Description
Upgrade your heavy-duty diesel performance with the BorgWarner 171702BW AirWerks S400SX4 Turbocharger, the industry-leading drop-in replacement and performance upgrade for the Detroit Diesel Series 60 12.7L engine. This is a 100% brand new, Genuine OEM BorgWarner AirWerks S400SX4 turbocharger and a direct-fit replacement for the Garrett TMF5502 originally equipped on 2000–2008 Detroit Diesel Series 60 12.7L engines rated at 500HP or 550HP — and it’s also commonly used as a performance upgrade on lower-rated Series 60 trucks.
The 171702BW belongs to BorgWarner’s AirWerks line of drop-in performance upgrade turbochargers, engineered to fit like OEM while delivering meaningful performance gains. Key engineering improvements over the stock Garrett unit include:
- Twin hydrodynamic journal bearings for superior reliability and extended service life
- Extended tip technology compressor wheel with a larger inducer to flow more air and produce more power — while maintaining the same outer diameter so your original intake piping connects without modification
- Twin scroll turbine housing with a 96mm turbine wheel to significantly reduce turbo lag
- Band clamp housings replacing bolt-on units for infinite adjustability, making this ideal for custom installations and easier service
- Compressor cover recirculation grooves for added stability and performance across the RPM range
Compatible with 2000–2008 Detroit Diesel Series 60 engines in trucks, Navistar/International Harvester applications, and DDC-MTU Gen Set configurations. Each unit ships with a QR code warning tag directing installers to diagnostic information and boost control system verification resources to help prevent premature turbo damage, and is backed by a full 1-year unlimited mileage warranty.
