Designed in-house
The AWE Tuning 991TT Performance Intercooler Kit leverage generations of Porsche intercooler engineering, dating back to the 996. Cast end tanks designed in-house using sophisticated CAD (Computer Aided Design) and CFD (Computational Fluid Dynamics) software, specially designed cores, power testing and dyno-fueled refinement, and more.
Goals set, torture testing executed, Porsche 991 Turbo Performance Intercooler born.
More Volume. More Fins. More Cooling. More Performance.
Compared to the 991's stock intercoolers, the AWE Tuning Porsche 991TT Performance Intercoolers cores are 17% larger (523 cubic inches vs 448 cubic inches). In contrast to the stock cores, AWE Tuning Porsche 991TT Performance 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 Tuning Porsche 991 Turbo S to achieve dyno-verified max gains of 26 HP and 21 ft-lbs of torque at the crank when used with the AWE Tuning 991 Turbo Performance Exhaust and S-FLO Carbon Intake, and G.I.A.C Stage 2 software, translating to almost a full second reduction in 60-130mph acceleration times.
More Carbon Fiber.
We've designed the biggest cores the 991TT rear fenders could fit, and as a result of the size difference, the OEM ducts couldn't be utilized. To feed fresh, cooler air to the intercooler cores, proper flowing ducts are mandatory. Cue AWE Tuning Carbon Fiber ducts. The result: straightforward and bolt-in, seamlessly mating to the AWE Tuning Performance Intercoolers. No trimming or cutting necessary and the AWE Tuning Fitment Guarantee.
Installation Hardware
In addition to the superior core and end tank design, the AWE Tuning Porsche 991TT Performance Intercooler Kit 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. Further, our hoses use a Nomex braiding, instead of more common polyester, for superior strength. The very best materials and industry leading engineering separate this kit from all others on the market.
Whether you're simply running enhanced software, or planning on a larger turbo upgrade for your car, the AWE Tuning Porsche 991TT Performance Intercoolers are exactly what you need to deliver proven, consistent power.

Buy it
If you're looking for a comfortable thick and nice turtle neck this is the one. It's nice and form fitting nice weight to it to keep you warm. But not to thick that you cant just wear it on a regular sunny day if you wanted. The design pattern Is also very nice. Can dress it up or down. I bought the black and then immediately bought the rust orange color for my friend once he tried on mine he wanted one immediately so I gifted him one. He loves it. Definitely worth the buy. Excellent quality. I bought a Large 5"11 165lbs

A true turtleneck that retains a snug high neck.
Color: White, Size: X-Large
I've found this brand to have gotten better over the years as far as offering the American market what it needs in terms of realistic sizing. I only wish they'd realize that there are a lot of us who are long in the back and arms where my only choice is to go a size up and sacrifice a slim fit for sleeves that are long enough plus a back that doesn't go up past my waist just because I reach up for something, that and I like to be warm. So these are such nice quality turtlenecks that it's hard to complain about but maybe the company will read this. The snug neck stays up is plus number one since that's why I'm buying a full neck. They come with very nice weaves in the fabric, good enough for casual or formal wear. Finally the warmth you seek is there but I've worn them in what most would think isn't the right temp for a turtleneck. Also they have them in white! Yes, a lot of others just don't for reasons I can't fathom, and the pic you're seeing is accurate, these will form to your shape without being ridiculously thin material. Several washes later and they are as fine a garment as when I first wore them. I've only found one other brand that compares to these but it's much more expensive, COOFANDY is affordable in these times of expensive everything. Warm but also a lightweight shirt, I've gotten them really dirty with actual dirt and it washes out so well you'd never know it. Don't let my taking off one star stop you, try one yourself and you'll be coming back for more.
