S&B Cold Air Intake System for the 2020-2021 Chevy / GMC Duramax Diesel L5P. The S&B intake is the best intake system available on the market. We have tested, sold and installed nearly every cold air intake available. After extensive research we have decided to sell S&B exclusively. S&B offers two filter types. Oil based cleanable or dry disposable. Since your not sacrificing performance with either option, the decision comes down to; would you rather clean your filter or throw it away. We prefer the oil based cleanable filter. S&B doesn’t advertise horsepower figures, but from from our experience on the dyno we’ve seen gains of 20 horsepower & 30lbs. feet of torque. Increased airflow over stock results in a 1-2mpg fuel mileage increase, improved drive-ability, quicker turbo response and higher boost pressure. When towing expect to see reduced EGT’s (exhaust gas temperatures). Everything needed for a complete install is included. Installation takes approx. 1hr with basic hand tools. Made in the USA with a lifetime warranty.
