Switzer Performance has launched an upgrade kit for the BMW M5 (F10) available for 6,995 USD.
The tuner has taken a break from its aftermarket programs for the Nissan GT-R and various Porsche models to focus on the German high-performance sedan. The car's soundtrack has been improved thanks to a new high-performance, stainless steel exhaust system.
It also features high-flow drop-in air filters and a removable engine control module working together with the stock systems for a higher boost from the engine's twin turbos. While the standard BMW M5's V8 4.4-liter twin-turbo produces 560 HP (412 kW) and 502 lb-ft (680 Nm), the version modified by Switzer churns 700 HP (515 kW) and 640 lb-ft (867 Nm).
The tuner has also announced starting this summer they will offer carbon-nano brake pads and Signature alloys for all 2013MY (and later) M5s.
