RSD BMW 335/135 Intake Pipe w/ Blow-off Valve

Designed specifically for the BMW 335i/135 (N54) turbocharged applications, the RS Design Charge Blow-Off/ Diverter System prevents compressor surge which can be detrimental to the longevity of the turbo(s). Utilizing a unique design that allows for crisp throttle response and increase turbo spool – the RSD Charge Kit will vent excess charged air through the use of a HKS SSQV (Super Sequential Blow-Off Valve) which uses a pull type relief valve. The SSQV is actuated by pressure alterations only, ensuring quick valve response and complete closure during idle. The SSQV utilizes two valves to offset and balance the charged air and increase efficiency. Smooth mandrel bends and a step design ease airflow into the throttle body.


As the excess charged air is vented to atmosphere or re-circulated *(RSD optional kit), the concern of air being fed back to the compressor house causing potential damage to the turbine and its cartridge is minimized. This is a complete bolt-on kit and no modifications are needed. The RSD Charger kit will fit most popular aftermarket intakes. Kits are offered in tasteful color options.
