General Information

in the air and supplies clean air into the engine. The air
filter is directly related to engine lifetime, emissions, and
engine output. Please periodically check, clean, and
replace the air filter.

that the fastening elements securing the air cleaner to
the intake manifold seal the connection tightly.
