Buena calidad

These parts, while very close to original, are off enough to make things difficult. Primarily, the o- rings were too thick and required any insane amount of pressure to connect. I even had to reuse the old o-ring on one fitting, and reuse a complete end from another old hose. The nipple on one fitting was molded about 5 degrees off, which made installation very difficult and put undue strain on the pipe. Overall, I wish I would have spent a little more on higher end aftermarket pieces, or even OEM.UPDATE:Seller, GWA auto parts, did a great job of remedying my issues. They took the time to contact me, figure out the issue to current future issues with the parts, offered a partial credit, and were polite and professional the whole way through.

I checked the compatibility list twice just now and, sure enough, my 2002 E53 (X5) is on the list. However, and I realize it's hard to see from the camera angle, but trust me when I say the hose is too short. I should have taken it back off and put them together, but I just don't have the energy to do so after spending too much time already fighting with the connections (which, like other reviewers, I found to be improperly sized and difficult to attach, especially the nightmare hoses that go under the intake manifold). You get what you pay for. You've been warned.

Do yourself a favor and get the actual BMW parts. Several of the connections we're slightly off and made it so they did not snap into place, but what was worse is that half of the O rings were way too big. This made it such a hassle trying to secure these connections, especially the ones under the intake. Luckily I had an O ring kit and could make it work. But overall several of the dimensions were just off and you don't want to struggle with it and "make it work". Trust me, I am all for cheap parts, but if you can afford the better parts for this job, do it.
