koxuyim Expansion Tank Coolant Radiator Hose Kit compatible with BMW 323 325 328 330 (New 7 Pcs Set )

Quality is okay you do need to sand/trim extruded plastic from the olastic pipe and hose ends to not damge o rings. Holds pressure real well liittle expansion heat doesnt affect it yet have had it on a vehicke for over 3000 mikes since instal no leaks no issues.

the o rings broke apart after trying to install. they were a bit too big but that's what they gave me. went to an O' O' O',O'Reillys and got a size 6. was very snug but worked. haven't finished putting everything back together. Will try to remember to update when I do.

Some of the hoses were out of tolerance, I took the intake manifold off to replace hose and put everything back together and there was a bad leak from brand new hose at the connection. It was very time consuming redoing all of it because of one bad hose. Make sure you refill your system and check the hoses before reinstalling everything. Save yourself some time

Due to location the installing is not easy. Has nothing to do with the product. Works very well

Bmw e46 330xi. Only two of the hoses would fit. bottom left of the radiator and to the bottom of the expansion tank. the top hose was to long. Got these four months ago and both of the hoses are starting to bulge out already. I didn't bother with the hard plastic tubes. Now I'm buying oem hoses. Don't waste your time on these.
