HKS Airflow Less Adaptor SR - HKS1599-SN002

is an aluminum piping component designed to remove the stock airflow meter on Nissan Silvia S13/S14/S15 and 180SX models equipped with SR20DET/SR20DE engines. It is used for D-Jetro (MAP sensor-based) conversions, improving suction efficiency, and often paired with HKS F-CON V Pro management.

Features:

• Application: Nissan Silvia/180SX (S13, S14, S15) with SR20 engines
• Material: Buffing-finished aluminum cast pipe
• Purpose: Replaces the stock air flow meter to reduce suction resistance
• Sensor Provision: Includes a boss to install an intake air temperature sensor (requires modification)

Air flow meter is one of big suction resistance. It can be removed as D-Jetro and controlled with "F-CON V Pro". Performance is greatly improved when Racing Suction Reloaded is also installed. With "Air Flow Less Adapter", air flow meter can be easily removed. Buffing finished aluminum cast pipe can be replaced with air flow meter. There is a boss on the pipe to install intake air temperature sensor (Modification is required).
