Removing and Installing Secondary Air Filter
Replace the secondary air filter (A) every year or after every
third primary filter change (even if it appears clean).
If you're changing the secondary air filter because it is dirty,
inspect the primary filter and the filter canister to determine
the reason for contamination.
• Examine the filter canister for cracks and replace if
necessary.
• Ensure filter sealing surfaces are soft, flexible, and
sealing properly. Hard seals may allow debris through
to the secondary filter.
• Ensure canister retaining latches are secure.
NOTE:
• Do NOT remove the secondary filter element unless it
needs replacing.
• Do NOT attempt to clean the secondary element (A).
Replace only.

IMPORTANT:
When replacing secondary filter, reinsert new filter as soon
as possible to prevent dirt from entering engine intake.

the canister.

If replacing filter, refer to
