Grams Performance DBW Electronic 70mm Throttle Body 16+ Mazda Miata MX-5 ND

In this kit, you get a Grams Performance 70mm electronic throttle body assembly, designed as a direct replacement for your 2016-2020 Mazda MX-5 Miata. This unit is built to significantly increase airflow compared to the factory 65mm throttle body, which can help your engine breathe better and potentially improve performance. It’s a plug-and-play unit, meaning no extra adapters are needed for installation.

The throttle body itself is CNC machined from a solid piece of 6061-T6 aluminum, giving it a well-built feel. Inside, the bore is precision honed to a full 70mm, and it uses an aluminum throttle plate. For electronic control, it features a high-torque servo motor and a factory-programmable, non-contact Hall effect TPS (Throttle Position Sensor) with an optimized response curve. This setup aims for consistent and accurate throttle input.
