Measure up 75 mm (3 in) from the bottom of the liner and measure the lip of the liner 20 mm (0.8 in) as seen in the illustration above.
With a 5/16 or 8 mm drill bit, drill two holes though the wheelhouse liner. Remove the wheel liner fasteners and pull the liner back.
Install the new baffle assembly intake air (lower baffle) to the fender with the two push-in fasteners. The arrows in the illustration above point to where
the push-in fasteners will go.
Install the new inner fender air duct by inserting the duct between the inner and outer sheet metal. The duct has a nipple on the side and will snap in place
on the inner sheet metal of the fender.
