Turbo Charger Seal Ring Kit

This is a resonator seal kit for the OM642 Sprinter van 2007-2009 (pre BlueTec)
This kit includes:
Turbo Charger Seal (017 997 04 45) [ORANGE SEAL]
Turbo Charger Seal (014 997 64 45) [GREEN SEAL]
Trubo Charger Seal Ring (000 094 00 51) [BLACK SEAL]
 
It is recommended to replace all seals when replacing/removing/installing your resonator.
The orange seal goes between the clean air intake from the air filter into the turbo. It is commonly and easily damaged. Once it becomes too damaged, chunks of it can be actually sucked off of it and into the turbo, causing damage to the turbo itself and everything downstream of it. It should be replaced anytime it shows signs of wear and especially if it shows any signs of tearing or ripping.
The Black seal goes on the inlet side of the resonator and the green seal goes on the outlet side of the turbo, also called the hot side. All of the seals are crucial and maintaining your turbocharged system tight and free of any leaks which will rob you of power and could put you into limp mode.
