Our Policies


There are no guarantees in high performance engine parts. Our products are engineered to be utilized in high performance engines and may or may not be subject to the demands of racing. Regardless, all components are not warranted unless otherwise stated. Therefore, no warranty or guarantee is expressed or implied. High Flow Dynamics will not be liable for any loss or damage resulting from our products, nor will High Flow Dynamics be liable for any injury or casualty–direct or indirect–arising from the proper use of, or inability to determine the use of, any product we offer. Before using, the end user shall determine the suitability of the product for its intended application, and the user shall assume all responsibility and risk with its use.
