careful not to crimp the filter
element edges between the air filter

properly seated.
6. Replace the air filter housing cover and secure the clamps.
7. Replace the air inlet tube and secure the clamp.
Note: Be sure the hinge features of the air filter cover to the air filter
housing are fully engaged when reassembling the air filter assembly.
Note: Failure to use the correct air filter element may result in severe
engine damage. The customer warranty may be void for any damage to
the engine if the correct air filter element is not used.
