Great value. Seamless installation.
I am absolutely satisfied for the price. The quality is appears to be comparable. I won’t know their ability obviously until a year from now or so. They are indeed a pain in the ass to replace. Actual installation of new parts was seamless.

The Hose Ends Rotate
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.

great replacment
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.

Good parts
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.

Don't worry things fit very well
I was worried about negative comments about the fitting of the product. I did not have any of these problems. All the pipes were the same length and everything snap fit together. Also there were no problems with o rings being too big. I hit them up With a little lube to make them come together. I did my assembly with the engine out of the car because it was a swap. This made things very easy and can see it would be more difficult when the engine is in the car. It might explain why some had size problems.

O-rings are too large to allow for reasonable fitment
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

Good product. Not a bad job.
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.

Fits the BMW 525i E39 models.
Product was used for preventative maintenance (i.e. replacing the hoses before they broke or cracked). Packaging was good, plenty of bubble wrap and arrived all in one package. The process of replacing the hoses is tedious so plan on at least a few hours of work and removing some of the surrounding engine parts. (There are plenty of YouTube videos to assistance & guiding). Would recommend this brand and would buy again (but hopefully I won't have to buy again until several years from now).

02後期46の325です。嵌合部が少しキツい。インマニ外して作業したら問題無いかも…。純正も欠品出てるし、値段的にもセットは有り難い。オイルレベルゲージのチューブのところのゴムキャップは付属してませんでした。
