Why Replace It, Engine mounts are crucial for:
• Locating and supporting the engine
• Absorbing vibration and engine torque under acceleration, braking, and cornering
• When this mount deteriorates or fails, you can expect, Increased vibration transmitted to the cabin, steering, or pedals
• Clunks, bangs, or loud noises during acceleration, deceleration, or gear changes from engine movement against the chassis
• Visual signs such as leaking black fluid from the mount, sagging of tailpipes (due to dropped mounting), or visible damage to rubber or metal components
Common Failure Causes:
• Age-related rubber degradation: over time, rubber hardens, cracks or de-bonds, causing loss of damping and allowing engine movement
• Fluid leakage (hydraulic version): loss of damping fluid due to seal failure accelerates failure
• Fluid contamination: oil, coolant, or other contaminants degrade the rubber material
• Vehicle abuse or stress: aggressive driving, hard launches, or previous accidents can warp or break mounts
• Worn or cracked brackets: even if the rubber is intact, the aluminium bracket can be damaged or corroded, reducing effectiveness

Information
Engine mount.
This OE Match engine mount is a hydraulic engine mounting component designed for Porsche 911 (996) models. Manufactured to match the original Porsche specifications, it provides secure engine support while reducing vibration transmitted to the chassis. This mount is a direct-fit replacement for the factory engine mount used in the 996 drivetrain system.
Sold individually, two are required per vehicle.
Fits:
Porsche 996 C2 / C4 3.4L 1997 - 08/2001
Porsche 996 C2 / C4 3.6L 09/2001 - 2005
Porsche 996 C4S 3.6L 09/2001- 2005
Diagram ref no 2.
This mount replicates the original Porsche design to ensure proper fitment, durability and vibration damping. It replaces earlier versions such as 99337504905 and 99337504906, offering improved reliability and performance.
The engine mount stabilizes the engine and limits excessive movement during acceleration, braking and cornering. By absorbing vibration and engine torque, it helps maintain smooth driving characteristics and reduces noise or vibration transmitted to the cabin.
Replacing worn mounts restores drivetrain stability and helps protect surrounding components such as the exhaust system, transmission and driveshaft.
Function
• Engine Support: Secures the engine to the chassis or engine cradle
• Vibration Isolation: Hydraulic mount design absorbs engine vibration
• Drivetrain Stability: Controls engine movement under load
• Noise Reduction: Minimizes vibration transmitted to the cabin
Engine mounts are subjected to constant vibration, engine torque and heat. Over time the rubber and hydraulic components can degrade, reducing their ability to absorb movement. This may result in increased cabin vibration, clunking noises during gear changes, or visible engine movement. Replacing worn mounts restores proper engine support and ensures stable drivetrain operation.
Consider replacing the engine mount if you notice:
• Excessive engine vibration inside the cabin
• Clunking or knocking during acceleration or gear changes
• Visible hydraulic fluid leakage from the mount
• Sagging exhaust or engine position changes

Engine mounts
This OE Match engine mount kit provides a complete replacement solution for the engine mounting system on Porsche 911 (996) Carrera 2, Carrera 4 and Carrera 4S models. The kit includes two OE Match hydraulic engine mounts along with the correct OE Match bolts and genuine Porsche locknuts required for secure installation.
SET OF 2, with bolts and nuts.
Fits:
Porsche 996 C2 / C4 3.4L 1997 - 08/2001

Kit Includes
2 × OE Match Engine Mount – 99337504908
4 × OE Match Hexagon Bolt – 90037805501
2 × Genuine Porsche Locknut M12 x 1.5 – 99908421501
Replacing both mounts together ensures balanced engine support and restores the original vibration-damping characteristics of the drivetrain.
The engine mounts stabilise the engine and isolate vibration from the vehicle body. They maintain the correct engine position during acceleration, braking and cornering, helping ensure smooth power delivery and reducing noise or vibration transmitted to the cabin.
Replacing worn mounts restores drivetrain stability and improves driving comfort.
Function
• Engine Support: Secures the engine to the chassis structure
• Vibration Isolation: Hydraulic mount design absorbs engine vibration and noise
• Drivetrain Stability: Maintains correct engine alignment under load
• Component Protection: Reduces stress on transmission, exhaust and drivetrain components
Over time, engine mounts can deteriorate due to heat, vibration and repeated load cycles. When the hydraulic damping material weakens or leaks, excessive engine movement can occur. This often results in increased cabin vibration, knocking noises during gear changes or visible sagging of drivetrain components.
Replacing the mounts with a matched pair restores proper engine support and ensures smooth, stable operation of the drivetrain.
Replace the engine mount kit if you notice:
• Excessive vibration in the cabin or steering wheel
• Clunking during acceleration or gear changes
• Engine movement when revving the engine
• Visible fluid leakage or cracked mount rubber
