57i Series Performance Air Intake System

The K&N 57i Series induction kit is engineered to enhance engine performance by improving airflow and throttle response. This system replaces the complete factory air intake, overcoming the restrictive design of stock components. Its open-air filter design allows for increased airflow, which K&N guarantees will increase horsepower and provide a more responsive driving experience across the entire RPM range. The K&N cotton gauze air filter features a larger surface area, capturing more dirt and extending service intervals up to 100,000 miles before cleaning is required. Installation is straightforward, typically taking 90 minutes or less. This K&N 57 Series Generation II intake system is designed for specific vehicle models. The available fitment information indicates compatibility with Ford Fiesta IV (1.3L F/I, 1998-2002), Ford Ka II (1.25i, 11/1999-2002), and various European vehicle applications. Please consult the full application list to confirm fitment for your specific vehicle.
