Information
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

Manufactured to OE specifications for fit, function and durability, this replacement engine mount combines robust metal construction with a resilient rubber damping element to provide the ideal balance of support and vibration isolation. It is an essential component for maintaining driving comfort, drivetrain alignment and overall vehicle reliability.
What This Product Does:
- Supports and secures the engine within the chassis.
- Absorbs and dampens engine vibration.
- Reduces the transmission of noise into the passenger compartment.
- Maintains correct engine alignment and positioning.
- Controls engine movement during acceleration, braking and cornering.
- Helps protect drivetrain and exhaust components from excessive stress.
Symptoms Of Wear Or Failure:
- Increased engine vibration felt through the cabin.
- Clunking, knocking or thumping noises during acceleration or gear changes.
- Excessive engine movement when accelerating or decelerating.
- Harsh drivetrain engagement.
- Visible cracking, splitting or deterioration of the rubber mount.
- Sagging or misaligned engine position.
- Increased noise levels from the engine bay.
- Premature wear of adjacent drivetrain or exhaust components.
Why Replacement Matters:
- Engine mounts are subjected to continuous engine vibration, drivetrain torque, road shock, heat and environmental exposure. Over time, the rubber damping material can harden, crack, compress or separate from the mount housing, reducing its ability to properly support and isolate the engine.
- A failed engine mount can allow excessive engine movement, leading to increased vibration, poor driving refinement and additional strain on transmission mounts, exhaust systems, hoses and drivetrain components. If left unchecked, this can contribute to accelerated wear and costly repairs elsewhere in the vehicle.

Engine mount
Replaces OEM part number:
477199301 (left) and 477199303 (right)
Fits:
Porsche 924
Replaces both the conventional rubber (LHS) and steel spring (RHS) mounts on the 924 with a durable rubber inserted mount in a strong steel cage giving a direct replacement for the originals. The mount design controls engine movement by less deflection than the original thereby giving the car a 'tighter' feel and reducing stress on exhaust and other ancilliaries under 'performance' driving conditions.
Pleas note: usage of these mounts give an tighter/sportier feel which will have an slight effect on driver comfort on an urban driving cycle.
PRICE IS FOR SINGLE MOUNT
