Good Quality - Perfect Fit for 2009 BMW 335i E93 N54
While installing a Mishimoto oil catch can, the removal of the OEM PCV flapper didn't go as planned. The connectors on both sides snapped off. I was glad I could find a replacement on Amazon. When the vent hose arrived, I compared it side by side with OEM. They looked identical. I only needed the connector for the valve cover side to install the hose for the oil can. It was a perfect fit. It fit nicely and securely with an audible click. It has been about a month, and there are no issues.

Top quality, Great price
Went on easy (advice: get on the other side of it and pull instead of pushing for the top connection, of you are having issues getting it to click in), tough to take off (the other issue I was working on when I changed this still existed so I had to re-do things), but that's the nature of this type of connector. The important part is that it came back off and went back on...and off and on again...without breaking. Twist as you squeeze the connector release, it helps. Great quality product. I will look for this brand on other parts in the future.

Great BMW Alternative for a Reasonable Price
Thankfully, there's little to go wrong inside this vent hose and flapper. This aftermarket part fits and works just as well as the genuine BMW hose. Note that the clips that snap onto the valve-cover and intake system are fragile, just the same as the genuine part. So be careful if you remove the hose later.

Good fit
My previous PCV hose was leaking old, This replacement part fits and locks on tight. There are some parts I would prefer OEM like gaskets. I would say this is a good non OEM option part.
