      Great value
      I recently had to replace the starter on my 2001 325i E46 with about 150k miles. While I had the intake off, I figured it would be a good time to replace the CCV because I was unsure if it had ever been done. My old CCV literally fell apart as I removed it, so I'm glad I replaced it. The new parts were a little tough to put together, but overall came together well enough. A lot can be forgiven for the price. I would recommend assembling the system before installing in your vehicle to get a good sense of how it all goes together and to hopefully loosen up the fittings just a tad before installation. 50skid on youtube has a great DIY for doing this job. I only finished this job yesterday, but my car has been running great. I can't yet confirm, but this may have solved my running lean problem.

      Cheap plastic parts -- good fit
      They are what they are: Cheap plastic parts. They fit, but long-term durability will be a challenge. Probably will buy from FCP Euro going forward (and just did for a fuel line replacement).

      Does not connect
      First the hoses do not connect together causing all kinds of vacuum leaks. There is no rifling in the diaphragm so oil leaks back up. Cheap piece of plastic

      Amazon size charts need help
      Size: Small, Color: Dark Denim
      The dress is sharp. Well made. The Amazon size guide and AI size helper not so great. It was suggested to me to order a size large. Well I knew that was wrong so I went with the medium due to size chart. Still way too big. Had to return the medium and order a small . That also was too big and now had to order an XS . What a hassle. Please correct the size chart. Would very much appreciate the accessories listed that the model is wearing such as who’s boots she is wearing
