Clean up the look of your engine bay and utilize wasted space with a True Focus Fabrication Combo Tank! This tank bolts directly into (3) factory mounting points with the provided hardware and fully replaces the OEM plastic coolant tank.

For gas motor only, has not been tested with Duramax 

The oil catch can features dual internal baffles & stainless mesh for superior oil separation, as well as a quick drain plug that requires no tools to drain. The TFF filter cover is also easily removed for filter replacement and cleaning. Two AN lines can be ran from the back of the tank, around the battery and along the firewall to each valve cover. 

The coolant expansion tank acts as a high fill point for the cooling system. The two factory coolant hoses attach to the barb fittings and the tank is pressurized with a billet aluminum radiator cap.

** Factory air box will not fit with this tank **

Please leave a note on your order if you would like the "TFF" filter cover to be left raw, otherwise it will match the tank color. We are happy to add additional fittings or different sized fittings to this tank if needed. Please contact us before ordering special fittings
