Removing
1. The air block, if equipped, is attached with two or three bolts to the top of the throttle body. Pay attention to the direction and connections of the vacuum pipes of the inlet air temperature control system.
2. Disconnect the engine breather hose from the air block, and the vacuum pipe from the coupler at the rear of the throttle body (see illustration).
3. Do not lose the O-ring when removing the air unit.
Installation
4. When installing, check that the O-ring is correctly placed in the groove on the back of the air unit; tighten the screws and connect the vacuum pipe and breather hose (see illustrations).
