The intake hose cracks with age, and especially the GTS intake hose which is sort of insulated deteriorates badly over time.

By the way, the original intake hose is super light weight.

The hose of a S4 fits and is still available.

These is a nice alternative to the Porsche s4 hose is a combination of a few hoses that Mercedes uses.

Ok, need to buy 4 tubes and 2 and 3" (76mm) Blue or black Silicone Hump Couplers.

From a ML560 SEL


Fils MB model M116 or M117
'90 560 SEL

The Mercedes 560 intake hoses coupled together with a few inches of 3" silicone hose was not a precision fit.

Mercedes Benz 117 094 03 82
13 5/8" long (35,6cm), 3 1/4 (8,2) and 3" (7,6cm) ID, smooth on both ends with three bellows sections 2 1/4" (5,7cm) long, with 1 1/2" (3,8cm) smooth sections between them. Trimming off most of the smooth large end section puts a smooth spot very close to the TB vent so a hole is easy to cut.

They are Mercedes Benz tubes. They are cut after the 3rd set of rings and a silicone tube is used for additional flexibility.

This is what it looks like in my engine bay.




This is the coupler with a buffer for movement. It is a matter of taste I think...
