When you need a replacement or upgrade spoiler for your Porsche, specific part numbers like 981-505-557-02-10 are essential. This particular part corresponds to a sport spoiler designed for the Porsche 981 chassis, which includes the Boxster and Cayman models from 2013 to 2016. Whether your original spoiler was damaged, or you want to add a sportier look, understanding this part ensures you get the right fit and function.
Overview of Porsche Part Number 981-505-557-02-10
The part number 981-505-557-02-10 is a genuine Porsche sport spoiler. It is commonly referred to as the “SportDesign” or “Aerokit” rear spoiler. This component is a factory accessory that enhances both aesthetics and aerodynamics. The “10” in the part number likely denotes the color or finish—often black or primed for painting. However, it is crucial to verify with your dealer because Porsche uses a suffix to indicate the final paint code or primer stage.
What Models Does It Fit?
This spoiler is specifically designed for the 981 generation:
- Porsche Boxster (981) – 2013 to 2016
- Porsche Cayman (981) – 2014 to 2016
It fits both Coupe and Convertible variants, but not the Spyder or GT4 models, which have different rear end designs. The spoiler replaces the standard pop-up spoiler with a fixed sportier unit. It mounts using the existing holes and wiring for the pop-up mechanism, but note that you may need to disable the automatic function or remove the actuator if you switch to a fixed spoiler.
Compatibility and Fitment Details
Before purchasing, confirm that your car has the standard pop-up spoiler (most 981 models do). The part number 981-505-557-02-10 is a direct replacement for the factory retractable spoiler. It uses the same bolt pattern and requires no additional drilling. However, keep in mind:
- Active Spoiler Feature: This part is fixed. Once installed, your car will not have a movable spoiler. Some owners choose to keep the mechanism functional by wiring it to a switch, but that is not plug-and-play.
- Paint: The spoiler typically comes primed in a dark gray or black primer. You will need to have it painted to match your vehicle’s color. Professional paint work is recommended for a flawless finish.
- With or Without Third Brake Light: The 981-505-557-02-10 includes the integrated third brake light (LED). Ensure your car’s wiring harness can connect to it. Most 981 models are pre-wired.
Installation Considerations
Installing this sport spoiler is a moderate DIY job if you have mechanical skills, but many owners prefer professional installation to avoid damage to the paint or body panels.
Tools and Steps
- Remove the original pop-up spoiler. This involves unbolting it from the decklid and disconnecting the electrical connector.
- Disable or remove the lifting mechanism if you do not want it to activate. You can simply unplug the module or remove the actuator (consult a wiring diagram).
- Test fit the new spoiler—ensure it sits flush against the decklid.
- Apply the provided adhesive foam tape (if included) or use automotive-grade double-sided tape for extra security.
- Bolt the spoiler in place. Torque the nuts to factory specifications (typically around 8 Nm).
- Connect the brake light wiring. Secure the wires to avoid rattling.
- Do a final check for any gaps or misalignment.
Professional vs DIY
If you are not experienced with automotive body panels, consider hiring a Porsche specialist. They will ensure proper alignment and seal to prevent water leaks. The spoiler is exposed to the elements, so correct installation matters.
OEM vs Aftermarket Alternatives
Genuine Porsche parts, like the 981-505-557-02-10, offer the best fit and materials. They are made of high-quality ABS plastic that matches the original part’s texture and durability.
Aftermarket Options
There are several aftermarket replicas of the SportDesign spoiler. They are cheaper (often $200–$400 vs $600–$800 for OEM) but come with risks:
- Material quality: Some aftermarket parts use lower-grade plastic that can warp or fade in sunlight.
- Fitment issues: Gaps may be larger, requiring additional bodywork to look seamless.
- Brake light integration: Aftermarket spoilers may not include the LED light or may have incompatible connectors.
If you prioritize cost, aftermarket could be acceptable, but be prepared to spend on paint and possibly modifications. For a perfect, worry-free fit, OEM is recommended. The part number 981-505-557-02-10 is available from Porsche dealerships and authorized online parts retailers.
Where to Buy the Porsche 981-505-557-02-10 Spoiler
Since this is a genuine Porsche part, you can order it from:
- Porsche Dealership Parts Departments: They can confirm fitment and will order the part from the factory. Expect a wait time if not in stock.
- Authorized Porsche Parts Retailers: Websites like Suncoast Parts or Pelican Parts sell OEM parts. They often have competitive pricing and fast shipping.
- Online Porsche Forums: Members occasionally sell new or used OEM spoilers. Ensure the part number matches exactly.
Verify the part number includes the correct suffix for your desired finish. Some retailers list the part with a color code. If you need the spoiler painted, order the primed version and pay a bodyshop.
Practical Recommendation
For most owners, the genuine Porsche SportDesign spoiler (981-505-557-02-10) is the best choice. It gives your 981 Boxster or Cayman a more aggressive look while maintaining OEM quality. The added downforce at high speeds is minimal but noticeable on track days.
Before buying:
- Check your VIN with a dealership to confirm compatibility.
- Decide whether you want a fixed spoiler or prefer to keep the pop-up function. This part is fixed.
- Budget for painting and installation if you cannot do it yourself.
If you are on a tight budget, a reputable aftermarket spoiler might suffice, but be aware of potential fitment problems. For a seamless upgrade that holds value, stick with the genuine Porsche part.
In summary, the part number 981-505-557-02-10 is your ticket to a sportier rear end. With proper installation and paint, it will look factory-installed and provide years of service. Whether you are restoring a damaged spoiler or upgrading your Porsche’s appearance, this is a solid choice.
