adapter. In some applications where the frame or exhaust system interferes
with the new filter depth we recommend using a shorter filter length.
See chart below for possible filter options.

SELECTING COMPONENTS
The components supplied in this kit are for multiple applications. Some
components will not be used for your specific application. To easily select
the correct components for your application, follow the steps below. Then
proceed to the SANDWICH ADAPTER INSTALLATION section.
1. Remove the factory oil filter from the vehicle.
2. Using a rag, clean the oil filter landing on the engine.
3. Take the supplied Sandwich Adapter and hold it up the oil filter landing
on the engine block. The casting needs to seat directly onto the landing
without obstruction. (See Diagram #2)
(See Diagram #1)
1. Using the 5 supplied Sleeve Nuts, try and screw each Sleeve Nut onto
the filter nipple on the engine block until the correct size will completely
thread onto the nipple. Once you have located the correct Sleeve Nut,
disregard the remaining 4 Sleeve Nuts.
