Fit For 987 997 99710603702 One Intercooler Tank. By significantly lowering the temperature of air compressed by the turbocharger, the intercooler increases its density, allowing more oxygen to enter the cylinders for combustion. The presence of an intercooler effectively prevents engine knocking or detonation, which safeguards critical internal components from potential damage under high boost. Compact layout allows flexible installation in limited engine bay space without interfering with other components. Lightweight aluminum construction reduces vehicle weight, further enhancing fuel economy and dynamic performance., Manufacturer: HYDBCNP
