Our EVO2 high-performance intercoolers (2 x [330mm x 222mm x 145mm] = 21,244cc). Are designed to provide a whopping 77% more charge air volume than the factory intercoolers. This translates into a significant increase in your vehicle's performance. Our specially designed Competition high performance intercooler core ensures excellent cooling characteristics. Even under extreme conditions, your engine will maintain the optimum temperature. Despite its impressive performance, our intercooler kit is surprisingly lightweight. Each of the two coolers weighs just 6.7 kg.
CAD designed cast aluminium freeform end boxes provide the best possible internal airflow and high pressure resistance of up to 6 bar (tested). Our kit includes a custom-fit carbon air duct that ensures the intercooler is optimally supplied with fresh air. This is crucial for maximum performance of your vehicle. The kit includes additional silicone hoses with an enlarged cross-section to optimize airflow.
Our intercoolers are finished with an anti-corrosion coating that not only ensures durability, but also provides excellent heat conduction properties. Our kit comes complete with new carbon air guides, silicone hoses and aluminium adapters. Installation is simple and replaces the factory intercoolers. This kit is specifically designed for racing and features a 70mm intake and exhaust for maximum performance.

Turbochargers, Intercoolers & Parts – Precision-Engineered Performance for Porsche Engines
A turbocharger increases your Porsche’s power and efficiency by forcing more air into the engine’s combustion chamber, while the intercooler cools that compressed air to improve performance and reliability. Together, these components deliver the exhilarating acceleration and responsiveness that define Porsche engineering.
At Design911, we offer a comprehensive selection of turbochargers, intercoolers, and related components for Porsche models old and new. Manufactured using high-grade materials and advanced balancing technology, our range ensures consistent boost pressure, superior cooling efficiency, and long-term durability under extreme conditions.
Whether you’re restoring a classic 911 Turbo, upgrading a Cayman for track use, or replacing worn components on a modern model, our high-quality turbo and intercooler parts guarantee unmatched performance and reliability.
What Do Turbochargers & Intercoolers Do?
Turbochargers and intercoolers work together to enhance engine power, efficiency, and response.
Core Functions:
- Turbocharger:
Compresses intake air to increase the engine’s air/fuel ratio, producing
greater power.
- Intercooler:
Reduces the temperature of compressed air before it enters the engine,
improving combustion and preventing knock.
- Associated Parts: Turbo hoses, valves, clamps, and cooling lines maintain consistent boost pressure and reliable airflow.
Together, these systems optimise power delivery, throttle response, and engine longevity — key to achieving Porsche’s hallmark driving experience.
Why Do Turbochargers & Intercoolers Fail?
Turbo and intercooler systems operate under extreme temperatures and pressure. Over time, wear and heat cycling can cause performance degradation or failure.
Common Causes of Failure Include:
- Oil
contamination or starvation damaging the turbo bearings.
- Boost
leaks from worn seals, cracked hoses, or gaskets.
- Intercooler
clogging due to debris or oil residue.
- Excessive
exhaust temperatures leading to turbine damage.
- Corrosion or heat fatigue from prolonged high-speed driving.
Symptoms of failure include whining noises, loss of power, blue or black exhaust smoke, poor boost response, or oil leaks around the turbo system. Addressing these early can prevent costly repairs and maintain performance.
Why Replace Components?
Replacing a worn turbocharger or intercooler with a precision-engineered, high-performance alternative restores full boost pressure, temperature control, and efficiency — ensuring your Porsche performs as intended.
Key Benefits:
- Restores boost pressure and throttle response.
- Improves air cooling and power delivery.
- Prevents oil and boost leaks.
- Constructed from lightweight, heat-resistant materials.
- Direct-fit
compatibility for Porsche 911, Cayman, Boxster, Macan, Panamera and more.
- Ideal for performance upgrades, maintenance, or rebuilds.
High-quality turbo and intercooler components are essential for reliable, sustained performance in both road and track environments.
Highlights:
- Turbochargers, intercoolers & related parts for Porsche models.
- Precision-engineered to enhance airflow, boost, and cooling.
- Heat-resistant construction ensures durability and performance.
- Perfect for maintenance, upgrades, or complete rebuilds.
- Supports Porsche 911, Cayman, Boxster, Panamera and more.
- Optimised for performance and reliability under extreme load.
