BMW E82/88 135i Blow Off Valve Kits
The BMW N54 engine is highly responsive to performance upgrades, particularly those that maximize the effectiveness of its advanced turbocharging system.
Two blow-off valve kits enhance boost pressure stability while more quickly releasing unwanted boost into the atmosphere.
An ECS-engineered and Synapse kit are available, both including an atmospheric vent blow off valve, black anodized intake tube with machined flange, durable silicone hose coupler, block-off caps for the stock diverter valve recirculation, and all required clamps and hardware to complete the project.
