1999 BMW 528i Fit and works like Original BMW-Pleasantly Surprised
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.

Cheap Replacement
These are an easy replacement for anyone who owns a BMW m52/m54 engine that has PCV issues. My car was burning about 1 quart every 1,000 miles. The parts are direct fit and install fairly easy. If there is resistance, lube the hole or o-ring up with some grease and it will slide in easier. Took me about 2 hours start to finish. My mechanic recommended that I remove the intake manifold to do the job. I don’t see how you could do it without removing the intake manifold. These parts probably won’t last as long as true BMW parts but on a 20 year old car I don’t see the benefit in using genuine BMW parts. Cheap stuff will suffice; worst case it doesn’t last quite as long.

NOT TOO HARD TO INSTALL...
This CCV kit seems adequate. People say that because the hoses supplied with these kits are more brittle than the genuine BMW parts, these are tough to install... But they're really not. The ends on these hoses SWIVEL and you can sort of eyeball which way you need the fitting to be pointing BEFORE you put them on your manifold... They swivel, but they're tight and it takes a little force to turn them. ALSO, a little dab of silicone gel or a spray of silicone out of the can, into the fittings on these makes a world of difference when clicking them on... For the price, I highly recommend the kit.

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.
