Intercoolers are made with high quality aluminum materials and are designed to offer the best performance results yet still maintaining low competitive prices. Our intercooler are fully tested using superflow's industry leading SF1020 flowbench. Our turbo kits using the same intercoolers are also tested with superflow's SF-Powermark engine dynamometer.

Our intercoolers are fully tested and track proven. See below for photos and video of the flowbench test.

Our flowbench tests are done with industry standard at 28 inch of H2O and also higher pressure. Intercoolers are normally used for boosted applications which flow at higher flow rates. However, many intercooler manufacturers/sellers list flowrates that inaccurate and stating a flow rate without even indicating the test pressure is misleading.
