HKS RS NCP31/NCP13 RS 1NZ-FE

The HKS Racing Suction Air Filter is designed to provide maximum airflow. The Hyper Stealth Frame enhances air intake efficiency by 27%, allowing the engine to breathe easier and delivering a significant boost in power. It features high-performance 2-layer polyurethane foam infused with high-viscosity adhesive for superior filtration and exceptional airflow. Optimized suction pipes provide a balance of high-flow efficiency and low-resistance airflow for peak engine performance. The flexible frame support allows for easy maintenance and filter replacement, securing to an aluminum back plate. The signature "Super Lip Funnel" maximizes air intake surface area, and 16 parabolic frames provide lightweight construction for smooth airflow. Direct throttle mounting eliminates air intake restrictions, improving engine response and overall performance.
