This is a product unique to HKS that makes it possible to install a blow-off valve in a valvetronic engine that does not generate negative pressure in the intake manifold. When open to the atmosphere, the high-frequency and sharp operating sound peculiar to the SUPER SQVIV greatly appeals its existence. By changing the genuine resin charge pipe part to an aluminum pipe, we have improved durability and reduced ventilation resistance (see below). The set items with the suction return kit are set exclusively for vehicles equipped with a genuine air cleaner and for vehicles equipped with a carbon racing suction/cold air intake.
