Information
Engine mount kit.
This OE Match engine mount kit is designed for Porsche 997 MK1 Carrera Cabriolet and Targa models with 3.6L and 3.8L engines. The set includes two OE Match hydraulic engine mounts along with the correct genuine Porsche bolts and nuts required for proper installation. Engine mounts secure the engine to the vehicle chassis while isolating vibrations and maintaining correct drivetrain alignment during operation.
SET OF 2 with bolts and nuts
Fits:
Porsche 997.1 Carrera 3.6L / 3.8L 2005 - 2008 CABRIO
Porsche 997.1 Carrera 3.6L / 3.8L 2005 - 2008 TARGA
Diagram Ref No 2, 3 and 5.
Kit Includes:
2 × OE Match Engine Mount – 99737504907
4 × Genuine Porsche Hexagon-head bolt – 90037805501
2 × Genuine Porsche Hexagon nut M12 × 1,5 – 99908421501
This complete kit allows both engine mounts to be replaced at the same time, ensuring balanced support and proper engine positioning.
Engine mounts stabilise the powertrain and isolate engine vibration from the chassis and passenger compartment. By controlling engine movement during acceleration, braking and cornering, they help maintain smooth driving characteristics and protect other drivetrain components from excessive stress.
Replacing worn mounts restores engine stability and improves ride comfort.
Function
• Engine Support: Secures the engine to the chassis structure
• Vibration Isolation: Hydraulic design reduces engine vibration transmitted to the cabin
• Alignment Stability: Maintains correct engine and drivetrain positioning
• Ride Comfort: Helps ensure smooth and quiet vehicle operation
Engine mounts are exposed to constant load, heat and vibration. Over time the hydraulic fluid and rubber components can deteriorate, allowing excessive engine movement. This can lead to increased vibration, noise, and stress on the drivetrain. Replacing both mounts together ensures balanced support, restores smooth engine operation and protects surrounding components.
Replace engine mounts if you notice:
• Increased vibration inside the cabin
• Clunking or movement during acceleration or gear changes
• Engine movement when revving
• Visible cracking or collapse of the mount

Information
Engine mount.
This Porsche Genuine OE Engine Mount (Part No. 99737504908) is a factory-engineered hydraulic engine mount designed to secure the engine assembly to the chassis of Porsche 911 (997) models. Manufactured to Porsche’s strict original equipment standards, this mount ensures the correct balance of structural support and vibration isolation required for Porsche’s high-performance flat-six engines.
Sold each, 2 required per vehicle.
Fits:
Porsche 997.1 Carrera 2005 - 2008 COUPE
Porsche 997.1 Turbo 2007 - 2009 COUPE
Porsche 997.2 Carrera 2009 - 2012 COUPE
Porsche 997.2 Turbo 2010 - 2013 COUPE without PADM (dynamic engine mounts)
Diagram Ref No 2.
This mount is supplied as a single unit (sold individually) and is suitable for both left and right sides of the engine mounting assembly. Two mounts are typically required per vehicle.
Old Porsche part numbers: 99737504904, 99737504906
The engine mount forms the connection between the engine block and the vehicle chassis. Its hydraulic internal structure absorbs engine vibrations while maintaining proper drivetrain alignment.
By controlling engine movement during acceleration, braking, and cornering, the mount helps maintain smooth engine operation, stable handling, and reduced vibration inside the cabin. Hydraulic mounts are specifically designed to dampen engine oscillations and road shock, contributing to the refined driving characteristics expected from a Porsche sports car.
Functions & Technical Role
• Engine support: Secures the engine assembly to the chassis structure
• Hydraulic vibration damping: Reduces noise, vibration, and harshness (NVH)
• Powertrain stability: Limits excessive engine movement during driving loads
• Alignment control: Maintains correct engine and transmission positioning
• OEM precision fit: Designed to Porsche factory geometry and mounting specifications
Fitment / Position on Car
• Fitting position: Engine mounting assembly
• Location: Between the engine bracket and rear subframe/chassis mount
• Orientation: Fits left or right side of the engine (two mounts per vehicle)
Engine mounts are subjected to constant stress from engine torque, heat, and vibration. Over time, the rubber and hydraulic elements can deteriorate, leading to:
• Increased engine vibration or noise in the cabin
• Excessive engine movement during acceleration
• Harsh drivetrain behaviour or reduced ride comfort
• Premature wear of surrounding drivetrain components
Replacing worn mounts with genuine Porsche OE components restores the original balance of comfort and performance designed for the 997 platform.

Porsche 997
Solid engine mounts are a smart upgrade to any track or aggressive street car, and were installed on Porsche factory race cars. Stock mounts are made of compliant rubber, and contribute to imprecise shifting and inferior throttle response. Solid mounts create slightly more interior vibration than rubber mounts, but securely connect the engine and transmission assembly to the car's unibody, creating a crisper throttle response and shifter feel. Rennline's solid mounts are CNC machined from 6061 aluminum for strength and light weight, and come as a pair with new Grade 8 mounting hardware. Sold as a set of (2)
