ByDesign 991 Turbo Performance Intercoolers


Developed specifically to ByDesign specs with shrouds and configured to require no cutting for factory-like fitment. 4.5 inch intercooler cores with billet machined end tanks and carbon shrouds developed in house deliver premium results.



The 991 Turbo is capable of big power. Upgrading the exhaust is usually the first step, and a tune will extract gobs of torque, but upgrading the intercooler supports the increased power by lowering intake air temperatures for sustained power and safety. Expect new heights in power with decreased turbo lag. Don’t just take our word for it, there are success stories internet wide with great results – up to 1,000 ft-lbs of torque with fueling limits being the limiting factor!

We recommend these intercoolers for any 991 Turbo getting tuned, and recommend a tune for any car receiving these intercoolers to realize maximum power. Please contact us for more information and consultation on the best hardware and software setup for your 991 Turbo.

Why ByDesign? Their strong community presence and continued dedication to the Porsche market resonates with us. Commonly found active in the Rennlist forum and online world, Sam is known for his experience and professionalism. These intercoolers have been tested and proven on the track, verified with several different tuners, and meet the strict requirements we have for customer service, quality, and performance.
