HKS 17-20 HONDA CIVIC SI US CIVIC SI

The most powerful intake system, specifically built to fit a vehicle’s engine area. HKS Racing Suction pushes the efficiency of air intake systems to the utmost. “Hyper Stealth Frame” outperforms the previous Super Stealth frame. Increasing the surface area of the air intake by 27% enhances air intake efficiency. The funnel’s outside border is securely fastened to the aluminum back plate. The use of aluminum improves rigidity and durability greatly. The alumite treatment enhances the surface of the funnel and gives it a sleek black appearance. Suction pipe design for a certain vehicle. The angle and length of the pipe boost the induction efficiency. It provides quick reactions for NA engines and increased performance for turbocharged engines. With a standard suction system, induction air hits the corrugated portion of the hose, causing swirl and resistance. The carefully built pipe lowers the corrugated area and the gap inside the pipe to improve airflow. Replacing all relevant pieces between the HKS air cleaner assembly and the throttle (to the compressor housing on turbo cars) allows for reducing air intake limits and boosting air intake efficiency, offering a major improvement in engine responsiveness and performance. Exclusively for some vehicles only, a direct type Super Power Flow air cleaner assembly is offered. It ensures that air flows smoothly from the filter’s entrance point to the throttle valve.
