It allows the turbocharger to operate at higher boost pressures safely, thereby unlocking greater potential power output from the engine. This intercooler efficiently lowers the temperature of compressed air from the turbocharger, increasing its density for more powerful and complete combustion in the engine. Its high-performance core design maximizes heat exchange area, allowing for rapid cooling of intake air and reducing the risk of engine knocking., Manufacturer: PUAYWMOZ
