A good replacement they fit perfect and I haven't had any issues with them yet
They fit great in my 2000 bmw 528i and I have had them for a couple months now and they have had no issues.

Fits L494 5.0L Upper Coolant Line LR034624
Fits L494 supercharged 5.0L upper coolant line LR034624. Comes with o-ring which is not as robust than factory but seals perfectly.

It says it won’t fit my vehicle but it does
I don’t think that the amazon vehicle match is accurate. I bought this and it fits my 2005 bmw 320i. It was a very convenient and easy fix instead of replacing the whole hose.
