Buy the company that supplies the factories: BorgWarner turbos deliver OEM validation standards with motorsport performance.

BorgWarner's EFR series brought Gamma-Ti turbine wheels and integrated wastegates from top-level motorsport into the aftermarket - technology most turbo brands still chase.

BorgWarner brings more than a century of OE turbocharging heritage to the aftermarket, the same engineering that boosts factory Porsche, BMW, and Audi engines. The EFR line - Engineered For Racing, and the official turbocharger of the IndyCar Series - pairs Gamma-Ti turbine wheels with dual ceramic ball bearings for the fastest spool in the business at 225 to 1,100 horsepower per turbo, while the AirWerks S200, S300, and S400 super-cores deliver brute-force journal-bearing boost all the way to 1,875 horsepower. When your build needs OE-grade quality at race-winning power levels, BorgWarner is the benchmark everyone else gets measured against.
