EFR Series Turbochargers
What kind of turbocharger would you build for your high-performance car? The engineers in BorgWarner's Advanced Aftermarket Product group created a wish list of every notable design characteristic. They used materials that had never been combined into an aftermarket turbocharger. EFR delivers quick boost response, powerful performance and reliable durability.
- LOW-WEIGHT GAMMA-TI TURBINE WHEELS AND SHAFT ASSEMBLIES FOR QUICK BOOST RESPONSE
- PATENT-PENDING DUAL CERAMIC BALL BEARING CARTRIDGES FOR MORE THRUST CAPACITY, DURABILITY AND TURBINE EFFICIENCY AT LOW EXPANSION RATIOS

- BorgWarner is proud of its long history of pushing the limits of technology
- From the first appearance of forced induction motor vehicles at the Indianapolis Motor Speedway® in 1952 to the Mulsanne Straight of Le Mans and the winding roads of Nürburgring, BorgWarner turbochargers have made their mark. And that legacy of excellence is embedded in every genuine BorgWarner turbocharger that we produce today.
