Gasoline engine
Removal
1. Pull the intake air temperature sensor (B17) out of the cross pipe by squeezing the retaining clips (arrow).
2. Screw on the clamps (4/8), (4/13) and remove the air filter cross pipe (4/5) together with the fitting hose (4/6).
Installation
1. 4-cylinder engine: Position the air cleaner cross pipe so that both base elements on the bottom are pressed into the retaining lugs on the high-voltage cable housing (arrows).
2. 6-cylinder engine: Fit the air cleaner cross pipe so that the welded hollow pins are pressed into the rubber bearings of the cylinder head cover. The hollow pins serve to ventilate the engine crankcase and to fix the cross pipe.
3. Tighten the hose clamps firmly.
4. Install the intake air temperature sensor (1B17) and press the retaining clips outward until they click into place.
