Hello,
Installing the Mtech kit myself and trying my best to follow guides from Tischer and some post on here. Just by searching and looking at pictures, part #51118044378 is the same for two different parts and I have both. I believe the solid part is the one used for the 335i. But I'm not really sure, or why it would be.

I understand the whole thing about the oil cooler but this is the other side.

Wish there was a more detailed DIY for the Mtech.

Thanks
