S&B Filters is a manufacturer of cold air intakes, filters and other performance parts, specializing in diesel/gas trucks and SUVs. Holding true to our goal, we engineer intake systems to greatly reduce airflow restriction, while still protecting your engine and test our product against our competitors following ISO 5011 standards. We keep our quality high and our pricing low by making almost everything ourselves in the U.S.
Breathe easy. Your engine and warranty are protected.
A mountain of dust and our 1/2 million dollar lab is how far we've gone to make sure your investment is protected.
Tested to a higher standard.
S&B tests to the internationally accepted ISO 5011 Standard when testing for airflow, efficiency and capacity. This is the same protocol used by most of the large automakers.
Airflow testing shows us how we compare to stock and our competitors. The goal is to beat both.
We test for efficiency to make sure that your engine is protected from debris while sucking in even more air. Lastly, we monitor the capacity of the filter to see how much dirt it can hold before needing to be serviced.
Precision and accuracy.
Our environmental control system is top of the line. S&B strives for accuracy and repeatability. In order to have dependable results, you have to have tight control over the humidity, temperature and barometric pressure.
It's important to know how we stack up against stock and our competitors in order to be the best. We mount each intake system on our test equipment to measure the airflow from zero to the max CFM of the vehicle. We then compare the results and make design changes until we have maximized the airflow while still protecting your engine.
Protect your engine.
While airflow is important, it is equally critical to insure that your investment is protected. To do so, we first determine the max CFM the vehicle will generate at wide open throttle as it is more difficult to stop dust the greater the airflow. We then start pulling this amount of air through the intake while literally shooting fine particles of dust at the filter. Any dust bypassing the filter will be caught in the absolute blanket to determine the efficiency.
Some competitors have testing done at low CFMs in order to show higher efficiency rates, so beware.
We're not kidding.
Our testing is so controlled that we even heat the absolute blankets pre and post testing in order to remove the humidity. The absolute blankets catch any dust that gets past the filter during testing in order to determine the efficiency rate.
Removing the humidity insures that you are only weighing what actually bypassed the filter. Protecting your engine while providing better airflow is our top priority.
