A true performance cooling upgrade for the 991 Turbo / Turbo S
This is the most refined of all products we carry today!
• Significantly improved Air flow! (see graph images).
• Cooler air to your engine!
• High quality high density UK made motorsport cores.
• 3D freeform designed cast end tanks
• Custom designed carbon fiber ambient air guides.
• Comes with high quality silicone hoses and accessories for installation.
About the intercoolers: Right from the beginning we realised that 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 made a lot of investigation and comparisons between different core types and at last really fell for a high density motorsport core which have great cooling efficiency along with a low 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 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 design 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 are to use all ambient cooling air available, to optimize this part we include air block rubber seals for all surfaces where the ambient air guides must seal properly.
Using this design in building our intercoolers the weight increase compared to the OEM ones is relatively small considering the size of our intercooler and that its all made of aluminium. Our intercooler weight is 5,4 kg (11,9 lb) per piece and the 991 OEM intercooler weights 3,1 kg (6,8 lb) per piece. It might sound like a big weight increase but compared to other actors on the market with intercoolers in this size it's a low weight!
At the same time as our intercoolers lower the intake temperature, they also flow better than the 991 original intercoolers! Please have a look at the air flow rates at different pressure drops in the graph below where we compared our intercooler with hoses to the original intercooler with hoses in our own Superflow SF-1020 Probench to verify the final result!
Keep in mind that the OEM intercoolers was designed for only the power level the car was built for originally. A power increase may cause your stock intercoolers to not be efficient enough. So even on an engine with a software tune only or using your car in hot climate the do88 performance intercooler kit will give a performance increase over the OEM intercoolers!
This do88 performance intercooler kit comes as a complete package with all parts necessary for installation.
Please Note! Some modifications need to be done when installing this intercooler kit, please read step 29,31 & 35 in the installation guide before placing order.
Installation Instruction
About the Y Pipe
Our pipe has both a very good flow rate and a low weight which is accommodated by composing mandrel bent lightweight pipes with a high quality 3D freeform designed cast joint between them. Onto the cast part we then weld CNC-machined connections for bov and breather hoses. This construction technique adds a lot of performance but only a touch of extra weight. The pipes are then finished in a high quality powder coat that makes them look as good as they perform!
When it comes to air flow performance our Y-pipe totally outperforms the OEM Y-pipe by 58% increased flow at the same pressure drop! Be aware of that the OEM parts are only designed for the power level the car was built for originally. A power increase may cause your stock Y pipe to hold back the power of your engine. So even on an engine with a software tune only the do88 performance Y-pipe will give a performance increase over the OEM Y-pipe!
Much larger inner diameter for improved air flow, 58 % higher! (see graph images).
Made of 2,5" (63mm) mandrel bent aluminium pipes.
The pipe has two methanol injection connections (1/8 -27 NPT). The pipe is delivered with blanking plugs in these connections.
Smooth flow cast collector part.
Smooth internal surface for best air flow.
Comes with high quality silicone hoses and accessories for installation.
About the Inlet Hoses
do88 proudly presents the worlds first high flowing turbo inlet hoses for Porsche 991.1 / 991.2 Turbo. Self developed by do88 in Sweden !
• Much larger overall inner diameter for improved air flow, 31 % higher! (see graph diagram ). The hoses have a 2,5 inch (63mm) inner diameter at the narrowest location.
• Smooth flow transitions.
• Very smooth internal surface for best air flow.
• Excellent thermal properties, the hoses will not absorb heat from the engine.
• The hoses are reinforced with stainless steel wire to eliminate the risk of implosion on high out-takes.
It was a real challenge developing new turbo intake hoses for the 991 Turbo. The lack of space made it really difficult to make a set of hoses that would outflow the stock plastic pipes. We succeeded but in some smaller areas we had to compromise and allow these hoses to have no clearance, so they will push or rub in some non-sensitive areas.
We can ensure you the sensation while driving is very different. The improvement in throttle response is immense, making the car feel so much more refined and alert. This upgrade makes it become what it should have been from the start. This is an improvement no test figures can explain, it has to be perceived behind the wheel of a 991 turbo!
The inlet hose package includes everything for mounting:
• 2 wire-reinforced silicone hoses
• 2 silicone hoses
• 2 breather valves
• 2 CNC machined VTG adapters
• Clamps and Screws
This product is available in 2 options, OEM Porsche turbos or with 51.5mm turbo adapters for cars where the compressor wheel has been replaced, and compressor housing machined larger.

The Cayenne turbo / GTS 4.0ltr Intercoolers have been meticulously designed and engineered to fit exactly like the OEM units they replace. Utilising all factory mounting points, the installation is straightforward with a “drop-in fit” design. No cutting or modifications are required and there is no need for aftermarket shrouds or hoses. All mating OEM components can be reused and reinstalled.
The Thermal Dispersion Black finish is used to aid further the cooling efficiency of these Intercoolers and they are then sent to a special aerospace company where this special ceramic coating is applied. This unique coating rapidly disperses heat away from the intercoolers at an increased rate of about 15% compared to non-coated parts. In addition, this special coating gives the intercoolers a durable OEM stealth look behind the open front bumper air inlets.
CSF has integrated the charge pipe into the design of the top end tank with an aluminum welded pipe replacing the factory bolt-on plastic part which is sealed with an inner O-Ring. It has been stated that the OEM O-Rings may be a factory design flaw as these can fail. This failure causes boost leaks and triggers a check engine light which is quite surprising on such a new vehicle. These O-Rings have been known to already started showing signs of failure with only a few thousand miles on the odometer.
As with CSF’s other products the new Cayenne turbo / GTS Intercoolers feature 100% TIG-welded machined billet aluminum end tanks. This is a very important upgrade compared to the OEM crimped plastic composite end tanks and this feature is not only aesthetically pleasing, but is also stronger offering longevity and durability on high-performance vehicles. The CNC machined billet end tanks are ready to withstand increased boost pressures from bolt-on modifications, higher performance tunes, as well as upgraded turbochargers.

Turbocharged engines rely on a sealed and efficient intake system to deliver performance. Over time, individual components such as intercoolers, plastic pressure pipes and rubber connectors can degrade, leading to boost leaks, reduced efficiency and loss of power. This kit replaces all key components in one package, ensuring optimal airflow and long-term reliability.
What This Intercooler & Pressure Pipe Kit Does
The charge air system works by compressing air via the turbochargers, cooling it through intercoolers, and delivering it to the engine.
This kit ensures:
• Efficient cooling of compressed air via both intercoolers
• Consistent boost pressure through all connecting pipes
• Proper airflow from turbochargers to engine intake
• Reduced intake temperatures for improved combustion
• Reliable sealing across the entire boost system
Together, these components restore full turbo system efficiency and engine performance.
What Is Included in the Kit
• 2 x Intercoolers (left and right)
• 6 x Intercooler pressure pipes (charge air pipes)
• 2 x Rubber mounting adaptors
This complete set replaces all major airflow components between the turbochargers, intercoolers and intake system.
Why Intercooler and Boost System Components Fail
Turbocharged systems operate under high pressure and extreme temperatures. Over time, this leads to wear across multiple components.
Common issues include:
- Cracked plastic pressure pipes - Heat and boost pressure can cause plastic pipes to split or weaken.
- Boost leaks at connections - Seals and joints may degrade, allowing pressurised air to escape.
- Intercooler efficiency loss - Contamination or internal wear can reduce cooling performance.
- Rubber adaptor deterioration - Rubber components can harden, crack or lose sealing ability.
Symptoms of a Failing Charge Air System
• Loss of engine power
• Reduced turbo boost pressure
• Hissing or air leak noises under acceleration
• Poor throttle response
• Increased fuel consumption
• Engine warning lights related to boost pressure
Replacing all components together ensures a complete and reliable solution.
Why Upgrade to a Complete Kit
- All-in-One Solution - Replacing intercoolers, pipes and adaptors at the same time eliminates multiple
failure points.
- Restore Full Turbo Performance - Ensures proper boost pressure and airflow throughout the system.
