Under the hood, Kneißler equips the M3 with a supercharger that enables the engine to produce 459 hp and 498 Nm of torque.

Kneißler Autotechnik has unveiled several performance options for the BMW M3 E46.

Under the hood, Kneißler equips the M3 with a supercharger, a charge air cooler, and revised engine electronics which allow the 3.2-liter inline-six to produce 459 hp and 498 Nm of torque. While the €13,000 price tag sounds steep, the performance is likely breathtaking.

To reign in the added power, Kneißler offers a high performance Stoptech braking system with six piston calipers clamping onto two-piece slotted discs that measure 380x32mm (€3852). At the rear, four piston calipers grab onto massive 355x32mm discs (€3103). The finishing touch is a set of innovative brake caliper air vent plugs by Stahlbus (€109).

Other performance options include a Kneißler sport muffler (€1350), a KW coilover suspension kit (€1749), and KW- sport stabilizers (€419).

In terms of styling, the exterior was thankfully left alone.  However Kneißler offers an LSD wing door conversion kit (€1990) and attractive 20-inch Oxigin wheels outfitted with high performance Hankook tires (€2723).

[UPDATE  04.09.2009]  The supercharger system which the upgrade for the BMW M3 E46 is based on, has been installed by the company G-POWER. The featured supercharger is an ASA TurboMex.
