K&N Engineering 57 FIPK Air Intake HDPE Tube with High-Flow Filter

K&N Engineering 57 FIPK Air Intake HDPE Tube with High-Flow Filter Upgrade engine performance with the K&N 57 FIPK (Free-Flow Intake Performance Kit). This precision-designed intake combines a rotationally-molded HDPE tube and a washable, reusable High-Flow conical filter to deliver increased airflow, improved throttle response, and measurable gains in horsepower and torque. Key Features Enclosed air box design shields the filter and inlet air from engine bay heat for cooler, denser intake air. Tool-free access — the air box lid provides quick, easy filter access for fast service. HDPE rotationally-molded tube increases airflow volume while maintaining strength and heat resistance. Washable, reusable High-Flow filter with oiled cotton media for long life and superior filtration. Oversized conical filter allows up to 100,000 miles between services under normal highway driving conditions. Simple installation — most systems install in under 90 minutes with common tools. Why Choose K&N 57 FIPK This kit is engineered for reliable, long-term performance: increased airflow, reduced intake temps, and repeatable gains without sacrificing filtration. Ideal for enthusiasts seeking durable, street-ready performance improvements with easy maintenance.
