Product Details

Genuine Porsche Power Steering Plus Activation – Speed-Sensitive Steering Upgrade Fits 2013–2026 Porsche Boxster & 718 Boxster | 2014–2026 Cayman & 718 Cayman | 2013–2019 911 Carrera (Standard Power Steering Models)

Porsche's Power Steering Plus is one of those features that fundamentally changes the way your car communicates with you — and if your Porsche left the factory without it, this software activation adds it exactly as Porsche intended, with no hardware modifications and no aftermarket compromise.

Power Steering Plus is a speed-sensitive system that adapts continuously to your driving situation. At highway speeds it firms up and sharpens, delivering the precise, connected feel that Porsche sports cars are known for. At low speeds — maneuvering through traffic, parking, tight corners — the steering ratio adjusts for effortless, comfortable control. It's the best of both worlds, and it's pure Porsche engineering.

What's Included

  • Software license — VIN-specific coding submitted directly to Porsche, uploaded by your installing dealer from the Porsche network
  • No hardware or physical products are shipped — this is a pure software activation
  • Dealer installation guide for authorized Porsche technician installation

What Power Steering Plus Does For Your Porsche

At High Speed The steering firms up and responds with greater precision — more weight, more feel, more connection between your hands and the road. Exactly what a Porsche sports car should feel like at speed.

At Low Speed The steering ratio adjusts automatically for easy maneuvering and parking — lighter, more responsive, and effortless in tight situations without sacrificing the feedback that makes these cars so rewarding to drive.

The Result A steering system that feels alive in every situation — adapting seamlessly between comfort and precision without any driver input required. Set it and forget it, knowing your Porsche is always delivering the right feel for the moment.

Critical Information — Please Read Before Ordering

This activation is VIN-specific and coded exclusively for your car. Please take note of the following before placing your order:

  • ⚠️ Your VIN must be 100% accurate — an incorrect VIN means the software will not work and the activation cannot be used
  • ⚠️ This activation is non-returnable under any circumstance — please contact us with any questions before ordering
  • Professional installation required by an authorized Porsche dealer — your dealer retrieves and uploads the coding directly from the Porsche network
  • No physical product will be shipped — please order only when you are ready to proceed with dealer installation.  Only comes with an installation guide, the rest is done through Porsche.

Why Upgrade? Steering feel is one of the most intimate aspects of the driving experience — it's how your Porsche talks to you, and how you talk back to it. Power Steering Plus makes that conversation richer, more nuanced, and more rewarding in every driving situation. For Boxster, Cayman, and 911 owners who didn't option it from the factory, this is a rare opportunity to add a feature that genuinely transforms the day-to-day driving experience.

This isn't an aftermarket modification. This isn't a workaround. This is Genuine Porsche software, the exact same system fitted to Power Steering Plus equipped cars at the factory — activated by your local Porsche dealer, specific to your VIN, and backed by Porsche's own engineering.

One activation. A lifetime of better steering.

PSP is a must do mod
5 out of 5 stars.
Kevin Duong (Arizona) | December 24th, 2025
Only have Power Steering Plus software installed by North Scottsdale Porsche on my 2015 911 S for 3 days but already makes me think this is the best mod I’ve done. PSP makes trip s to local grocery stores, shopping center, coffee shops or any other tight spot slow speed driving so enjoyable. Yesterday when I installed TLG mud guards, standing outside of vehicle I actually just used two fingers to turn the steering wheel all the way to one side so I could install the mud guards. Low speed driving is so easy and relaxing . Highly recommend this especially for 991.1.

Porsche Parts Warranty Information — Suncoast Porsche

Understanding your warranty coverage is important. Below is a complete overview of warranty terms for Genuine Porsche OEM parts, aftermarket parts, and closeout items purchased from Suncoast Porsche and SuncoastParts.com.

Warranty Coverage by Product Type

Genuine Porsche OEM Parts — 2-Year Warranty

All Genuine Porsche OEM parts purchased from Suncoast Porsche or SuncoastParts.com come with a 2-year, unlimited mileage, parts-only warranty beginning on the date of purchase.

If your parts are installed at an authorized Porsche Service Center, both parts and labor warranty coverage may apply if the part is deemed defective within the 2-year warranty period. Coverage varies by location — please check with your local Porsche dealer prior to installation to confirm their specific warranty participation, as each Porsche Center is independently owned and operated.

Important warranty notes for online purchases:

  • Labor, diagnostic, and installation fees are not covered when parts are purchased online from SuncoastParts.com or Suncoast Porsche, unless the parts are installed by an authorized Porsche Service Center
  • Warranty claims must be processed in person at an authorized Porsche Service Center
  • Warranty service is honored at any authorized Porsche dealer in the United States, however some dealers may decline warranty claims for parts purchased online or from another dealership — always verify with your local dealer before installation
  • If a warranty claim is approved and the part was not installed by a Porsche Service Center, installation of the replacement part remains the customer's responsibility
  • Suncoast Porsche and SuncoastParts.com are not liable for any diagnostic, labor, or installation fees charged by another Porsche Service Center

Aftermarket & Performance Parts

Warranty coverage for aftermarket and performance parts varies by manufacturer. Most carry a 1-year limited warranty. Contact us for specific warranty details on any aftermarket product. Please note that diagnostic time and labor costs for warranty replacements are not covered.

Take-Off & Closeout Parts

All take-off and closeout parts are sold as-is with no warranty and are not eligible for return. Pricing on these items reflects their as-is condition.

What This Warranty Does Not Cover

The following situations and conditions are explicitly excluded from warranty coverage:

  • Improper Installation or Misuse — Damage resulting from incorrect installation, negligence, unauthorized alteration, or accident. This includes any use in racing, competition, or motorsport applications
  • Lack of Proper Maintenance — Damage caused by failure to follow the vehicle's recommended Maintenance Schedule, or failure to use the correct fluids, fuel, oil, or lubricants as specified in the Owner's Manual. Proof of proper maintenance is the owner's responsibility — retain all service receipts in case questions arise
  • Consequential or Economic Losses — Towing fees, rental vehicles, loss of use, loss of time, inconvenience, or any other indirect economic losses
  • Vehicles Outside the USA & Canada — Parts installed on vehicles registered or primarily operated outside of the United States or Canada are not covered under this warranty

How to Obtain Warranty Service

Installed by an Authorized Porsche Dealer

If your parts were originally installed by an authorized Porsche dealer, warranty repairs may be performed by that same dealer or any other authorized Porsche Service Center in the United States. Please allow a reasonable timeframe for repairs after delivering your vehicle to the dealership.

Installed by an Independent Repair Shop

Please be aware: All warranty claims must be inspected, performed, and documented by factory-trained Porsche technicians at an authorized Porsche dealership. Work performed at an independent repair shop does not qualify for warranty consideration. If warranty coverage is a priority, we strongly recommend having your parts installed at an authorized Porsche Service Center.

Documentation Requirements for Warranty Claims

To process a warranty claim, the servicing Porsche dealer will require:

  • Your original sales receipt or order confirmation from SuncoastParts.com or Suncoast Porsche
  • A completed warranty certificate
  • Proof of proper vehicle maintenance history (if applicable)

Suncoast Porsche retains sales records on file for two years. If you need a copy of your receipt, contact us and we will provide it promptly.

This warranty provides you with specific legal rights. You may also have additional rights that vary by state.

Porsche does not authorize any individual or organization to create additional obligations or liabilities beyond those stated in this warranty. Any implied warranty of merchantability or fitness for a particular purpose is limited in duration to the term of this written warranty. The exclusive remedy under this warranty is the repair or replacement of the defective part.

Suncoast Porsche and SuncoastParts.com shall not be liable for any incidental or consequential damages arising from a breach of this written warranty or any implied warranty.

Some states do not permit limitations on implied warranty duration or the exclusion of incidental or consequential damages — the above limitations may not apply in your state. Additionally, installation of certain parts or accessories may affect your Porsche New Vehicle Warranty. Please consult your authorized Porsche dealer for full terms, or contact us with any questions.
