BMW M3 CS (1999-2003, E46)

Technical Notes

Numerous motoring press have reported on the popular upgrade for the E46 M3, with a 29 BHP increase normally achieved at 6400 Rpm it has to be one of the most impressive upgrades for any normally aspirated engine. By attaining the standard maximum power nearly 1400 Rpm lower the engine does not need to be revved as hard to get the same acceleration. However if you do use the full rev range the performance eclipses that of the standard M3.
