Description
See the EFR-100 Configurator to configure your adapter.
Improved Racing’s Ford Modular V8 remote oil filter adapter allows you to relocate your oil filter to a more practical location (most commonly the front bumper) as well as accommodating the optional addition of oil cooler.
This bolt-on adapter replaces the factory oil filter and water inlet manifold. It has two 1/4″ NPT ports (post filter) and one 1/8″ NPT port (pre-filter) for factory sensor, aftermarket sensors or oil line feeds. The front-facing 1/4″ NPT port is directly compatible with the factory oil temp sensor.
The engine oil ports are -10AN O-ring boss ports while the water port is a -16AN O-ring boss port. Factory radiator hoses of 1.5″ and 1.75″ are supported, as well as the option to use a -16AN adapter fitting for the engine’s water inlet. Oil line adapters are available for -8AN, -10AN, and -12AN lines.
This adapter will fit any Ford Modular V8, however applications with a curved water neck on the factory manifold, such as the SN95 1996-2004 Ford Mustang GT, require Improved Racing’s EFR-800 radiator hose. When selecting this optional radiator hose, you must also select the 1.75″ hose barb adapter in the drop down. These two options make this filter relocation adapter a completely bolt on solution for the SN95 1996-2004 Mustang GT. Applications with a straight water neck on the factory manifold may reuse the factory radiator hose with minimal or no trimming required.
Fitment Note: The optional silicone radiator hose may not clear aftermarket turbo headers. A tight radius 90-degree -16AN adapter fitting and a custom radiator line may be required for these applications. We do not currently offer such a fitting.

Applications
- All Ford Modular V8 engines including the 1996-2010 Mustang GT, 1995-2010 F-Series trucks, 1992-2012 Crown Victoria / Mercury Grand Marquis, 1990-2011 Lincoln Towncar, 1996-2014 E-Series vans, 1997-2014 Expedition, 2000-2005 Excursion, 1998-2014 Lincoln Navigator, and others.
- Note: If the water neck on your factory filter mount is curved (1996-2004 SN95 chassis Mustang GT) you must select the optional radiator hose and 1.75″ hose barb adapter for a direct bolt-on installation. 2005-2010 Ford Mustang GT’s may reuse the factory radiator hose but must select the optional 1.5″ hose barb adapter.
- 1996-2002 Cobra and Mach 1 trims require an optional 1.75″ to 1.50″ radiator hose reducer, part number RHR-175-150. The EFR-800 silicone radiator hose may be used but must also be trimmed for these applications.
- Note: 2003-2004 Ford Mustang “Terminator” Cobra will require a custom radiator hose with double 90-degree bends to connect the factory thermostat housing to the EFR-100 adapter.
- In some cases, this adapter can provide enough clearance for forward facing turbo manifolds when used with our EFR-800 silicone radiator hose. The diagram below shows the amount of clearance provided for manifolds and exhaust headers when using EFR-100 with EFR-800:
