S&B Filters Cotton Filter Cold Air Intake Kits

S&B Filters cotton filter cold air intake kits are designed to improve airflow and bring down the temperature of the air that enters your engine. To achieve more airflow S&B oiled cotton filters are built with four or eight layers (for diesels) of the highest-quality cotton gauze. They use deeper and wider pleats with more pleats per filter. Plus, their manufacturing process yields filters with almost no "bleed", creating a greater open surface area. All of this adds up to more surface area per filter, and that means more airflow with excellent protection. All S&B cotton air filters are washable and reusable and will protect your engine from harmful dirt and debris.

Your rig will not only gain performance, but also a sporty high-tech appearance under the hood. In addition, the filters and couplers are made with silicone rubber, not urethane, to help ensure they won't degrade or crack and can resist temperatures as high as 400 degrees F. These intake kits are simple to install, and the great looking signature clear lid allows visual inspection of your filter at all times. Remember, there are good air intakes ... and then there are the better intakes--demand the better; choose the efficiency and style of S&B Filters cold air intake kits.

Features include:

* Helps balance air/fuel ratios to improve gas mileage
* Specially-crafted cross-linked intake tube minimizes restriction
* Custom air box keeps loose dirt and turbulent under hood air out of your intake
* Custom-made for your specific year, make, and model
* Easy-to-use installation instructions and illustrations

Note: This cold air intake fits the eTorque models.

MAXIMUM PERFORMANCE

Our cold air intake for the 2020-2021 Silverado / Sierra Duramax L5P 6.6L was engineered to minimize air restriction and flow better than stock. This kit comes with a fully enclosed airbox that protects the filter from dirt and keeps out engine heat.

NEW SNAP IN LID DESIGN

Our new snap-In lid design requires no screws to secure it to the box. This makes installation and inspection quick and easy. Our silicone edge trim provides a protective seal against unwanted, power-robbing engine heat and debris. This kit comes with a massive, highly-efficient air filter which results in better performance and protects your engine. Available in either 8-layer Cotton Cleanable or Dry Extendable media.

PREMIUM SILICONE COMPONENTS

The air filter, coupler, lid seal and box plug are all made with silicone. Silicone is a premium rubber that will seal better and last longer. It handles temperatures as high as 400F without cracking or tearing and won't deteriorate over time.

CHOOSE YOUR AIRFLOW

More air equals better performance. The Duramax L5P 6.6L intake features three air inlet points. If you want to customize the amount of air you take in, we provide an optional box plug that can seal off one inlet point.

NO CHECK ENGINE LIGHTS

S&B devotes a huge amount of resources to engineer our intakes that allow your engine to run properly with stock calibration or enhanced tuning. This kit was designed to avoid check engine lights with it's properly mapped Mass Air Flow Sensor.

S&B devotes a huge amount of resources to engineer our intakes that allow your engine to run properly with stock calibration or enhanced tuning. This kit was designed to avoid check engine lights. Featuring an injection Molded MAF (Mass Air Flow) plate and IAT (Intake Air Temperature) that ensures true o-ring seal to the sensor.

RAM AIR SCOOP FITMENT SEALS BETTER THAN STOCK

The factory scoop attachment uses plastic snap in features to secure the scoop to the airbox, which can result in airflow loss. The S&B scoop seal has a rubberized seal fitment that compresses into the stock scoop resulting is less airflow loss.
