HKS Premium Suction Air Intake Kit for 2009-2010 Nissan GT-R R35

The HKS Premium Suction kit features an aluminum polished finish and is designed to reuse the stock blow-by pipes. The inner diameter of HKS' specially designed cast aluminum suction pipe is 53mm compared with stock 45mm. By increasing the inner pipe diamter, restriction of intake air flow is reduced by about 12% resolving the inevitable bottle neck effect at high boost level.
