Engineered for multi-directional pliability, the protector conforms to the knee for a snug and secure fit, and delivers reliable protection.
  • Ventilated Chassis Design: The chassis features a 3D mesh front panel for superior levels of ventilation and airflow, along with abrasion-resistant fabric that covers the knee area.
  • Stretch Mesh, Ventilated Construction: Soft, stretch mesh at the rear of the lower legs provides a comfortable fit for riders with various calf sizes, while the open knee construction behind the knee helps to prevent heat build-up while maximizes ventilation.
  • Extended Coverage: Extra side padding for extended coverage.

  • USDA Certified Biobased, eco-friendly, and sustainable impact absorbing material.
  • Extra side padding for extended coverage.

Direct Fit and good quality
Color: Single Slat Gloss Black, Size: 2002-2005 E46
For anyone that has owned an E46 knows that even the stock kidney grills are brittle plastic. This aftermarket is about the same quality as stock. It is a direct fit and has the clips where they are supposed to be to keep them in place. The look is also pretty nice. This one is all black and actually looks nice on my black E46. I would recommend especially for the price and shipping was fast.
