Generation II Fuel Injection Performance Kit

The K&N 57-2553 is a Generation II Fuel Injection Performance Kit (FIPK) engineered to significantly improve airflow to your engine. This cold air intake system replaces the stock air filter and intake tubing, minimizing air path restrictions to unlock your vehicle's natural horsepower potential. The system features a large, conical, red cotton gauze air filter designed for high-flow and exceptional filtration, requiring cleaning only every 100,000 miles under normal highway driving conditions. The intake tube is constructed from High-Density Cross-Linked Polyethylene (HDPE) using a roto-molded process. This allows for precise shaping to reduce turbulence and accelerate airflow, while also helping to lower air intake temperature and reduce intake sound compared to metal tubes. The kit includes necessary adapters made from high-strength materials like silicon and reinforced nylon to ensure durability and a secure connection. Mounting hardware is included, and typical installation can be completed in 60 minutes or less with basic hand tools. This K&N FIPK system is street legal and comes with K&N's No-Hassle Lifetime Limited Warranty. It is designed to provide a guaranteed increase in horsepower and torque, with an estimated gain of 13.07 HP at 4979 RPM. The system is specifically designed for 2003-2004 Ford Crown Victoria models with the 4.6L V8 engine.
