Here is a better description. It might be called the flame trap? On the right, back side of the engine, the plastic tubing for the air intake go into the turbocharger. On the air intake, right before the turbo charger, there is a fitting. Two tube come out of it, a regular rubber tube and a smaller harder, flexible plastic tube. The plastic tube comes to a little rubber mount at the fitting on the air intake, this is broke, so I need to replace the whole tube as it seems, since I cant just replace the rubber mount. The tube runs up to the front of the engine, and under the intake manifold and fuelrail, it is insulated as well. I just want to know how to replace this, and where is the other end. I hope that helps. Thanks!
