Removing the Stock Intake System

Before starting the installation of the AFE MagnumFORCE Intake Stage-2 Pro DRY S on your 2017 BMW 340i, it is crucial to safely and properly remove the stock intake system. This process involves several meticulous steps that need to be followed to prevent any damage to delicate components.

First, ensure the engine is completely cool. Begin by loosening the clamps that secure the intake tubing. These clamps are usually located near the throttle body and airbox. Use a flathead screwdriver or a socket wrench to carefully loosen them. Once the clamps are loose, you can gently pull the tubing away from the throttle body and airbox.

Next, disconnect any sensors attached to the intake system. The 2017 BMW 340i’s stock intake system typically includes a mass airflow (MAF) sensor. Carefully unplug the sensor by pressing down on the connector tab and pulling it away from the sensor. Avoid using excessive force to prevent damaging the connector or the sensor itself.

After disconnecting the sensors, proceed to remove any screws or bolts holding the intake system in place. These fasteners are usually located around the airbox and along the intake tubing. Use the appropriate tools, such as a socket wrench or screwdriver, to remove them. Keep track of all screws and bolts by placing them in a small container to avoid misplacing them.

With the clamps loosened, sensors disconnected, and fasteners removed, you can now carefully lift the stock intake system out of the engine bay. Be mindful of any remaining connections or components that might still be attached. Gently maneuver the intake system to avoid hitting or damaging other engine parts.

Store the removed stock intake system in a safe and clean area. If you plan to re-install it in the future, ensure all components are kept together and in good condition. Following these steps will ensure a smooth transition to installing the AFE MagnumFORCE Intake Stage-2 Pro DRY S, enhancing your BMW 340i’s performance with minimal risk of damage to existing components.
