Engine mounts are essential for supporting the engine while isolating vibration and maintaining proper drivetrain alignment.
Kit Includes
2 × OE Match Engine Mount – 99737504908
4 × OE Match Hexagon Bolt – 90037805501
2 × Genuine Porsche Nut – 99908421501
This kit contains everything needed to replace both engine mounts during servicing or drivetrain maintenance.
Engine mounts stabilise the engine and prevent excessive movement during acceleration, braking and cornering. By isolating vibrations and maintaining the correct drivetrain alignment, they help ensure smooth engine operation and improve overall driving comfort.
Replacing worn mounts restores the vehicle’s original ride quality and helps protect surrounding components such as the transmission, exhaust and drivetrain mounts.
Function
• Engine Support: Secures the engine to the chassis and rear subframe
• Vibration Isolation: Hydraulic design absorbs engine vibration and noise
• Drivetrain Stability: Maintains correct engine alignment during load changes
• Component Protection: Reduces stress on transmission and exhaust components
Engine mounts are exposed to continuous heat, vibration and engine torque. Over time the rubber and hydraulic components can deteriorate, leading to increased engine movement, cabin vibration and knocking noises during acceleration or shifting.
Replacing worn mounts with a matched OE Match set restores proper engine stability, improves driving refinement and helps extend the life of surrounding drivetrain components.
Replace the engine mounts if you notice:
• Increased vibration inside the cabin
• Clunking or knocking during acceleration or gear changes
• Excessive engine movement when revving
• Visible wear, cracking or leakage from the mount
