Description The L15B Oil Cooler Port Fitting Kit includes a special galley plug, an o-ring, and two -10 male flare port fittings so you can convert the normally bypassed passage to a forced passage to an aftermarket oil cooler. NOTE: Only order if you already own the L15B water pump housing delete. If you try to use the pre-machined ports on the water pump delete plate without the proprietary plug, oil will bypass the oil cooler.
