S-B-Sierra-1500-Cold-Air-Intake-image

Product Information

The product is an intake kit with the part number 75-5137 / 75-5137D. It is designed for Chevrolet and GMC Silverado/Sierra 1500 vehicles with a 3.0L Duramax engine. The kit is intended for use in the year 2020-21.

Before installation, it is important to note that the intake kit may not fit with aftermarket parts such as body lift or lowering kits or custom hoods.

Tools required for installation include wrenches of sizes 7mm, 10mm, and 13mm, a nut driver or flat blade screwdriver, a pin removal tool or flat blade screwdriver, T15 and T20 Torx bits, a Phillips screwdriver, a 5/32 or 4mm Allen wrench, and pliers or a similar tool. It is recommended to use a topside engine creeper for ease of installation.

The kit includes a cotton cleanable filter (KF-1077) or a dry extendable filter (KF-1077D). The cotton cleanable filter is pre-oiled from the factory and requires specific oil amount for cleaning. The dry extendable filter is disposable and does not require oil.

The approximate installation time for the kit is 2 hours and 00 minutes.

It is important to note that the CARB status of the product is pending, and it may not be legal for use in California and other states adopting California emissions standards.

Product Usage Instructions

Before starting the installation process, read the entire product guide.
Ensure that all parts are present. If any components are missing, contact customer support at 909-947-0015.
Do not work on the vehicle while the engine is hot. Make sure the engine is turned off and the vehicle is in Park or the Parking Brake is set.
If using the cotton cleanable filter (KF-1077), refer to the provided guide for the exact amount of oil required for cleaning.
In heavy snowfall or extreme rain conditions, check for accumulated snow and water on the air filter following the original equipment manufacturer’s recommendations for driving in these conditions.
The intake kit includes a plug to seal off the air box opening.
For optimal performance, it is recommended to use the intake without the end cap unless in conditions of extreme heatwave.
To prevent a warning light from displaying, the Air Filter Life system needs to be disabled. Navigate to the Options section of the Driver Information Center and select the Info Page Options.

STOP! IMPORTANT INFORMATION

Warning: Failure to disable the Air Filter Life System will cause a warning light that can only be reset by a GM Dealer. Please ensure you have disabled the system prior to driving the vehicle with your new S&B Intake. Please refer to steps 1-5 to cover this procedure.

Before You Install

We recently discovered that some 75-5137/D kits may be missing the MAF Extension Harness [AI2293-00]. Before installing, please check that you have the AI2293-00 included with your kit. If you are missing this harness please give us a call at 909-947-0015. We apologize in advance for the inconvenience this has caused you. Thank you.

Operation in Snow and Rain

If you are driving in heavy snowfall or extreme rain conditions, you should always check for accumulated snow and water on the air ﬁlter following your OE recommendations for driving in these conditions.
The following is recommended after operating the vehicle up to 100 miles in heavy snowfall or extreme rain: At the earliest opportunity, open the hood and check the air box and ﬁlter. If any snow has accumulated, make sure to remove the snow from the ﬁlter, box, and inlet. It is okay if the ﬁlter is a little wet. Wet ﬁlters will normally dry out on their own. If the ﬁlter is dripping wet, it should be replaced with another ﬁlter that is not wet. Do not reuse the dripping wet ﬁlter until it has naturally dried.

Air Box Plug Testing

Stock intake 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, 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 heatwave.

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.

Emission Standard

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. Check the status of the exemption process by looking up a speciﬁc part number at www.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 but the product has been submitted. Products that have not been issued an E.O. 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.
