So you are looking to get that incredible turbo whoosh sound from your Mercedes 2.0L or 3.0L turbocharged engine? Well, the new VR Performance billet aluminum blow-off valve spacer is the way to go. Cars like the Mercedes CLA250, A250, GLA250 only use 1 valve where the 3.0T V6 turbo uses 2 valves. The blow-off valve spacer goes between the turbocharger and the factory pressure relief valve.
