About This Billet Turbocharger — Mazda 3 / Mazda 6 2.3L (2006–2013)
The BorgWarner K0422 turbocharger — referenced by part number 53047109901 (K0422-881 / 882) — is the factory turbo on the Mazda 3 MPS (Mazdaspeed 3) and Mazda 6 MPS (Mazdaspeed 6) with the 2.3L MZR-DISI turbocharged engine, producing 263 horsepower in the Mazdaspeed3 and 274 horsepower in the Mazdaspeed6 in stock form. The K0422 is a capable turbocharger for street use, but the cast aluminum compressor wheel becomes the limiting factor for enthusiasts looking for more power — it restricts airflow at higher boost levels and is vulnerable to damage if boost is significantly elevated.
This billet upgrade replaces the cast OEM compressor wheel with a precision-machined billet wheel while maintaining all factory mounting dimensions and compatibility with stock intercooler, downpipe, and intake connections.
K0422 Billet Wheel Benefits
- Higher flow ceiling — supports power targets beyond what the OEM cast wheel can deliver
- Stronger material — resists compressor surge damage that can crack OEM cast wheels
- Improved efficiency — tighter blade tolerances reduce heat and lag
- Drop-in fit — no modifications to turbo inlet, outlet, or manifold required
