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 True Flow's foam, high flow, lifetime filters. Finally, they eliminate the factory air tube, which can have restrictive mufflers or resonators and replace them with their high flow, powder coated mandrel tubes and reinforced silicone couplers to maximize velocity. True Flow kits are easy to install and maintain. No modifications are needed, and all factory breathers, sensors and hoses are left intact. 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. 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. 

Improve your performance and fuel mileage with a True Flow cold air intake system! If you have a diesel with performance modifications, the True Flow XDI system will allow you to get the most horsepower and torque from your engine.
