Roadster NA8CE 1800cc OER 45mm 4-Throttle Sport Injection Kit, No Sub-CPU

This is an OER-brand 45mm individual throttle body (ITB) sport injection kit built specifically for the Mazda Roadster (Miata) NA8CE 1800cc. The kit includes two 45mm throttle body units, the intake manifold assembly, four 50mm air funnels, an idle-up parts set, and a dedicated throttle position sensor. Mounting pitch matches OER, Solex, and Weber sidedraft patterns. The design uses a center return spring layout said to improve left/right balance and resist spring breakage at high RPM. This particular version is the lower-cost variant that omits OER's dedicated D-Jetro sub-CPU controller, making it suited to buyers running a Freedom CPU or an aftermarket full/sub ECU setup rather than the factory-style controller. A separate full-version kit with the sub-CPU included is sold by the same seller.

Listed as unused/new. No flaws or defects are mentioned by the seller.
