About S&B Filters

Having an inferior or clogged air filter can negatively impact your car’s performance by robbing it of engine power and that is something no driver wants. When deciding to purchase a replacement filter, a cold air intake or other performance part you want a product made by a name you can trust and LMPERFORMANCE wants to do help you do just that by offering you the S&B products.

High quality and low pricing are the consummate goals of S&B and to achieve this they have a manufacturing process that nonpareil with strict testing following ISO 5011 standards with nearly everything being done by S&B in the USA. The company’s objective in the production of cold air intakes, filters and other performance parts is to considerably reduce airflow restriction and at the same time protect your car’s engine.

Recognizing how paramount testing is in designing the ultimate product S&B tests using the internationally accepted ISO 5011 Standard in their testing for airflow, efficiency and capacity and they use these testing results to determine how they compare to stock parts and to the competitor’s parts. The testing protocol includes such things as determining the filter’s efficiency making certain your engine is protected for debris while sucking in more air and monitoring the capacity of the filter to determine how much dirt it can hold before it needs to be serviced.

And S&B Air Filters doesn’t stop there but has established a primo environmental control system affording them the opportunity of having control over humidity, temperature and barometric pressure. To accomplish this goal S&B uses absolute blankets designed to catch any dust that gets past the filter and additionally they heat the absolute blankets pre and post testing in order to remove humidity thus accomplishing the goal of only weighing what actually bypassed the filter.

Unlike some of their competitors who have testing done at low CFMs in order to show higher efficiency rates S&B first determines the maximum CFM a vehicle generates at wide open throttle then they start pulling this amount of air through the intake while shooting fine particles of dust at the filter. Any dust bypassing the filter will be caught in the absolute blanket to determine the efficiency. This is important because it is considerably more difficult to stop dust when there is greater airflow and thus this is a much more reliable testing procedure affording you the guarantee of better protection for your car.

S&B acknowledges the fact that competition is important and they use this knowledge as a motivator to continually improve their products by continually testing the competition’s products and then making theirs better. And S&B is so confident they have a superior product they back S&B air filters and intake kits purchased from Authorized Dealers by S&B’s Million Mile Limited Warranty when used under typical driving conditions and on vehicles for which they were designed. If one of their cold air intakes or performance air filters is not performing properly or is defective, S&B will replace it and you can’t get better than that. If you use an S&B product for (1) any type of racing or competitive event (2) any off-road use, (3) custom or modified product, (4) any industrial or marine applications, and/or (5) any illegal highway use.
