Replace heat with horsepower. Garrett’s all-new performance intercooler for S55-equipped cars boasts a 47% larger core with dual pass coolant flow to help reduce intake manifold temperatures by an average of 10°F. Garrett’s S55 cooler is an air-to-water design with CFD optimized, cast aluminum end tanks to improve air flow through its more voluminous core.
This plug and play solution offers an average gain of 12.4 horsepower and 4.9 lb-ft of torque, but that’s really only half of the benefit. Under load, it’s not uncommon to see horsepower figures drop over time as the engine loses its battle with heat—the Garrett intercooler’s party piece is a testament to its achievements in cooling and ensures their advertised power bump is a sustainable one.
As you’d expect from a name like Garrett, this S55 intercooler is also quite heavily over-engineered—this piece was built to cope with nearly four-figure horsepower numbers without blinking an eye.
