Turbosmart BLOW OFF BMW 135I 335I Z4 N54 Dual Port Kit TS-0203-1050

BOV valve with double outlet. The Kompact Dual Port opens up into the atmosphere and goes back to the intake. Sequential synchronization ports allow for quieter operation during normal driving while offering the performance and sound of BOV firing into the atmosphere under heavy loads. Standard valves made of plastic, as opposed to the very strong machined aluminum Kompact structure. In standard valves, plastic becomes brittle with age and can crack, causing severe blow-bys. This prevents the turbo from reaching its full capacity, depriving you of performance. With its anodized aluminum body and lightweight alloy piston, the Kompact offers extreme durability, excellent response and excellent pressure-holding capability in a small package. The Kompact Dual Port is ideal for owners of vehicles with light weight modifications and looking for the classic vent-to-atmosphere BOV sound in the original OEM replacement housing Fits: BMW 135I (2008-2013) BMW 135IS (2013) BMW 335I (2007-2015) BMW 335IS (2011-2013) BMW Z4 ( 2014-2016) Dual outlet-type BOV. The Kompact Dual Port vents both to the atmosphere and back into the air intake. Ports with sequential timing allow quieter operation during normal driving, while still offering the performance and sound of a vent-to-atmosphere BOV when the going gets harder. & Nbsp
