PERFORMANCE TESTING
∗ Engage parking brake and start your
engine. Listen for abnormal noises. If an
air leak is detected, re-inspect hoses and
connections as they may need to be
repositioned and tightened.
∗ S&B FILTERS recommends that you
keep your OE intake system in the event
it is required in the future.
∗ In order to maintain your warranty, all
connections and components must be
checked periodically for alignment and
for proper tension on all connections.
Failure to do so may void your warranty.
∗ Use only S&B FILTERS cleaning and oil
products to service your filter. Using any
other brand oil and or cleaners on your
S&B air filter may void your warranty.

You must place the E.O. label
provided on or near the intake kit

check technician can easily verify
the E.O. number.
