The APR Intercooler System dramatically lowers charge air temperature and resists heat soak far better the factory intercooler system. Through a massively increased core volume, superior intercooler core design and smooth, cast end tanks, APR’s engineers were able to create an intercooler capable of supporting power levels well beyond that of the factory unit. Expect increased horsepower and torque and dramatically prolonged performance.
Each unit uses a high quality, bar and plate core with staggered and louvered fins. The Intercooler’s exceptionally tall design and fin structure exposes the core to a greater volume of airflow than possible with the factory or similar aftermarket short and thick core designs. With more of the intercooler directly exposed to the elements, cooling effectiveness dramatically increases.
Internally, the APR Intercooler System features a staggered and louvered fin design with a core density chosen as a balance between cooling effectiveness and pressure drop. Due to the core’s massive volume, the balance was easily adjusted to favor minimal pressure drop while still providing superior effectiveness compared to the stock tube and fin design.
Multi-ply silicone hoses provide an unrestricted path for airflow entering and exiting the intercooler. The hoses are engineered to properly connect the intercooler to the factory charge piping system.
APR’s Easy-Flow Silicone Hose design features stepped mounting surfaces for smooth transitions from one pipe to another. Traditional designs simply sit on top of each other, often resulting in a disruptive airflow path. By using the stepped design, hoses fit properly without airflow restrictions, resulting in the most ideal path for moving air through the intercooler and into the engine.
