About This Billet Turbocharger — Mazda 3 / Mazda 6 2.3L (2006–2010)

The BorgWarner K0422 turbocharger — referenced by part numbers 53047109901 (K0422-881) and 53047109882 (K0422-882) — 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 256 horsepower 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
