Improved Racing's EFR-800 silicone radiator hose is a direct fit for the 4.6 liter Mod Motor Ford Mustang GT (SN95 1996-2004) with an aftermarket oil filter relocation adapter block such as the Improved Racing EFR-100, MMR oil filter adapter, Moroso oil filter adapter, or Ford Performance oil filter adapter.

This is the only direct-fit, no hassle solution for this application on the market! Improved Racing's radiator hose connects the factory radiator and coolant expansion tank directly to aftermarket oil filter adapters with a 1.75" water neck (hose barb adapter is also available separately, see part number OB-16-28). This hose also comes with a lifetime warranty, so it's the last radiator hose you'll ever have to buy for this car.

This radiator hose is also available as an add-on for Improved Racing's EFR-100 oil filter adapter block.
