Performance intercooler upgrade kit.
To Fit:
Porsche 911 997.1 Turbo 2007-2009 and GT2RS models
Porsche 911 997.2 GT2 RS model 2010 to 2012
Porsche 911 997.2 Turbo 2010 to 2012
A true performance upgrade intercooler kit for the 997.1 Turbo and GT2. This well thought out refined kit allows fitment of the larger later type 997.2 intercoolers onto the 997.1 model, and includes all the components and hardware necessary for a serious upgrade!
Significant advantages with Do88's Porsche Performance Intercooler Kit:
• Cooler air to your engine!
• High quality, high density UK made motorsport cores.
• 3D freeform designed cast end tanks.
• Custom designed carbon fibre ambient air guides.
• Comes with high quality silicone hoses and accessories for installation.
• See enlarged images for more information!
Do88: After our market research in the beginning of our intercooler development for the 997 generation 2 we understood that not many of the upgrade products on the market are really upgrades but more at the same level as the 997.2 standard intercoolers or sometimes even lower. For this reason we realised from the beginning we could not sacrifice anything to keep the cost down, we just had to do the best possible in the space available in the car!
First of all we carried out a lot of investigation and comparisons between different core types and at last really fell for a high density motorsport core which has great cooling efficiency as well as being light weight. With a great core in place we started to refine the end tank design which brought us to a decision to make cast end tanks as we could then control the air flow distribution over the core in a very precise way. This is very important as a good tank design will be beneficial for both pressure drop and cooling efficiency.
To be able to fit an intercooler with appropriate thickness for the job it was also necessary to design a new upper ambient air guide. This was designed in our 3D scanned environment from carbon fibre to ensure perfect fit to the vehicle integrated air guides and our intercooler. To achieve the best air flow distribution over the core we made intercooler end tanks with 70 mm (2 3/4 inch) connections which then made it necessary to designed custom silicone hoses for all positions.
The hoses are 3D designed with airflow in mind where we CFD tested each hose during development to ensure best possible flow rate of all parts! The hoses between turbocharger and intercooler are special silicone hoses that can withstand up to 240°C (464°F) continuous temperature! Another important aspect for cooling performance is to maximise all ambient cooling air available, to optimise this part we include air block rubber seals for all surfaces where the ambient air guides must seal properly.
With the way we have chosen to build our intercoolers the weight increase compared to the OEM ones is relatively small considering the size of our intercooler and that it's completely made of aluminium. Our intercooler weight is 5,85 kg (12,89 lb) per piece and the 997.2 OEM intercooler weights 3,30 kg (7,27 lb) per piece. It might sound like a big weight increase but not when you compare it to similar core sized intercoolers on the market!
Included in this kit:
• Performance intercoolers
• Carbon fibre air guides
• Silicone hoses
• Hose clamps
• Rubber seals
• Installation hardware
When it comes to performance our intercooler kit gives a great reduction of the intake temperature compared to the OEM 997.2 intercoolers! See enlarged diagrams where we show data from our AIM racelogger recorded at 5 full throttle accelerations done in an immediate sequence without any cool down between 40-260 km/h (25-162 mph) in a Stage 1 tuned Porsche 997.2 Turbo PDK. In all tests the car was driven in Sport Plus, automatic gear change and AC off. First we made 5 runs with the car equipped with OEM intercooler and y-pipe then we switched to do88 performance intercoolers and y-pipe and drove car for a while, then we made 5 runs exactly the same as with the OEM parts. The temperatures are significant lower with our intercoolers which is visible in the graph!
As well as lower intake temperature our big pack also flows better than the 997.2 original intercoolers! See enlarged image showing the air flow rates at different pressure drops in the graph where we compared our big pack to the original intercooler and Y-pipe in our own Superflow SF-1020 Probench to verify the final result!
From our five in a row full throttle accelerations between 40-260 km/h (25-162 mph) we have very accurate and consistent test data for the range 50-250 km/h (31-155 mph). When analyzing the numbers, we found that in average we cut down the acceleration time for 50-250 km/h (31-155 mph) by 3 seconds compared to the OEM intercooler and y-pipe! No software programming or adaption reset was done in between the tests.

Information
Charge air cooler by Mahle for Porsche 957 and 958 Cayenne 3.0L Diesel models. It forms part of the turbocharged engine's charge-air cooling system, helping to reduce the temperature of compressed intake air before it enters the engine.
Fits

- Cayenne 958 V6 3.0L Diesel (245Hp) 2010–17
What This Product Does
The charge air cooler transfers heat away from compressed intake air. Maintaining a sealed, undamaged cooler and associated pipework supports consistent charge-air flow through the intake system.
Functions
- Cools compressed intake air within the charge-air system.
- Provides a connection point for the relevant pressure hoses and pipes.
- Helps maintain a sealed route for turbocharged intake air.
Technical Details
- Charge air cooler reference 958145803A: left-hand side.
- Charge air cooler reference 958145804A: right-hand side.
- Shown for Cayenne 9PA1 (957) 3.0L Diesel 2007-10.
- Also shown for Cayenne 92A (958) 3.0L Diesel applications, including 2011-18 and 05/2014-18 diagram coverage.
- Related assembly components include pressure hoses, seal rings, hose clamps, retaining springs and pressure pipes.
Symptoms of Fault
- Hissing from the charge-air system.
- Loss of boost or reduced engine response under load.
- Underboost-related fault messages.
- Oil residue around the cooler connections or pipework.
- Visible damage, corrosion or distorted cooling fins.
Why Replacement Matters
A leaking or damaged charge air cooler can allow boosted air to escape and may affect intake-air temperature control. Replacing a faulty unit while checking its seals, hoses, clamps and retaining hardware helps address the complete charge-air connection.
FAQs
- Is this cooler side-specific?
Yes. Diagram reference 958145803A is left-hand, while 958145804A is right-hand. - Should related parts be inspected during replacement?
Inspect the pressure hoses, seal rings, clamps and retaining hardware for wear or damage. - How can a charge-air leak be confirmed?
A suitable pressure test of the charge-air system can help identify leaks in the cooler, hoses and connections.
Check fitment for your specific vehicle, including model, year and engine, before ordering.

Front radiator intercooler
This OE Match intercooler is a direct replacement for Porsche part, manufactured to original specifications, it ensures precise fitment and reliable performance within the turbocharged intake system. Installed at the front of the vehicle, the intercooler cools compressed air from the turbochargers before it enters the engine. By reducing intake air temperature, it improves combustion efficiency and supports optimal engine performance.
Fits:
Porsche 957 Cayenne Turbo 4.8L 2007 - 2010
Porsche 958 Cayenne Turbo 4.8L 2011 - 2018
Diagram ref no 1 (left) and 2 (right)
The intercooler lowers the temperature of compressed air from the turbochargers, increasing air density and improving engine efficiency. This results in better power output, improved throttle response, and enhanced reliability.
A properly functioning intercooler is essential for maintaining consistent turbo performance and preventing heat-related power loss.
Function
• Cools compressed intake air from turbochargers
• Improves combustion efficiency and engine performance
• Maintains stable intake air temperatures
• Supports consistent boost pressure and power delivery
This component is critical for performance and engine protection in turbocharged vehicles.
Over time, intercoolers can become clogged, corroded, or develop internal leaks, reducing their cooling efficiency. This can lead to higher intake temperatures, reduced performance, and increased engine stress.
Replacing a worn intercooler restores proper cooling, improves engine efficiency, and ensures reliable turbocharged performance.
When to replace:
• Loss of power or reduced turbo efficiency
• Boost leaks or hissing noises
• Oil contamination inside intercooler
• Visible external damage or corrosion
• Fault codes related to intake temperature or boost pressure
