The very light cooling cores have inner turbulators for an optimal cooling effect as well as lamellar structure for perfect usage of the airflow. An excellent balance regarding cooling effect, weight, robustness and price. The casted Aluminium Tanks are made of 3mm thick Aluminium cast and can resist highest boost pressure.
These Models have matte instead of polished housings. All Intercoolers are tested to withstand 5 Bar pressure.* The Core size given in the name is a measurement for comparison to common Bar-and-Plate Intercoolers. The new Fin-and-Tube Cores have smaller cores due to their construction, which give an advantage regarding the weight and responding qualities (smaller volume).
The Fin-and-Tube Cores are smaller in reality but their size is still comparable to Bar-and-Plate because the difference in volume is balanced due to the better cooling effect. You'll receive with a 1:1 swap a better performance and response quality!
