It seems that G-Power have been in the business of producing aftermarket kits for quite some time now; 30 years, to be more precise.
And with the round number reached, they released a very nice Mono-Kompressor system for the BMW M5 and M6.
This system only works with the V10 engine present on the previous generation of vehicles, and the power upgrades are substantial. The first stage kit brings out some 580 Hp, making for a 77 Hp increase, all for the price of €7.300.
Stage two brings more power but also a price increase. That’s 600 Hp and an additional €650, respectively. The third stage power kit comes with an intricate aluminium casting instead of the standard air box. There is also another jump in power, offering 620 to 640 Hp.
The next and final stage will round up the output at a nice 700 Hp, while also fitting a back pressure reduced exhaust system with racing catalysts. Not a bad way to celebrate 30 years of activity.
