Blow Off Valve (BOV) Adaptor for the Mercedes 1.6-2.0 Μ270 and Μ274 Turbo engines (DE16LA 1600cc 156PS and DE20LA 2000cc from 156 to257PS as found on many models as A Class W176 (2012-2018), B-Class W246 (2011-2018), CLA Class C117 (2013-2019), GLA Class X156 (2015-2019), GLC Class X253 (2015-2019).
The spacers were developed to produce the great atmospheric BOV sound that is expected from your turbocharged vehicle, although normally lacking on your vehicle. This CNC machined spacer, made from solid billet aluminium, gives you that sound you have been looking for. When letting off the throttle you get that sweet and satisfying “whoosh” letting everyone know your Mercedes is in fact turbocharged.
It has been designed to work with the original electrically controlled solenoid and utilises high quality o-rings for a perfect seal.
