Atmospheric Blow Off Valve For Mercedes AMG A45 GLA45 CLA45 M133 2.0T

Bolting this atmospheric blow off valve into your pre-facelift A45, GLA45, or CLA45 solves the throttle hesitation that often follows a performance tune or hard track driving. The valve connects directly to the blanked-off factory port on your M133 turbocharger, releasing pressure immediately when you lift off the gas. This smooth transition prevents turbo stall and keeps boost steady, protecting your engine during aggressive shifts.

Benefits & Tips

Enjoy that classic compressor flutter sound every time you close the throttle, thanks to the vent-to-atmosphere design. Keep the mechanism clean by removing the valve occasionally, as the anodized aluminum housing makes disassembly simple without special tools. When tuning your ECU, pair this install with a custom blow-off map to eliminate hunting surges during downshifts.
