While high-performance air intake systems are not exactly new to the market, True Flow has taken a unique approach by replacing restrictive factory components with performance-oriented parts 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 high flow, lifetime Foam Air Filters. Next 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. Easy to install and maintain. No modifications are needed, and all factory breathers, sensors and hoses are left intact.
