Weistec M133 Anti Surge Valve Mercedes-Benz C117 CLA45 AMG 2014-2019
$349.00

Transform Your Turbocharged Experience

Every high-performance turbocharged engine needs a reliable pressure release system. If you own an AMG with the powerful M133 engine, you might have noticed a significant drawback: the absence of a bypass valve. This missing piece can lead to compressor surge and, over time, cause serious damage to your turbo. Let's talk about how we can solve that!

Introducing the Weistec Anti-Surge Valve (ASV)

The Weistec Anti-Surge Valve is designed with one goal in mind: to prevent compressor surge and protect your turbo system from premature wear. By venting compressed air to the atmosphere instead of allowing it to flow back into the compressor housing, this valve helps maintain the health of your turbocharger. Continuous backflow can negatively impact essential turbo components, slowing down the impeller wheel and requiring it to "respool" every time you hit the throttle.

Benefits of the Weistec ASV

With the Weistec ASV, not only will you extend the life of your turbocharger, but you'll also enjoy improved throttle response and quicker spool-up times. Plus, who doesn't love that iconic "blow-off" sound? This upgrade is perfect for anyone looking for a straightforward, bolt-on solution or those planning to enhance their AMG 45 vehicle down the line.

Key Features

  • 100% Bolt-on solution
  • No check engine light
  • Easy installation in just 30 minutes
  • Increased lifespan of turbo
  • CNC machined aluminum for durability
  • Hard anodized to military specifications
  • Engineered and manufactured in the USA
  • Compatible with Engine: M133

Fitment

  • Mercedes-Benz X156 GLA45 AMG (2014-2019)

Important Note

  • If you have a later model, it may come with an electronic bypass valve from Mercedes. This valve just needs to be removed and relocated while still plugged in, and the Weistec ASV will work perfectly as intended.
  • Dimension: 7x4x4

What Is Weistec Engineering?
