Worked good but some of the hoses feel brittle and did not have exact 1:1 fitment and dimensions as OEM BMW parts have. But I got them to fit without much fuss and haven’t had any issues.

In the end, these parts fit my 2002 E46 perfect. At first however, I thought one of the hose ends was off by 180 degrees. I was pushing/pulling with so much force to get them lined up that I thought I was going to snap the parts. They’re not as flexible as they look. Finally after about 20-mins of messing around, the end of one of the hose fittings actually rotated. They’re so stiff that they look and feel like they’re formed from one pieces, but that’s not true. So if you need to, carefully try to rotate the hose ends, they’ll be stiff, but they’ll rotate. I would even spray WD-40 on them next time.I gave this product a 5-star because in the end my car is running great and the parts fit fine at an awesome price. However, If I could, I would give the engineers at BMW a zero star for the design and ease of replacement.

would have been great replacment for all my hoses,good value compared to buying each hose seperatly. make sure to check the connecting ends, one was broken and i could not use. unfortunatly, i had to return the entire kit, ended up going to local auto parts store.

easy installation took me five minutes and took away my dreaded p0171 code!

These valves have differences gen1 or gen2. To do this, you need to check the software version in the engine block. Pay attention to this. If you install the wrong system, it will not work as it should.

I ordered the non OEM kit for replacing the oil separator and vacuum pcv system on Amazon. It It was around 30 bucks, and I figured, hey, why not? Some of the people on the reviews mentioned o-rings that didn't fit, and that there was an inability to push them into the tube openings.In the process of taking the original pcv tubing apart, I realized that the quick connect convenience that they offered suffered substantially over the last 18 years.Trying to push the new fittings into the old tubes was absolutely impossible. Silicone lubricant, heat, muscle. NOTHING was going to make those tubes with the o-rings go into those old tubes.Since these ARE just vacuum tubes, I decided to make a move, since the so-called customer service for the Amazon vendor TOTALLY dropped the ball on any repair assistance correspondence.I took out the o-rings completely, and applied RTV sealant in the places where the o-ring would have made contact. Pressed the tubes in without much resistance, and... voila! Sealed, connected tubes, still clicked in with the fastener!I put everything back together, and I'm rolling down the road. Smooth as silk.So, someone might say that it's going to be a mess to get these apart if I need to service them in the future. My response is, I've NEVER been able to successfully disconnect or reconnect these tubes before, and I can't see any occasion that I would need to. And, if I DID, I'd tear off the RTV and apply another bead for reconnecting. RTV is cheap.Any objections to this method? I used an RTV that was safe for sensors,and I feel confident that it's not obstructing anything. And it's working perfectly

I installed this on my 2001 525i and everything matched up just like it should!Not exactly the easiest job. It is recommended that you pull the intake manifold but I was able to do it without doing so. It just made it a bit more difficult to run a couple of the hoses but I made it work.Overall, can't beat the price!

My son’s car is an e46 325xi and The 50’s Kid guy on YT has a 330 I think. So there were some differences but the video does a good job of explaining the process. Overall a medium difficulty job. I did it in January or February and it was pretty cold here in Michigan. Makes the fingers a little less flexy. I used a small butane torch to soften the plastic before bending and silicone spray to make the washers slip on with no trouble.
