Kinugawa Turbo Ball Bearing TD05H-18G for MAZDA Mazdaspeed 3 6 MPS MZR DISI 2.3L CX7 CX9
Faster spool, sharper response, longer service life — the Kinugawa Ball Bearing TD05H-18G is the premium upgrade for Mazdaspeed 3, Mazdaspeed 6, CX-7, and CX-9 MZR DISI 2.3L builders who want more than the journal bearing version. STS Advanced ceramic dual ball bearing technology improves boost build time by 10–15% and delivers improved shaft dynamics for greater durability. Up to 400 WHP on a healthy engine. Direct drop-in replacement for the factory K04.

- Also fits: Mazda6 MPS / Atenza MPS, Mazda CX-7, Mazda3 MPS / Axela MPS, Mazda MPV (JDM)
