Have you ever wondered why motorcycles and lawnmowers have foam air filters and most cars have paper filters? It is because motorcycles and lawnmowers work in harsher conditions compared to that of a car. These use foam filters because foam traps more dirt than the use paper filter without compromising better airflow. This is the reason that inspired True Flow designers to make a foam filter line of air filters.True Flow's line of air filters are foam filters that are made of reticulated foam that makes use of millions of tiny air cells in the foam, together with an emulsion product, to prevent dirt from getting into your intake system. This speaks of more mileage and a more efficient engine because it works on cleaner air. Unlike cotton and gauze filters, foam allows more air to go into your system. True Flow Air Filter's thick foam and larger surface area can suck up more dirt without clogging up dirt. Another advantage of having a True Flow Air Filter is that you don't have to throw them away when they're already dirty. All you need to do is give them a little rinse and they're good as new.Aside from air filters, True Flow also has its own line of innovative cold air intakes that are a notch above the rest. The True Flow Cold Air Intake is different from other intakes because its cold air intake is located within the factory airbox of your car, not outside of it like other intakes. True Flow's Cold Air Intake is placed inside the airbox, isolating it from all the dirt, moisture and heat in your engine compartment. Because of its isolation, True Flow Cold Air Intake ingests more cold air that causes the engine to have a denser intake charge giving it more power.So if you want to try something different, something far better than what you have been using, opt for the out of the ordinary like True Flow Foam Air Filters and True Flow Sheltered Cold Air Intake.
