The ultimate K04 killer — the Kinugawa Ball Bearing TD05H-16K combines the point-milled 16KX billet compressor wheel with STS Advanced ceramic dual ball bearing technology for the sharpest throttle response and highest power ceiling in the drop-in Mazdaspeed lineup. Up to 450 WHP on a healthy engine. Ball bearing precision improves boost build time by 10–15% over journal bearing variants. Direct drop-in replacement for the factory K04.
APPLICATION
- Fits 2007–2013 Mazdaspeed 3 / Mazdaspeed 6 / CX-7 / CX-9 with K0422-881, K0422-882, K0422-883, K04-581, 582, 583 turbochargers
- Also fits: Mazda6 MPS / Atenza MPS, Mazda CX-7, Mazda3 MPS / Axela MPS, Mazda MPV (JDM)
Maximum power figures are based on compressor map choke flow (total turbo capability / flywheel potential). Actual results depend on vehicle modifications and tuning.
