Genuine Porsche Third Center Radiator Upgrade Kit – Enhanced Cooling for Track & Performance Fits 2005–2008 Porsche Boxster | Boxster S | 2006–2008 Cayman | Cayman S | Manual Transmission Only (987.1 Generation)


When Porsche builds cars destined for hot climates and desert regions, they add a third center radiator to the front bumper — a factory solution to the demands of extreme heat and hard driving. We are the only company offering this upgrade as a complete, ready-to-install package using 100% Genuine Porsche factory parts, and everything plugs directly into place exactly as Porsche intended.

If you're pushing your 987.1 Boxster or Cayman on track, running performance upgrades, or simply want the peace of mind that comes with maximum cooling capacity, this is the upgrade your car was engineered to accept.

What's Included

  • Genuine Porsche center radiator
  • All necessary hardware for a complete installation
  • 100% factory Porsche parts throughout — no aftermarket components
  • Coolant is not included — please see our related items below for the correct coolant specification

What This Upgrade Does The standard two-radiator setup handles everyday driving with ease. Add back-to-back track sessions, performance modifications, or consistently high ambient temperatures, and the thermal margin narrows quickly. The third center radiator gives the engine more headroom exactly when it matters most — helping maintain consistent performance lap after lap, on the street or on track.

An Important Note This is not a factory recommended upgrade for standard 987.1 models sold in temperate climates — Porsche fits this third radiator selectively to vehicles destined for hot climate markets. However, it has become a well-established and widely popular upgrade among Boxster and Cayman enthusiasts, track day drivers, and performance-focused owners who want the added thermal confidence that comes with a complete factory cooling system. Every part in this kit is a Genuine Porsche component — this is simply putting those parts to work on your car.

Fitment

  • Fits: 2005–2008 Porsche Boxster | Boxster S (987.1 generation)
  • Fits: 2006–2008 Porsche Cayman | Cayman S (987.1 generation)
  • Manual transmission only — this kit is specifically designed for manual transmission equipped cars
  • Tiptronic equipped cars do not require this upgrade — if your 987.1 has the Tiptronic transmission, this kit is not necessary for your vehicle

Model-Specific Fitment Notes Please read carefully before ordering — fitment requirements vary slightly between models:

  • Boxster S & Cayman | Cayman S — ports must be cut into the bottom of the front bumper to allow proper airflow to the center radiator
  • Boxster (base model) — in addition to bumper port cutting, a center duct must be cut into the bumper and a small trim opening will require painting for a finished appearance. We strongly recommend professional installation for the base Boxster to ensure a clean, factory-correct result

Installation Notes Professional installation is highly recommended for this upgrade. Please note the following:

  • Ports must be cut into the bottom of the front bumper on all models — this is a permanent modification and must be performed cleanly and precisely
  • Base Boxster models require additional bumper work and painting of a small trim opening — see model-specific notes above
  • Dealer-level programming is required to properly bleed and "burp" the cooling system after installation
  • Coolant is not included — please see our related items below for the correct coolant for your 987.1

Why Upgrade? On track, cooling is performance. Every degree of thermal headroom you add is another degree of confidence that your 987.1 Boxster or Cayman is operating at its best when you're pushing hardest — lap after lap, session after session. Porsche engineered this exact solution for their most demanding operating environments, and we've made it available as a complete factory-correct package for your 987.1.

This isn't an aftermarket intercooler or a modified cooling solution. This is the exact system Porsche installs on factory builds requiring maximum thermal management — every part, every hose, every duct, straight from Porsche.

Built for the track. Engineered by Porsche. Available only here.

Affordable, factory engineered upgrade for your first gen Cayman.
5 out of 5 stars.
Chris (Utah) | August 30th, 2021
This Suncoast kit included everything needed to add the third radiator, with all Porsche made parts. It's worth looking up the front bumper removal on YouTube if you haven't done it before, but nothing too complicated. You only need a metric set of sockets (I think 10mm, 13mm and 16mm covers it) 25 and 30 torx head bits, and a screw driver to help with clips. This added cooling, plus a deep sump oil pan kit, should keep your first gen M97 engine comfortable for the more spirited drives. Cheap insurance.
Simple easy upgrade all in one nice kit
5 out of 5 stars.
Rick (Pennsylvania) | May 26th, 2020
Adding the center radiator to my 987.1 was incredibly easy with this kit, very complete, all factory parts fit like a glove. One of the easiest upgrades I have done on an automobile from any kit. Price is right as well!
Easy to install and a great decision.
5 out of 5 stars.
Bob (Alabama) | April 3rd, 2020
I ordered this part to help with the cooling of my v8 987.1 Cayman S. The parts included were a perfect fit and installation is self explanatory once you pull the parts out of the box. The longest part of the install was removing the bumper. The hoses connect quickly and can be done without losing more than a cup of coolant all together. The extra cooling capacity helped a lot and I’d definitely recommend this product.
Super easy
4 out of 5 stars.

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.
