ESS Tuning was founded in Aremark, Norway in 1995, providing supercharger solutions to the mighty BMW platform. Since then, they've amassed a legendary reputation as the largest BMW supercharger system manufacturer in the world, and as a well-known innovator in the chip and ECU tuning sector with an extensive expertise in Bosch and Siemens engine control systems. In the quest for true uncompromised performance, no one rivals ESS Tuning.

The S85 G2-680 Gen.3 intercooled supercharger system comes with an especially developed cast aluminium manifold assembly with a integrated liquid to air chargecooler. A large capacity front mount heat exchanger and high performance circulation system cools the manifold mounted chargecooler.
The Gen.3 version of the S85 system has a different manifold casting with flow optimized, injection molded throttle body couplers in addition to a new 4" dual silicone intake system for increased overall system flow. Then Gen3. carries over the upgraded front mount heat exchanger with casted end tanks and beefed up aftercooler circulation system from the previous Gen.2 update of the kit.

I have used many mechanics over the years for the many different types of vehicles in our company fleet and southern BM is one of the very few workshops I can highly recommend. Andrew and his team are also really passionate about their work and it shows.

Touched base with Sean to do some coding work on my F85 X5M. Not only was he a whiz with the tech stuff, knowing his way around without any difficulty. Very rare to find someone like Sean - I happily rate and recommend this business for anyone.
