Mercedes CLS55 AMG W219, Replacing The Old SAI Hoses

Decided to replace the 2 old Secondary Air Injection (SAI) hoses on the front of the big V8 M113k engine. As I pulled them of, they started to deteriorate, so I was just in time. The SAI system helps the catalysts heat up faster in a cold start situation.
