Did not fit e90 2006 330i, n52 engine
For what it's worth, the quality of the hose seemed good, so that's why I gave 3 stars, but:
It did not fit my e90 2006 330i, n52 engine. Took the car to the shop to replace broken OEM hose. I provided the hose. It did not fit, so I ended up paying the shop for a hose, and probably extra time because it sat on the lift waiting for the one they ordered.

Didn’t fit but I made it fit.
The part appears decently made in China. The end that terminates below the oil filter would not mount (too tight). I gently sanded the o-ring groove, lubricated and I put the part in freezer. After two hours of sanding the groove I got the part seated. Good thing I was patient today. Pain in the butt.

Trusted reliable brand
Size: 5 Liter, Style: 1 Pack, Configuration: 5W-30
I recently used LIQUI MOLY Molygen New Generation 5W-30 for an oil change and overall I’m very impressed with the quality. The oil feels like a premium product and the difference in engine smoothness was noticeable almost immediately after the change. The engine runs quieter and smoother, especially during cold starts. This oil uses advanced additive technology designed to reduce friction and protect internal engine components, which helps improve efficiency and extend engine life. It also helps prevent deposits and keeps the engine cleaner over time. ()
Another thing I like is that it maintains stable viscosity even under high temperatures and heavy driving conditions. It provides excellent lubrication and wear protection while also helping improve fuel efficiency. The oil is also compatible with modern engines, including turbocharged applications, this is a high-quality synthetic motor oil that provides excellent protection and performance. If you’re looking for a reliable oil that keeps the engine running smoothly and helps reduce wear, this is definitely a great option and worth the price.
