Review on 🔧 Compatible Air Supply Valve Block for Mercedes Benz 2007-2015 W164 W166 W221 W251 GL Class 2123200358 2513200058, Air Suspension Compressor by Jason Wright

Quality is like the original part. Ease of installation. Works very well, withstands pressure according to the test carried out on the Mercedes Star diagnostic computer (but is not required for installation). The exhaust valve is quite noisy compared to the original Mercedes part. I've had it for a few months now and it works fine.
