Review on 🔧 5 Piece Crankcase Vent Valve Breather Hose Kit - Compatible with BMW E46, E39, E60 320i, 323i, 325, 325i, 325ci, 328i, 330i, 330ci, 330xi, 525i, 528i - PCV Ventilation Separator Value Pack by Maalik Harris

So these replacement parts fit my E46 2002 perfectly. However, at first I thought that one of the ends of the hose was bent 180 degrees. I pushed/pulled with such force to align them that I thought I would break the pieces. They're not as flexible as they seem. Finally, after about 20 minutes of fiddling, the end of one of the hose fittings turned. They're so stiff they look and feel like they're made out of one piece, but they're not. So if necessary try to gently twist the ends of the hose, they will be stiff but they will twist. I would even spray them with WD-40 next time. I gave this product 5 stars because my machine ended up working great and the parts fit great at a great price. However, if I could I would give the BMW engineers zero stars for the design and interchangeability.
