PSDesigns Velocity Stack Conversion (E46 M3)
The intake noise is a distinctive character of the E46 M3 CSL, which had a carbon airbox developed specifically for it by BMW Motorsport. PSDesigns has developed a kit that takes that intake noise one step further – bare velocity stacks. With no restrictions and nothing to muffle the incredible intake noise that the S54’s individual throttle bodies make, this is a great upgrade for any E46 M3.
The Kit includes all mechanical components to convert the S54 engine to Velocity Stacks.
