S&B Filters

S&B Filters Cold Air Intakes, Air Filters, Intake Elbows, Body Mounts, Fuel Tanks and More

 

S&B Filters is a manufacturer of cold air intakes, air filters and other performance parts, specializing in diesel and gas trucks and SUVs. S&B Filters designs and engineers intake systems to greatly reduce airflow restriction, while still protecting your engine. S&B Filters continually tests against the competitors following ISO 5011 standards. S&B Filters keeps quality high and pricing low by making almost everything in-house, right here in the U.S. 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 aftermarket competitors. The goal is to beat both. S&B Filters tests for efficiency to make sure that your engine is protected from debris while sucking in even more air. Lastly, S&B Filters monitors the capacity of the filter to see how much dirt it can hold before needing to be serviced.

S&B Filters is constantly testing competitor products in order to be the best. When they make a nice kit, we redesigned S&B’s version and made it better. That is just healthy competition. S&B Filters competitors do not like the fact that these test results are published for public view. Instead of complaining, they should just work harder and try to… Get Better!  It is important to know how S&B Filters stacks up against stock and competitor products to be the best. S&B Filters mounts each intake system onto highly-calibrated test equipment to measure the airflow from zero to the max CFM of the vehicle. S&B Filters then compares the results and make design changes until they have maximized the airflow while still protecting your engine. Currently, S&B Filters offers a wide selection of aftermarket products, including Air Filters, Cold Air Intakes, Air Intake Particle Separators, Helmet Particle Separator. UTV Intake Particle Separators, Silicone Body Mounts, High Capacity Fuel Tanks, Fuel Transfer Pumps, Jeep Hood Scoops, Turbo Screens, MAP Sensor Spacer, Filter Cleaning Kits, Filter Wraps, Intake Elbows, Intake Scoops, Crankcase Breathers, and Silicone Tool Trays

While airflow is important, it is equally critical to ensure 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. S&B Filters testing is so controlled that they 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 ensures that you are only weighing what actually bypassed the filter. Protecting your engine while providing better airflow is top priority.  Accesspeed is proud to offer S&B Filters products to our customers. With our lowest price match guarantee, you will always find the best combination of price and selection at Accesspeed.


Air Intake and Induction » Mass Air Flow Sensors

What is a Mass Air Flow Sensor or MAF?

The mass air flow (MAF) sensor is part of your vehicle's electronic fuel injection system. The MAF sensor calculates the total amount of air entering the engine through the intake tract, and tells the computer how much fuel to inject for air coming through the intake. 

 

 

How does a mass air flow sensor work?

The mass air flow (MAF) sensor has two sensing wires in the housing that protrudes into the intake tube prior to the throttle body.  One wire is heated by electrical current, the other is not heated at all.  As air flows across the heated wire, it cools the wire down. When the temperature difference between the two sensing wires changes, the MAF sensor automatically increases or decreases the current to the heated wire to compensate, telling the computer how much fuel to send through the fuel injectors.

 

How much horsepower and mpg increase can I expect from an aftermarket mass air flow sensor?

Aftermarket performance mass air flow (MAF) sensors replace your OEM sensor and improve on mileage and can increase horsepower by up to 20-HP, depending on the vehicle and engine. Performance MAF sensors increase airflow and low-end torque, without robbing top-end power, and works with factory electronics.

 

What are the symptoms of a bad mass air flow (MAF) sensor?

  • The engine hesitates or drags while under load or idling.
  • During acceleration, you experience hesitation and jerking.
  • The engine coughs, sputters, or hiccups.
  • Excessively rich idling or lean idling.
  • The engine is difficult to start or crank over.
  • The engine stalls or dies shortly after starting.

 

Can you drive with a bad mass air flow sensor?

Yes and no. Yes, you can drive your vehicle with a bad mass air flow (MAF) sensor, but only to get it home or to a repair shop to fix or replace it. Ignoring this problem can lead to far more severe engine problems and damage.

 

Why would a car run better with the mass air flow sensor unplugged?

If your vehicle runs better with your MAF sensor unplugged, you likely have a shorted-out sensor. When the computer does not read a signal from your mass air flow sensor, it provides the computer with a stock signal that will allow you to drive your vehicle for a short period of time to get it fixed or replaced.
