Maruha Individual Throttle Body (ITB) Full Kit · NA6 Miata B6 1.6L

Maruha's ITB kit for the 1.6L NA6 Miata — engineered for the B6ZE engine's specific intake geometry and fuel delivery requirements. Individual throttle bodies per cylinder deliver the throttle response, top-end rev capability, and intake soundtrack that the NA6 deserves. Maruha has validated this kit on their own dyno engines through years of B6 development work.

Specifications:

• Individual throttle body per cylinder — eliminates single-body plenum lag

• Designed and validated specifically for NA6 B6ZE 1.6L engine

• Includes velocity stacks, linkage, fuel delivery adaptation, and installation hardware

• Requires ECU re-tune — Maruha recommends Freedom ECU or equivalent standalone management

Fitment: NA6 Miata 1990–1993 · 1.6L B6ZE engine.
