didn't fit m,y vehicle

First, the top of Amazon says this does not fit my 2013 BMW 550I 4.4L but the part description says it does. I can confirm it does. However, in hindsight I should have just bought the upper hoses and not the 4 piece set. When removing mine for the dreaded coolant Y repair, I found both upper hoses fell apart as the plastic was brittle from heat. I figured I might as well replace all. However, the lower hoses are exponentially more difficult to replace and I elected not to replace them and instead only replace the top hoses and fittings, snapping the existing lower hoses into the tee of the new hoses. Doing this worked great. In hindsight, maybe I should have just replaced the broken plastic part with some silicone hose and some hose clamps... Maybe next time.

very good part great seller

Used them to make a catch can

Very good thanks

I gave a lower score on easy to install because the car itself. It was 3-4 hours to install with moderate automotive repair experience, but the product was as described and worked perfectly.

Llegó bien empacado, en óptimas condiciones y antes de lo esperado

Worked great on my 2009 BMW 750i N63 engine. Turns out my old pipes were leaking so this was a quick and easy fix. no more smoking out of the tailpipes or adding a quart of oil every few weeks. very happy.
