1999 BMW 528i M52TU Engine. Pleasantly surprised and impressed. Everything fit as it should. Yes, one connector pipe took a bit more pressure to get it to "click" and lock, but it did click and lock..and better tight to insure no vacuum leak. Definitely works well and stopped the vacuum leak that old system had. Would recommend especially since price point might lead one to think that quality is not that good, but I'm glad I didn't spend any more on something else. Highly recommend.

Test fit to make sure it connects

When I revived it I thought it had looked a little too small until I compared it, I test fitted it and at first I thought it was a tad bit bigger but realized the more I pushed it in the more it went very tight fit and my car is running healthy. Installation is a pain but go to YouTube and search the “” the 50’s kid”” Who has two methods to getting them on, I went the intake removal route to replace additional parts.
