Engine mount kit
The OE Match Engine Mount Kit is a complete replacement solution for Porsche 993 Carrera 4 / 4S Cabriolet models. It includes two OE Match engine mounts along with genuine Porsche bolts, washers, and locknuts required for secure installation.
SET OF 2, with bolts, washers and nuts
Fits:
Porsche 993 (911) C4 / C4S 1994 - 1997 Cabrio
Diagram ref no 7, 8, 9 and 10
This comprehensive kit is designed to replace both engine mounts and associated hardware in one complete package.
Kit includes:
• 2 × OE Match engine mounts (99337504909)
• 4 × Genuine Porsche bolts (90007413402)
• 4 × Genuine Porsche washers (96437511001)
• 2 × Genuine Porsche locknuts (99908421501)
The mounts are manufactured to OE specifications, ensuring precise fitment and proper vibration damping. These hydraulic-style mounts are engineered to support the engine while absorbing movement and reducing drivetrain vibration.
Including genuine Porsche fixings ensures correct torque, alignment, and long-term reliability - eliminating the risks associated with reusing old or stretched hardware.
This kit stabilises the engine within the chassis while isolating vibration and controlling engine movement. It restores smooth operation, improves driving comfort, and ensures proper drivetrain alignment.
Replacing both mounts and hardware together provides a complete refresh of the engine mounting system, eliminating common causes of vibration and noise. Engine mounts are specifically designed to reduce drivetrain vibration and maintain stability
Function
• Supports and secures the engine in position
• Absorbs vibration and reduces cabin noise
• Maintains proper drivetrain alignment
• Ensures secure installation with OE-spec hardware
This kit is essential for maintaining both performance and refinement in classic Porsche models.
Over time, engine mounts degrade due to heat, load, and fluid wear, leading to increased vibration and engine movement. Worn mounts can negatively affect handling, comfort, and even stress surrounding components. Replacing both mounts together with new genuine hardware ensures proper installation, restores factory-level smoothness, and protects the drivetrain from further wear.
When to replace
• Increased vibration in cabin or steering
• Clunking during acceleration or gear changes
• Visible wear or fluid leakage from mounts
• Engine sitting lower or misaligned
• During engine or gearbox service
