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.

Range of units supporting 225 to 1,100 horsepower per turbocharger

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.
