Product Information

Rear Spoiler Water Deflector, Black.

The Rear Spoiler Water Deflector (Black) is a genuine OEM Porsche component set designed for the active rear spoiler assembly on Porsche 911 (997 generation) models. These deflectors are installed along the rear spoiler/engine lid area to help guide rainwater and runoff away from key trim sections and spoiler mechanism components.

Fits:

Porsche 997 MKII Carrera C2 3.6L 2009-12
Porsche 997 MKII Carrera C4 3.6L 2009-12

By reducing unwanted water pooling and directing moisture away from sensitive areas, the deflectors help maintain a cleaner rear spoiler assembly and support long-term condition of surrounding fittings and bodywork. Finished in factory-correct black, they also restore the original OEM appearance and ensure the spoiler area looks complete and properly finished.

Ideal for replacing damaged, cracked, missing, or warped deflectors—especially after accident repairs, spoiler servicing, or normal wear—these parts provide a direct-fit solution manufactured to Porsche factory specifications for correct alignment and fitment.

What This Product Does:

Helps deflect rainwater and runoff away from the spoiler mechanism area
Reduces water pooling around rear spoiler trim and joints
Maintains clean airflow and correct finishing around the active spoiler
Helps protect surrounding components from moisture and dirt build-up
Restores OEM fit and appearance of the rear spoiler area

Symptoms Of A Worn Or Missing Water Deflector:

Missing spoiler deflector trim after repairs
Cracked, warped, or broken plastic sections
Loose or poor-fitting trim around the spoiler area
Water pooling where it shouldn’t on the rear lid/spoiler edges
Increased dirt and debris build-up around spoiler joints

Why Replacement Matters:

Maintain a tidy, sealed factory finish around the spoiler
Reduce moisture exposure near spoiler mechanism and fittings
Prevent loose trim, rattles, or poor fitment
Support long-term condition of rear spoiler and lid components
Keep the vehicle’s rear end looking correct and complete

Rear Engine Lid Damper. Porsche 997.1 GT3 RS / 997.2 GT2

99751255191

Product Information

Rear Engine Lid Damper
The Porsche Genuine OE Rear Engine Lid Damper (Part No. 99751255191) is an original factory gas-filled support strut / gas pressure damper designed for the rear engine lid assembly on high-performance Porsche 997 GT models.
1 required per vehicle

Fits:
Porsche 997.1 GT3 RS 2007 - 2013 (PR:004)
Porsche 997.2 GT2 2010 - 2013

Diagram ref no 4

The rear engine lid damper assists with lifting and supporting the engine cover while keeping it securely open during servicing or inspection.

The gas-filled design counterbalances the weight of the GT rear lid and spoiler assembly, ensuring controlled opening and preventing the lid from dropping unexpectedly. This is especially important on GT and RS models fitted with larger aerodynamic rear wings.

Functions & Technical Role
•  Engine lid support: Assists lifting and holding the rear lid open
•  Gas pressure operation: Provides smooth and controlled movement
•  GT spoiler support: Designed for heavier GT and RS rear deck lids
•  Service accessibility: Improves safe access to the engine compartment
•  OEM precision: Manufactured to Porsche factory specifications for exact fitment and durability

Fitment / Position on Car
• Fitting position: Rear
• Location: Rear engine lid / rear deck lid assembly
• System: Rear lid lifting and support mechanism
• Typically fitted: Between the chassis mounting point and engine lid hinge assembly

The rear engine lid damper supports the heavy GT rear spoiler assembly and prevents sudden closing of the engine lid. A weak or failed damper can make the lid difficult to open and unsafe to hold in position.

When to Replace:
• Rear lid no longer stays open
• Weak or uneven lifting force
• Oil leakage from the gas strut
• Difficulty opening the engine cover
• During rear lid or spoiler restoration work

Rear Engine Lid Damper. Porsche 997 GT3

99751255191/1

Product Information

Rear Engine Lid Damper.
The OE Match Rear Engine Lid Damper is a premium-quality replacement gas strut designed to provide smooth, controlled opening and secure support of the rear engine lid on compatible Porsche models. Manufactured to OE specifications for fit, lifting force and durability, this gas damper restores the original operation of the engine lid, ensuring safe and convenient access to the engine compartment.

Fits:

Porsche 997 MK1 GT3 / GT3 RS 2007-09
Porsche 997 MKII GT2 RS 2011-13

Filled with high-pressure nitrogen gas and incorporating precision hydraulic damping, the strut delivers consistent lifting assistance and controlled closing action. Manufactured from high-strength steel with a corrosion-resistant finish, premium seals and a precision-ground piston rod, it is designed to withstand frequent operation, engine bay temperatures and long-term exposure to the elements.

What This Product Does:

Supports the weight of the rear engine lid.
Provides smooth, controlled opening and closing.
Holds the engine lid securely in the open position.
Reduces strain on the hinges and mounting brackets.
Prevents the engine lid from dropping unexpectedly.
Improves safety during engine maintenance.
Restores factory-style lifting performance.
Forms an essential part of the rear engine lid support system.

Symptoms Of Wear Or Failure:

Engine lid failing to remain open.
Engine lid dropping unexpectedly.
Weak or reduced lifting assistance.
Jerky or uneven opening movement.
Oil leakage from the gas strut.
Corrosion or damage to the piston rod.
Excessive effort required to raise the engine lid.
Squeaking or knocking noises during operation.
Loose or worn mounting points.
Complete loss of gas pressure.

Why Replacement Matters:

The rear engine lid damper is subjected to repeated opening and closing cycles, engine heat, vibration and changing weather conditions. Over time, the internal gas charge gradually diminishes while the seals and damping mechanism wear, reducing the strut's ability to support the engine lid correctly.
A weakened damper can allow the engine lid to close unexpectedly, creating a potential safety hazard and increasing stress on the hinges and latch assembly. It can also make routine maintenance more difficult by requiring the lid to be manually supported.
Replacing a worn rear engine lid damper restores smooth, controlled operation and ensures the engine lid remains securely open when required. The OE Match replacement provides factory-style fitment, dependable lifting performance and long-lasting durability, helping maintain the convenience, safety and reliability expected from your Porsche.
