Sealed Air Intake Systems by True Flow

When Performance Counts - Ever since the invention of cars, there have been people trying to improve performance. Modifying the air intake system to increase airflow is one way to improve. A properly designed air intake increases the airflow to the engine so that it combusts fuel more effectively. Up until now, replacing the factory air box with an open element air filter system was your only alternative.

Though open element air filter systems are effective for increasing airflow they have a few large flaws. First of all, open element air filters tend to make noise, (this of course is not a drawback to those who subscribe to the louder is better school of driving). Second, air boxes are designed to protect your engine from debris. Open element filter systems expose your filter and your engine to dirt and moisture. Finally, an open element filter is subjected to heat from the engine, creating hot air robbing your engine from oxygen it needs for effective combustion, resulting in a possible power loss.

True Flow air intake systems are a unique departure from traditional air intake systems. The factory air box is left intact keeping the airflow cooler while protecting the filter from debris and moisture. The factory filter is replaced with one of our foam, high flow, lifetime filters. Finally we eliminate the factory air tube, which can have restrictive mufflers or resonators and replace them with our high flow, powder coated mandrel tubes and reinforced silicone couplers to maximize velocity.

True Flow kits are easy to install and maintain. Each kit contains the necessary hardware required to install, (like our custom fiberglass reinforced silicone couplers and stainless steel worm clamps). No modifications are needed, and all factory breathers, sensors and hoses are left intact.

Stop More Dirt & Get Better Airflow - True Flow stops more dirt due to its superior foam technology. Foam has been used for years in off road applications such as motorcycles, ATVs and Off-Road race vehicles. True Flow developed an air filter using fully reticulated foam cells and specially formulated tackifier that create an impossible journey for dirt particles to enter your engine. More dirt in your engine means lower performance, lower gas mileage, and engine wear. See True Flow's legendary performance and protection capabilities by watching the True Flow Air Filter Test. The test proves that True Flow stops more dirt, while performance gauze and paper filters let more dirt get through to your engine.

The EPA has estimated that a dirty filter can cause a 10% decrease in fuel efficiency. Because performance gauze and paper filters are only 1/16 of an inch thick, the minute you start driving they get dirty, start to clog and restrict air flow causing a loss in performance. True Flow doesn't clog because its reticulated foam construction is 16 times thicker than performance gauze or paper. Reticulated foam allows air to flow around the captured dirt. Unlike filters, True Flow provides great air flow even when it gets dirty.

Testimonial - "I have had the True Flow system on my 2001 Toyota 4 Runner for a few months now and the difference over the OEM system is day and night - much better fuel economy and a BIG difference in acceleration. Prior to the True Flow system, I had a K&N drop in filter installed and after a short while I would notice dirt behind the filter on the air box. With the True Flow, there is absolutely no dirt behind the filter whatsoever and used oil analysis performed on this engine have shown very low silicon (dirt) ingestion. Being a mechanic, I was very skeptical at first, but now I am a firm believer in the True Flow system." -Christopher Sideris
