The AWE ColdFront Intercooler Kit leverages generations of Porsche engineering, dating back to the 996. Cast end tanks designed in house, specially designed cores, power testing, dyno fueled refinement, and more. Compared to the 991s stock intercoolers, the AWE ColdFront Intercooler Kit's cores are 17% larger (523 cubic inches vs 448 cubic inches). In contrast to the stock cores, the AWE ColdFront Intercoolers are a high flow bar and plate style and are built to our charge row and fin count specifications. These specifications result in 20% reduced air temperatures and 50% improved pressure resistance through the cores. These lowered air temperatures and freer flow allowed the AWE Porsche 991 Turbo S to achieve dyno verified max gains of 26 HP and 21 lb ft of torque at the crank when used with the AWE 991 Turbo Performance Exhaust and S FLO Carbon Intake, and performance software, translating to almost a full second reduction in 60 130 mph acceleration times. AWE designed the biggest cores the 991 TT rear fenders could fit, and as a result of the size difference, the OEM ducts couldnt be utilized. To feed fresh, cooler air to the intercooler cores, proper flowing ducts are mandatory. The result: straightforward and bolt in carbon fiber, seamlessly mating to the AWE ColdFront Intercoolers. No trimming or cutting necessary the AWE Fitment Guarantee remains intact. In addition to the superior core and end tank design, the AWE ColdFront Intercooler Kit for the Porsche 991TT also features thick wall 6 ply silicone hoses with gentle curves to prevent bursting under pressure. They are attached to the factory intake and turbos by stainless steel high force t bolt clamps, and a molded lip is integrated where the hoses meet the turbos to duplicate the factory locking mechanism. AWE hoses use a Nomex braiding, instead of more common polyester, for superior strength. Please note, the AWE ColdFront Intercooler Kit for the Porsche 991TT is for racing use only.
