DesignTek Porsche intercoolers produces high-flow rate and dramatic temperature reduction which are mainly contributed by two key factors. Firstly, the great temperature reduction is accomplished by a 40% larger than stock sized intercooler cores in which each core has the capacity flow rate of 750 CFM. Secondly, which in our opinion is the most important element of an IC; the inlet/outlet end-tanks. Our end-tanks are a one piece cast aluminium construction design, formed with little to no corners and are also fully polished on the insides to increase air velocity; therefore minimizes welding points and greatly increases air flow and reduction in pressure drop which yields to improved efficiency. Also please note that all of our intercoolers come only in high polished finished for that uncompromised appearance.

Porsche Performance Radiators - Engine Cooling & Thermal Control Upgrades
Radiators are a critical part of the engine cooling system, responsible for dissipating heat and maintaining optimal operating temperatures. In performance-driven, tuned, or high-mileage Porsche engines, upgraded radiators play a vital role in preventing overheating, reducing thermal stress, and protecting engine components under sustained load.
Available from Design911, Porsche performance radiators are engineered to deliver increased cooling efficiency, improved airflow, and enhanced durability—making them essential upgrades for road, track, and high-performance applications.
What Do Radiators Do?
Radiators regulate engine temperature by transferring heat away from the coolant.
Core Functions:
- Dissipate engine heat efficiently.
- Maintain stable operating temperatures.
- Prevent overheating under load.
- Support consistent engine performance.
- Protect internal engine components from heat damage.
Effective cooling is essential for engine reliability and longevity.
Why Do Radiators Fail?
Standard radiators can degrade over time due to age,
contamination, and increased thermal demand. Common failure causes include:
- Internal blockage from debris or sediment.
- External fin corrosion or damage.
- Coolant leaks from plastic end tanks or seals.
- Reduced efficiency due to age and contamination.
- Increased heat load from tuned or track-driven engines.
A failing radiator can lead to overheating, coolant loss, and serious engine damage if left unresolved.
Why Upgrade to a Performance Radiator?
Performance radiators are designed to handle higher thermal loads more effectively.
Upgrade Benefits:
- Increased cooling capacity and heat dissipation.
- Improved airflow and coolant flow efficiency.
- Stronger materials for enhanced durability.
- Reduced risk of overheating during spirited or track driving.
- Ideal upgrade for tuned and high-output engines.
Upgrading the radiator helps protect engine reliability while supporting performance enhancements.
Highlights
- Porsche performance radiator upgrades
- Improved cooling efficiency and heat management
- Designed for tuned and high-performance engines
- Enhanced durability and long service life
- Essential upgrade for track and performance use
