Modern turbocharged Porsche engines rely on a highly efficient and sealed intake system to deliver performance. Over time, components such as intercoolers, plastic pressure pipes and rubber connectors can degrade, leading to boost leaks, reduced cooling efficiency and loss of power. This complete kit replaces all key components in one package to restore performance and reliability.
What This Intercooler & Pressure Pipe Kit Does
The charge air system compresses air via the turbochargers, cools it through intercoolers and delivers it into the engine for combustion.
This kit ensures:
• Efficient cooling of compressed air via both intercoolers
• Consistent and leak-free boost pressure across all pipe connections
• Proper airflow from turbochargers to intake system
• Reduced intake temperatures for improved combustion efficiency
• Reliable sealing and mounting across the entire system
Replacing the full system helps maintain optimal turbo performance and engine efficiency.
What Is Included in the Kit
• 2 x Intercooler
• 2 x Intercoolers Pressure Hose Upper (left and right)
• 2 x Intercooler Pressure Hose Lower (left and right)
• 2 x Intercooler to Cut off Valve Pressure Pipe
This complete set replaces all major airflow and connection
components within the turbo intake system
SPECIFICATIONS
• 3D Scanned, CAD Designed and 3D-printed prototype; Tested
in collaboration with automotive engineering firm RK Autowerks. Providing the
absolute best fitting Porsche 991 Turbo intercoolers available in the
aftermarket.
• CFD tested (Computational Fluid Dynamics) cast end tanks with several post
machining processes for the absolute best tolerance specifications and maximum
airflow distribution throughout the core.
• All OEM mounting points are retained with the OEM clip-in hardware design.
Utilizing factory hardware, for an OEM-level installation. (CSF Exclusive)
• OEM style "Quick-Connect" machined fittings for precise fitment,
lock and seal.
• Finished with an aerospace grade, nano-particle, heat dispersion coating that
dissipates heat ~35% better than uncoated raw aluminum. (~ $500.00 value)
• "Drop-in fitment", no modifications or grinding to metal brackets,
etc.
• (Requires slight trimming to the plastic intercooler shrouds)
• Individually leak / pressure tested to 120 PSI
• Individually inspected for quality control
• Instruction manual included
• Specifically cut foam protective packaging to ensure damage free shipment
• Manufactured completely in house by CSF; a tier 1 OEM manufacturer with over
50 years of cooling system manufacturing experience. Over 500,000 units sold
every year and over 40 million units sold globally.
CORE DESIGN
• 8mm fin height louvered external fin with 6.5mm fin height staggered internal
fin. Designed to maximize surface area contact and heat dissipation.
• Wind tunnel optimized and dyno tested for low pressure drop with best
performance
• CSF's "Ultimate-Boost" High-performance bar / plate core. Built in
house and pressure tested to 120 PSI
• 4.53-inch thick core compared to OEM's 3.15-inch core (115mm vs 80mm)
• Increased flow area by 43.75%
• Increased surface area by 70% (8.5m^2 vs. 5.0m^2)
• Built in-house by CSF (Only high-performance company to manufacture their own
intercooler cores)
Why Intercooler and Boost System Components Fail
Turbocharged systems operate under high pressure and extreme temperatures, which leads to wear across multiple components.
Common issues include:
- Cracked or weakened pressure pipes - Pipes can split or degrade over time due to heat and pressure.
- Boost leaks at joints and seals - Connections and sealing surfaces can wear, causing pressure loss.
- Intercooler efficiency loss - Internal contamination or ageing reduces cooling effectiveness.
- Rubber adaptor wear - Rubber components can harden, crack or lose flexibility.
Symptoms of a Failing Charge Air System
• Loss of engine power and acceleration
• Reduced turbo boost pressure
• Hissing noises under load
• Poor throttle response
• Increased fuel consumption
• Engine warning lights related to boost pressure
Replacing all components together ensures a complete and long-lasting solution.
Why Upgrade to a Complete Kit
- All-in-One Replacement - Eliminates the need to diagnose and replace individual failing components.
- Restore Full Performance - Ensures correct boost pressure, airflow and cooling efficiency.
- Prevent Future Failures - Replaces ageing parts across the entire system to avoid repeat repairs.
- Improve Engine Efficiency - Optimised airflow and cooling improve combustion and power delivery.
- Ideal for Preventative Maintenance or Performance Builds - Suitable for both standard maintenance and performance-focused upgrades.
