An adapter for the M22x1.5 ports found on most universal oil coolers, presenting an AN8 connection for your hose ends. AN8 is the sensible size for smaller-capacity engines, transmission coolers and power steering coolers, where AN10 hose would be needlessly bulky, heavier and harder to route through a tight engine bay. Screw one into each cooler port and the rest of the system plumbs up in standard AN hardware with no adaptors stacked on adaptors. It is also the cheaper way to get a cooler connected when the oil volume simply does not justify a larger line. Step up to the AN10 version for big-capacity or high-oil-flow applications.
