WARNING!
The air induction system (air cleaner, hoses,
etc.) can provide a measure of protection in
the case of engine backfire. Do not remove
the air induction system (air cleaner, hoses,
etc.) unless such removal is necessary for
repair or maintenance. Make sure that no
one is near the engine compartment before
starting the vehicle with the air induction sys -
tem (air cleaner, hoses, etc.) removed. Failure
to do so can result in serious personal injury.
CAUTION!

All air entering the engine intake must be
filtered. The abrasive particles in unfiltered
air will cause rapid wear to engine compo -
nents.

Many aftermarket performance air filter
elements do not adequately filter the air
entering the engine. Use of such filters can
severely damage your engine.
