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. By dissipating heat from the intake manifold before the intake air reaches the cylinder, this part notably lessens the strain on the engine's main cooling system., Manufacturer: HUASRCFP
