The cowl trim panel at the base of the windshield is a known wear item on the BMW E46. Years of exposure to heat, UV rays, and the elements cause the original plastic to dry out, become brittle, and eventually crack or warp�detracting from an otherwise clean engine bay and windshield area.

This high-quality aftermarket replacement from Bremmen Parts is designed to restore a factory-fresh appearance on E46 models. Featuring a precise, OEM-style fit along the windshield and firewall, it properly seals the cowl area while instantly improving the overall look of the vehicle. It�s an ideal replacement when addressing cosmetic aging, damaged trim, or during routine maintenance or windshield service.

  • The large 1.8+ gallon reservoir
  • Rigid mount can be easily detached if needed by its spring loaded quick releases.
  • For offroad use only.
  • Does not include any fluid.

This methanol injection system fits the following BMWs:
