Yea. That piece to the right is the valve body. Most people here just stick to certain brands/names. Those being LFP and Factory Tech.
But your paying 325 (w/o shipping) for a VB, filter, and a new gasket.
Go through Chikenears.

VB - 225
Filter - 20
Re-use your gasket.
-------------
Total - 245 w/o shipping
Or Upgrade to a 4x4 pan (its bigger) for only 69 bucks w/ a filter.
So... Valve Body 225
4x4 pan and filter 69
