Fit For MR2 Turbo SW20 Celica All-Trac 1989-1995 ST185 3S-GTE 3SGTE Aluminum Intercooler Compatible/Replacement. 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. Provides a denser air charge to each cylinder, directly translating into higher torque and horsepower figures. Minimizes pressure drop across the cooling system while maximizing heat transfer for reliable performance., Manufacturer: HAEDGUO
