About Garrett:

Garrett was born out of the passion of American founder, John Garrett, for aviation and engineering with the first product, an aircraft intercooler, released in the 1930’s. Turbochargers began rocketing in 1954 and into the auto industry in the 1990’s, when turbochargers went mainstream and global.

With more than 60 years of pioneering turbocharging systems, Garrett Motion is an automotive technology leader in turbochargers and related force induction systems. The company remains American base and is well regarded as one of the best in motorsport turbocharging technology.
