FCP and Rein is the only way to go, this part fit perfect and I’ve been running my car everyday since the install and had 0 problems with this part

Replaced all the hoses and cooling parts on my E39 with an unknown service history, this was great, didn't have to fight it, make sure you tuck and locate everything like oem and it won't get eaten by the accessory drive!

Fit perfectly, no issues. Time will tell how long it lasts. Old one had broken/cracked right where it enters the block at the front driver's side of the engine, causing slow bug nagging coolant leak (common failure).

Great quality and fit perfectly

relatively easy to replace, part worked as expected!

As expected, the pipe fitted perfectly without any issues. All holes lined up without any stresses. Highly recommended. I recommend applying a thin coat of Silicon grease fro easy insertion and proper Coolant to prevent pipes and seals deterioration as unmaintained coolant is the number one reason for the damages of these pipes.

Perfect fit. Removing the old pipe is a pain. Someone on a forum recommended using one of the arms on a gear puller to get the old, stuck pieces of pipe out of the block. I can attest that this works very well.

I can’t speak to the longevity of this part. The price was right as it is quite a bit cheaper than the other offerings. I can see the fitment and build quality seem to be spot on.

Exactly what I needed and fast. The job was less than enjoyable however the installation of this part was perfect. Rigid and strong. Should last as long as expected.

Fit well but do both and make sure the bores are clean, you don't wan't to do this twice, ask me how I know.
