If you're doing this yourself, watch a YouTube video first. The part itself is a 10/10 fit. BMW purists shouldn't worry.

Easy to assemble

I was worried about assembling the fittings, but they went on smooth. Just take your time cutting the hose so it doesn't fray.

Better than Alum?

I debated getting an aluminum one but stuck with this. It’s been 2,000 miles and it’s bone dry. Very impressed so far.

Nice flexibility

For a PTFE hose, this is surprisingly flexible. Was able to route it through some tight spots in the engine bay without kinking.
