True Flow Air Filter
- True Flow air filters utilize dense foam instead of cotton or paper to give better filtration and higher air flow
- By using the factory air box, True Flow cold air intakes offer your engine better protection from water ingestion
- Foam combined with a sticky emulsion helps the True Flow air filter trap more dirt while allowing air to pass through
- Why keep the factory airbox? Because True Flow intakes are designed to provide better performance with the safety of a stock airbox installation
True Flow Air Filter
Do you ever wonder why your car uses a paper air filter instead of a foam filter like your lawnmower or motorcycle? So did the folks who designed the True Flow air filter. They realized that foam traps far more dirt than paper, and retains better flow characteristics in the process. Thus began the development of the True Flow air filter, a reticulated foam air filter for automotive applications. The True Flow air filter uses millions of tiny air cells in the foam, coupled with an emulsion product, to make it nearly impossible for dirt to pass through to your intake. Your engine stays cleaner with a True Flow air filter, which means you get better mileage and longer life from your vehicle. If that’s where the story stopped, the True Flow air filter would still be a wise investment, but there’s more. The True Flow air filter also provides higher flow than even cotton and gauze performance filters. No matter how good the gauze is, dirt buildup still begins to restrict airflow almost as soon as you fire up your engine. The thickness of the True Flow air filter means there’s far more surface area through which the air can pass even while it’s giving up its dust and dirt to the filter media. Clean air simply flows around the trapped dirt in a True Flow air filter, then continues into your engine to provide peak power even after thousands of miles of use. When your True Flow air filter finally gets too dirty, you simply remove it and wash it out, and you’re ready to roll again. Protect your engine and protect your reputation on the track at the same time by installing a replacement True Flow air filter on your vehicle today.
True Flow Filter
The first question most folks ask when they see a True Flow filter for the first time is “why foam?” The answer is simple: A foam True Flow filter traps more dirt while allowing more clean air to reach the intake manifold of your vehicle. The end result is more power and torque along with a cleaner, longer-lived engine. If those aren’t good enough reasons to invest in a True Flow filter, then we don’t know what are. The True Flow filter works on the same principle as your lawnmower air filter. Lawnmowers operate in extremely dusty conditions, requiring an air filter that could move lots of air even while it was stopping lots of dust. The foam filter element is perfect for such a taxing environment. Since a car engine uses much more air, the True Flow filter uses a much thicker foam than a lawnmower filter, with millions of filtration pockets. When combined with the special tackifier liquid, the True Flow filter can trap an amazing amount of debris while still giving air a pathway into your engine. Your True Flow filter won’t void your factory warranty, and it simply replaces your factory stock air filter—there are no hoses to change or wires to run. So what do you have to lose? Performance and engine life, that’s what. Install a True Flow filter and get both back now.
True Flow Cold Air Intake
It seems like every company in the automotive aftermarket is sticking a conical air filter on a silver tube and calling it the “greatest innovation in the history of induction systems.” In truth, many of these systems do little for power enhancement, and can actually harm your engine by allowing water to enter. That’s why the True Flow cold air intake is so unique. Instead of placing the air filter outside of an airbox structure where it can ingest hot air and moisture, the True Flow cold air intake utilizes the protective factory airbox that came with your vehicle. The factory airbox does a great job of isolating the True Flow cold air intake filter from the elements and also insulating it from engine heat so you get a denser intake charge. From there, the True Flow cold air intake does away with restrictive convoluted intake ductwork, instead adding a smooth tube with silicone connectors. Again, this keeps the cool intake air insulated from the hot engine components, yet also allows for flexibility and long life. A True Flow cold air intake keeps all your stock sensors and engine management equipment in place where it belongs, so you don’t have to recalibrate fuel injection settings or worry about rerouting gear. You just get a premium True Flow cold air intake that can help your car do what you want it to do: Go faster for longer, and do it for less.
True Flow Intakes
There’s a dirty little secret you need to know about most cold air intakes: Their design helps improve engine airflow, but they can also ingest moisture that can damage your engine. That’s why True Flow intakes came on the scene. The engineers involved with True Flow intakes realized that water ingestion was a very real problem for cold air induction systems, but it didn’t have to be. Most intakes do away with the factory airbox in the process of improving airflow, but True Flow intakes leave it in place. Why? Because the designers found that the factory airbox served to keep the air cooler and protect the engine from dangerous moisture ingestion. The airflow restrictions were in the intake duct, not the airbox. So True Flow intakes incorporate a high flow air filter in the factory airbox and vastly improve the remaining ductwork to promote exceptional flow and insulation from heat. The end result is a quiet, safe cold air intake system that builds just as much horsepower (and in some cases more) than the competition. Why would you risk engine damage when True Flow intakes can provide all the performance benefits with none of the risks? The answer is, you wouldn’t.
