bent, or damaged, replace it.
Note:
Holes in the filter appear as bright spots.
Do not clean the primary filter.
Installing the Filters

To prevent engine damage, always
operate the engine with both air filters and the

Do not use a damaged filter.
2. If you are replacing the inner filter, carefully slide
it into the filter body
