the frame or exhaust system interferes with the new

VERIFYING SLEEVE NUT THREAD SIZE
SANDWICH ADAPTER INSTALLATION
Included in this kit should be a sleeve nut with thread specification as indicated
by the part number purchased and the product packaging. The thread size can
be verified by screwing the male end of the Sleeve Nut into the new or old engine
oil filter. If it is incorrect, please contact your dealer.
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. 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.
