Performance Upgrades
Engine tuning and performance upgrades have a long tradition at AC Schnitzer. To be on the safe side however, we prefer not to extract the maximum possible power but instead ensure greater robustness, which means a longer life of the engine. Many of our diesel performance upgrades are therefore designed for an increase in torque rather than an increase in horsepower. Because torque is what you feel when for example you're "pressed back in the seat" on pulling away.
Warranty
For engines and performance upgrades, we offer a warranty of two years from the date of first registration, up to a kilometre reading of 100,000 km (for M-vehicles, two years up to a kilometre reading of 60,000 km) on all components excluded from the BMW warranty.
