One way to tweak your Prius to maximize performance, efficiency, and fuel economy, is by adding a Prius Cold Air Intake. Contrary to common belief, the goal isn't to deliver as much air as possible into the engine, but to optimize it. INJEN designed their Prius Intakes to do just that by modifying the shape, size, and reworking of parts to create a quality intake you just won't find elsewhere.
The K&N air filter is designed to achieve high, virtually unrestricted air flow while maintaining filtration levels critical to ensure long engine life. Our automotive OE (original equipment) replacement air filters generally add 1-4 horsepower. 1.8L
