The Aeroflow Performance oil bypass eliminator is designed to eliminate the oil bypass found on Chevrolet engines. It does not allow unfiltered oil back into the engine compared to the factory bypass version, which helps unfiltered oil back into the engine at high pressure. These are a straight-forward bolt-in style that is made from billet aluminium, which is much stronger compared to the failure-prone die-cast piece. A stock-type spin-on oil filter can be used when this part is installed.

This fitting is designed to eliminate the oil bypass found in Chevrolet engines. It also prevents unfiltered oil from spilling back into the engine.
