HKS Racing Suction Cold Air Intake Kit Racing Black Short Ram Suction Reloaded Kit by HKS®. With stock suction system, induction air hit to corrugated portion of hose and makes swirl and resistance. The specially designed pipe reduces corrugated portion and gap inside pipe to make air flow smoother.

Features:

• Kit includes Super Power Flow and Aluminum Suction pipe. Polished aluminum pipe improves engine room appearance.
• Enjoy a distinctive induction sound.
• Improving an air intake efficiency, HKS changed from flexible stock rubber hose to aluminum pipe. This significantly reduces an airflow restriction at an HKS flow bench test compared to the stock intake system.
• Removable air duct (air guide) which has a wide opening is newly designed. This can be directly used stock ECU even for the normal vehicle or the vehicle with a custom muffler. You can reduce more air intake resistance, removing the air guide.
