K&N Engineering 57 FIPK Air Intake for Increased Airflow with HDPE Tube

K&N Engineering 57 FIPK Air Intake — Increased Airflow with HDPE Tube Upgrade your engine's breathing with the K&N 57 FIPK (Fresh Intake Performance Kit). Engineered with a rotationally-molded high-density polyethylene (HDPE) tube , this intake increases intake volume and smooths airflow to deliver real gains in horsepower and torque. High-Flow Performance: Tuned HDPE tubing and optimized runner design maximize airflow for improved throttle response and power across the RPM band. Washable, Reusable Filter: Oversized conical High-Flow air filter with premium oiled cotton media—clean and re-oil instead of replace. Under normal highway driving, service intervals can extend up to 100,000 miles . Heat Protection: Custom heat shield reduces intake air temperatures by isolating the filter from engine bay heat, preserving density and performance. Simple Installation: Designed for straightforward bolt-on installation—most applications install in under 90 minutes with common tools. Durable Construction: Rotationally-molded HDPE resists heat soak and delivers consistent flow characteristics over time. Note: Some K&N intakes are not legal for sale or use on pollution-controlled motor vehicles in California. Refer to product specifications for CARB status for your specific vehicle.
