Air Box Plug Testing

Stock air boxes restrict airflow, so the product is designed with custom air boxes that have secondary and/or enlarged openings. For optimal performance, it is recommended to use the intake without the end cap, except in extreme heat conditions.

Performance Testing

There is no specific information provided about performance testing.

Product Usage Instructions

Step 1: Disconnect Battery

Switch off the ignition and set the parking brake. Disconnect the negative battery cables on both batteries. It is important to disconnect the battery for a minimum of 2 hours to prevent the Check Engine Light from illuminating after installation. Use a 10mm socket/wrench for this step.

Step 2: Disconnect Electrical Harness

Disengage the red locking clip, press down on the tab, and then pull out to disconnect the electrical harness from the MAF sensor.

Step 3: Remove Stock Resonator

Remove the nut securing the stock resonator using a 13mm socket/wrench.

Step 4: Remove Resonator and Intake Tube

Loosen the hose clamp at the resonator and remove the resonator from the intake tube using an 8mm socket/wrench. Then, loosen the hose clamp at the turbo inlet and intake box, and remove the intake tube from the vehicle using an 8mm socket/wrench.

Air Box Plug Testing

Stock air boxes are a signiﬁcant contributor to poor airﬂow 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. For optimal performance, we recommend that the intake be used without the end cap except in conditions of extreme heat.

Performance Testing

After your installation is complete 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.

Warning!
If your vehicle has a Vehicle Emission Control Information decal aﬃxed to the factory airbox, a new replacement label must be obtained and installed in a readily visible position in the engine compartment in order to remain CARB compliant. Failure to do so will prevent the vehicle from passing a smog check. Replacement labels can be ordered from your local dealership. Regulations state that the VECI label shall not be aﬃxed to any equipment which is easily detached from the vehicle. Label placement, under the hood on a painted surface, is recommended.
