CTS Turbo BMW N54 Blowoff Valve Installation Kit with Meth Bung

Transform your BMW N54’s intake tract with this CTS Turbo charge pipe and dump valve conversion package. Engineered for enthusiasts who want reliability and sound, this uprated boost pipe replaces the fragile factory plastic and failure-prone OE diverter valves with a high-strength mandrel-bent T6 6061 aluminium hard pipe. It delivers an OE-style fit with a more aggressive vent-to-atmosphere whoosh when paired with a TiAL Q unit. Perfect for tuned N54 setups seeking better boost holding under heavy load and a sharper, motorsport-inspired soundtrack.

We have installed this in-house at MJ Modifications and the results speak for themselves. Customers love the robust build, the clean fitment and the instant improvement in confidence under boost. If you want a dependable upgrade that looks the part and performs, this is it.
