Engine Mounts
By OE Match
- Porsche 997 MK1 TURBO 2007-09
This OE Match engine mount kit is designed for the Porsche 911 (997 MK1) Turbo Cabriolet. The kit includes two OE Match hydraulic engine mounts along with the correct genuine Porsche bolts and nuts required for a secure and factory-style installation. Engine mounts play a crucial role in supporting the engine and isolating vibration, ensuring smooth drivetrain operation and maintaining proper engine alignment within the chassis.
SET OF 2 with bolts and nuts
Fits:
Porsche 997.1 Turbo 2007 - 2009 CABRIO
Diagram Ref No 2, 3 and 5.
Kit Includes:
2 × OE Match Engine Mount – 99737504907
4 × Genuine Porsche Hexagon-head bolt – 90037815901
2 × Genuine Porsche Hexagon nut – N90848405
This set provides all the main components needed to replace both engine mounts during maintenance or drivetrain servicing.
The engine mounts stabilise the engine and limit excessive movement during acceleration, braking and gear changes. Their hydraulic construction absorbs vibration and reduces noise transferred to the chassis, helping maintain smooth driving characteristics and protecting surrounding drivetrain components.
Replacing worn mounts restores correct engine positioning and improves overall driving comfort.
Function
• Engine Support: Secures the engine to the chassis structure
• Vibration Isolation: Hydraulic design reduces engine vibration and noise
• Drivetrain Stability: Maintains proper engine alignment during load changes
• Component Protection: Reduces stress on exhaust, transmission and drivetrain components
Engine mounts are exposed to continuous heat, vibration and load cycles. Over time the hydraulic fluid and rubber components can deteriorate, leading to excessive engine movement, vibration or knocking sounds during acceleration and gear changes.
Replacing the mounts with a matched pair restores proper engine stability, improves ride comfort and helps protect drivetrain components from unnecessary wear.
Consider replacing the 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

The engine mount is a structural component that secures the engine assembly to the vehicle’s rear subframe. Porsche uses hydraulic engine mounts in the 997 Cabrio and Targa models to absorb vibrations and control engine movement during driving.
This OE Match engine mount is engineered to meet original specifications for fit, strength and vibration damping, ensuring proper engine positioning and reliable long-term performance.
The engine mount stabilises the engine and prevents excessive movement during acceleration, braking and gear changes. Its hydraulic design helps reduce vibration and noise transmitted to the cabin, improving driving comfort and protecting surrounding drivetrain components.
Replacing worn mounts restores correct engine alignment and smooth drivetrain operation.
Function
• Engine Support: Secures the engine to the chassis structure
• Vibration Isolation: Hydraulic design reduces engine vibration and noise
• Drivetrain Stability: Maintains correct engine position during driving loads
• Component Protection: Helps reduce stress on exhaust, transmission and drivetrain components
Engine mounts are exposed to constant heat, vibration and load from the engine. Over time the hydraulic fluid and rubber components may deteriorate, reducing their ability to damp vibration. This can lead to increased engine movement, cabin vibration or knocking during acceleration and gear changes. Replacing worn mounts with OE Match units restores smooth engine operation and protects drivetrain components from excessive stress.
Consider replacing the engine mount if you notice:
• Increased vibration inside the cabin
• Clunking or movement during acceleration or gear shifts
• Engine movement when revving the engine
• Visible cracking, leakage or collapse of the mount

The Mount for the Porsche 997 Generation 1 and Generation 2 Coupe (Porsche product code 99737504908) serves as a critical component that secures the engine to the vehicle's chassis. It helps to absorb vibrations and impacts from the engine during operation, maintaining stability and ensuring a smooth ride. This particular engine mount is designed to meet the specific structural and performance requirements of the Porsche 997, providing durability and reliability for both everyday driving and performance enhancements. Proper functioning of the engine mount is essential for optimal engine performance and to minimize wear on other related components.
• Position on Vehicle: Front engine mount assembly (left OR right side) – front of the engine block, attaching to the chassis via mount bracket.
• Cross-Reference / Alternative Numbers: OEM: 997 375 049 08; also superseded from 997 375 049 04 and 997 375 049 06 in earlier listings.
• Applications: Use this mount when original mount shows signs of failure — to restore engine stability, reduce vibration, maintain correct engine alignment and safeguard ancillary components.
An engine mount plays a vital role in stabilising the powertrain and isolating engine-borne vibration from the cabin and chassis. Over time the hydraulic fluid, rubber bushings or bonding will degrade, causing increased engine movement, vibration, noise or premature wear of transmission and drivetrain components. Replacing a suspect mount restores comfort, handling precision and engine/gearbox alignment.
When and why to replace:
• Noticeable engine vibration, rumble or harshness in the cabin or at idle.
• Visual signs of mount wear: cracked rubber, leaking fluid, broken bracket.
• After engine removal, major service or performance upgrades (making access easier).
• High-mileage vehicle where original mounts are likely ageing and losing damping capability.
• Preventive replacement before mount failure protects drivetrain components and avoids costly collateral damage.

OEMatch Engine Mounts — Durability, Sealing, Performance
Engine mounts secure the engine to the chassis while damping vibration and maintaining drivetrain alignment. For Porsche models, OEMatch Engine Mounts are selected to restore stability and reduce transmitted vibration, helping to preserve handling precision and protect connected components during everyday and spirited use.
Available Types
- High-grade rubber engine mounts
- Performance polyurethane mounts
- Reinforced composite mounts
- Hydraulic or fluid-filled mounts where specified by model
Understanding OEMatch Engine Mounts
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original engine mounts.
OE (Original Equipment) refers to parts matching original specifications for the engine mounts and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM engine mounts engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Engine mounts hold the engine and transmission in the correct position while isolating vibration from the cabin and drivetrain. Different constructions balance isolation and control: rubber absorbs vibration, polyurethane can offer firmer control, and reinforced composites aim to combine strength with damping. OEMatch focuses on engine-mount items selected for Porsche applications to support correct fit and function.
Benefits Include
- Restores drivetrain stability and precise engine positioning
- Reduces vibration and harshness for improved cabin comfort
- Protects hoses, wiring and exhaust connections from excess movement
Why Engine Mounts Wear and Fail
- Material fatigue from repeated heat cycling and age
- Oil or fluid contamination that softens rubber or polymer parts
- Excessive engine torque or vibration, especially on modified or high-mileage engines
- Corrosion or cracking in metal brackets and mounting hardware
The Importance of Replacing with OEMatch Engine Mounts
Replacing worn engine mounts maintains accurate engine positioning and reduces secondary stresses that can accelerate wear on hoses, wiring, exhaust connections and transmission mounts. Timely renewal helps preserve the handling balance and refinement expected from a Porsche and avoids secondary repairs caused by excessive engine movement.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances
- Made to original-spec dimensions for consistent performance
- Compatible with factory systems and sensors where required by model
