2 1/2” NPT x 1/2” Barb Fittings

In most cases the Factory Oil Filter will work with the supplied sandwich adapter. In some
applications where the frame or exhaust system interferes with the new filter depth we
recommend using a shorter filter length. See the chart below for possible filter options.

SANDWICH ADAPTER INSTALLATION
The Sandwich Adapter fits between the oil filter and the engine block.
Before removing the oil filter, check the clearance between the bottom of
the filter and the closest vehicle obstruction. If there are none, then
proceed with the installation. Otherwise, the Sandwich Adapter is 2-1/4”
Thick, so you will need 2-1/2” more clearance then stock. If you determine
that the stock filter will not fit, refer to the Filter Chart for alternative filter
heights.
1. Remove the factory oil filter from the vehicle.
2. Take the Sandwich Adapter and the two Hose Barb Fittings provided.
Using Teflon Tape or a suitable sealant, screw the Hose Barb Fittings
clockwise into the Sandwich Adapter until snug. (See Diagram #2)
3. Using a wrench tighten the two Hose Barb Fittings.
4. Take the O-ring provided, apply a thin film of oil and install into the
O-ring groove on the Sandwich Adapter. (See Diagram #2)
5. Making sure the engine block filter landing is clean from oil and dirt,
take the Sleeve Nut, Sandwich Adapter, O-ring, and install onto engine
sliding the Sleeve Nut thru the Sandwich Adapter. Turn sleeve nut
clockwise onto the engines filter nipple. (See Diagram #2)
6. Using a torque wrench, torque the Sleeve Nut to 20 ft. lbs.
1. Install both ends of the hose onto the Hose Barb Fittings, forming a loop.
2. Take the looped end and route the hose to the oil cooler making sure to stay clear of sharp objects, exhaust systems, etc.
All bends in hose need to have a minimum radius of 5” or the diameter of a small coffee can.
3. Cut and attach hoses to the oil cooler. Secure hoses using zip ties.
1. Before starting the vehicle, check engine oil level and add accordingly.
2. Always check fluid levels on a flat surface.
3. After installation and vehicle has completely warmed up, recheck fluid level and inspect all connections for leaks.
