Testing and Maintenance
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 will void
your warranty.
Air Box End Cap Testing
Stock air boxes are a significant contributor to poor air flow which is why S&B designs custom air boxes with secondary and/or enlarged openings. With
that said, S&B recognizes the benefits of cooler air, so we have included a plug to seal off the opening if so desired. For optimal performance, we
recommend that the intake be used without the end cap except in conditions of extreme heat.
ISO 5011 Test Data:
With the plug installed, the intake improves airflow by an average of 51.9% versus stock.
Without the plug installed, the improvement increases to an average of 54.2%.
The California Air Resource Board (CARB) requires that an E.O. identification label be applied to the vehicle in order to pass a smog check inspection when a Performance
Intake Kit has been installed. You must place the E.O. label provided on or near the intake kit after installation so that a smog check technician can easily verify the E.O. number.
As of April 2009, S&B has never had a product where CARB denied an exemption request; however, the exemption process with CARB can take as long as 18 months. Check
the status of the exemption process by looking up a specific part number atwww.sbfilters.com. The CARB Exemption number and/or status is listed under the Product Details
section for each part number. If the status shows as “Pending,” CARB has yet to issue an exemption. Products that have not been issued an EO number are street legal in most
states, but may not be used on emission controlled vehicles in the state of California and are for off road use only. If you purchased your kit from S&B Filters directly, we will
automatically mail you your Exemption Sticker when it is issued to us. If you purchased your kit from an authorized S&B Filters Dealer, log onto our web site and register to
receive your Exemption Sticker.
