OEM SYSTEM REMOVAL
1. Take off the OE air filter cover by removing the 5/16” x 1/2” OE button head cap screw in the center.
Set the air filter cover and the screw aside for re-use. On some models the cap screw may be covered
by a vanity cover. Carefully pull this cover off that is held on by velcrow.
2. This will expose the filter element, which is then removed by taking out the three Torx head cap screws.
3. Remove the breather hoses from the cylinder head breather bolts by gently pulling on them.
4. Now remove the backing plate and gasket by unbolting the cylinder head breather bolts. Be sure that
the surface is clean and dry.
V&H AIR INTAKE INSTALLATION
1. For a clear understanding of this installation, it is best to refer to the exploded view diagram while
reading these instructions.
2. When installing or servicing the air cleaner, apply Loctite 243 (blue) to the threads of all the fasteners.
3. Install the two cylinder head breather bolts (11). NOTE: Tighten the cylinder head breather bolts to 120-
144 in-lbs (13.6-16.3 Nm).
4. Install the rear and front breather hoses (9) & (10) through the top two holes in the venturi backing
plate (4) aligned as shown.
5. Using the three 1/4”-20 x 3/4” hex bolts (6) sandwich the venturi plate(4), backing plate stiffener (7) ,
the gasket (8), and install onto the throttle body. Make sure the inside edges of all of these parts are
aligned before tightening to 55-60 in- lbs (6.2-6.8 Nm).
6. Install the air filter cage (2) onto the air filter (3) with the 1/4-20 button head cap screws (1). NOTE:
Make sure to orient the air filter so that the metal fin is hidden behind the spoke of the air filter cover.
7. After 100 miles check to be sure that all bolts are still tight. Periodically ensure that these screws remain
tight.
