Evosport Crankshaft Pulley

Parasitic power loss from driving engine accessories like the water pump, power steering, alternator and air conditioning on your E90/E92 M3 can be remedied with a lightweight crankshaft pulley from Evosport. The Evosport Power Pulley System uses a custom-engineered pulley machined from T-6061 billet aluminum designed not to alter factory harmonics or dampening. The upgrade includes the necessary replacement belts and hardware. It is easily reversible should the need arise and includes a three-year warranty covering the part's craftsmanship. $395

Originally debuted on the 2001 E39 5 Series, BMW's headlamp "haloes" have become part of a signature look in the BMW lineup. European Auto Source (EAS) and Custom Angel Eyes have devised the world's first plug-and-play solution for upgrading the color temperature and lighting output to produce a bright, uniform white light from your BMW's headlamps-reportedly even brighter than stock. Specific kits are available for E39 and E60 5 Series, E53 X5, E63/E64 6 Series, E65/E66 7 Series, E46 and E90/E92 3 Series. $299

Based on the company's original Sports Label exhaust systems introduced last year, Remus Sport Exhaust has introduced its new "U.S. Sound" system for the new E90/92/93 M3 and the E39 M5. These exhausts are developed in Remus' sound dyno cell at home in Barnbach, Austria, in order to get real-time digital documentation of the exhaust note both within the cabin and outside the car. The U.S. Sound system is also designed to flow easier than the stock system and reduce backpressure even over the company's Sports Label systems. It's louder than the Sports Label as well, giving the understated M3 exhaust note the high-performance yelp many feel it lacks. M3 E90/E92: $1,422; M5 (E39): $1,198
