CTS Turbo BMW N54 Blowoff Valve Kit with Meth Bung
Ditch the flimsy factory charge piping and failure-prone diverter valve on your N54. This CTS Turbo BOV kit is built exclusively for the TiAL Q atmospheric blow-off valve (sold separately), pairing OEM-like fitment with an unmistakable aftermarket whoosh. Better looks, better boost control under heavy load.
