Fit my 2008 328i BMW perfectly!
This fit my 328i BMW perfectly! It was easy installing the hose to engine on the top end. Connecting it to the water pump was a challenge, because the hose clamp was turned downward. If not for that, it would have been a breeze. Saved me hundreds of dollars. Buy this one!!

Great product!
Style: Two Pieces
These were a perfect fit for my MB and very easy to install. Great value for the money. They should last given the way they were built.
