The Aeroflow Performance universal billet sandwich adapter is designed to sit in-between the standard oil filter and the vehicle engine block. It is required for most engine oil cooler installations to provide oil flow to the external oil cooler. In most cases, the factory OE oil filter will work with this sandwich adaptor. It is designed as a universal fitment item and may or may not fit your application.

The main body is made from billet 6061 aluminium, then anodised black for great looks and corrosion resistance. It features two labelled inlet and outlet -8AN ORB ports provided for plumbing the engine oil to and from the sandwich adapter.

The oil filter landing will take oil filter O-ring sizes from inner diameter of 62mm (2-7/16”) to outer diameter 87mm (3-3/8”).  In some applications, when fitting this sandwich adaptor, it may interfere with the frame or exhaust systems, and a new, shorter depth filter may need to be used for ground clearance.
