HKS Airflow Less Adaptor for Nissan Skyline GT-R (R32/R33/R34) - 1599-SN003

$132.00

Fits 1989-2002 Nissan Skyline GT-R R32, R33, and R34 models equipped with the RB26DETT engine.

The HKS Airflow Less Adaptor (1599-SN003) is an essential component for high-performance builds converting to a Speed Density or MAP-based engine management system. In a factory RB26 configuration, the mass air flow (MAF) sensors can create physical intake restrictions as boost levels and power demands increase. This HKS adapter replaces the factory sensor housing with a straight-through design, eliminating that bottleneck and allowing for smoother, unrestricted airflow to the turbochargers.

Constructed to precise tolerances, this adapter ensures a secure, leak-free connection between the air intake and the turbocharger inlet pipes. It is specifically designed for use with standalone ECUs, such as the HKS F-CON V Pro, which calculate engine load without the need for a physical airflow meter.

  • Manufacturer Part Number: 1599-SN003
  • Replaces factory 80mm MAF sensor (OE 22680-05U00)
  • Engineered for RB26DETT twin-turbo applications
  • Cast construction for durability and consistent fitment
  • Direct bolt-on flange design to simplify Speed Density conversion
