This Porsche Genuine OE Dynamic Engine Mount is an original-equipment active drivetrain mount engineered to Porsche’s factory specifications for the Porsche 718 Boxster and 718 Cayman (982). This mount forms part of the Porsche Active Drivetrain Mount (PADM) system, designed to dynamically control drivetrain movement and vibration depending on driving conditions.

It is supplied as a single mount (sold individually) and fits both left and right sides of the drivetrain assembly. Two mounts are typically required per vehicle.
Engine and gearbox mounts secure the powertrain assembly to the vehicle chassis while isolating vibrations and controlling drivetrain movement. In models equipped with PADM, the mount can adjust stiffness electronically depending on the selected driving mode or driving dynamics.
During normal driving the mount remains softer to absorb vibrations and improve ride comfort. Under aggressive acceleration or sport driving, the mount stiffens to reduce engine movement and improve handling precision and power transfer.
Engine mounts experience continuous stress from engine torque, vibration, and thermal cycles. Over time, the internal hydraulic and electronic elements can wear, leading to:
• Increased engine vibration in the cabin
• Excess drivetrain movement under load
• Reduced handling precision
• Potential warning messages from the PADM system
Replacing worn mounts with a genuine Porsche OE mount restores the factory driving dynamics, vibration isolation, and drivetrain stability engineered for the 718 platform.

The Genuine Porsche OE Engine Mount 982399201A is a direct replacement for the standard (non-dynamic) engine mount on Porsche 718 Boxster and Cayman models. It offers the correct vibration isolation, stiffness, and durability to maintain smooth engine operation, comfortable ride quality, and proper powertrain alignment.

An engine mount’s primary function is to secure the engine to the vehicle’s chassis while absorbing and isolating vibration and torque reaction forces. The 982399201A is tailored for standard (non-dynamic) mount applications, offering consistent support and comfort without the adaptive hydraulic elements found in dynamic mount systems. It maintains alignment between the engine and transmission, controls engine motion under acceleration and deceleration, and helps prevent excessive vibration transfer to the cabin.
Functions & Technical Role Engine support:
• Holds the engine securely in place within the chassis
• Vibration isolation: Reduces the transfer of engine noise and vibration into the cabin
• Torque reaction control: Helps manage engine movement during acceleration, deceleration and gear changes
• Correct OE stiffness: Engineered material durometer and geometry for non-dynamic mount applications
• Direct fit: Porsche-matched mounting points, bushings and hardware interface
Fitment / Position on Car:
• Installed on: Engine-to-chassis interface
• Location: One of the front or rear engine mounting points (per factory diagram — often one per side of crankcase on 718 models)
• Orientation: Mounts between cast engine bracket and chassis frame/bracket
Engine mounts are critical to both vehicle comfort and mechanical integrity. As rubber and bonding materials age, mounts can harden, crack, or break - leading to:
• Increased engine noise in the cabin
• Harsh vibration or shaking at idle
• Excessive engine movement under load
• Accelerated wear on adjacent components
Replacing worn mounts with a genuine Porsche OE mount like the 982399201A ensures the correct stiffness and isolation characteristics - avoiding the fitment issues, noise problems, and accelerated wear.
