Show original supplier description
The Grams Performance 70mm Drive-By-Wire (DBW) Throttle Body offers a direct, plug-n-play replacement for the stock 65mm throttle body in the 2.0L Mazda MX-5 Miata (2006-2015). Constructed from a CNC-machined billet 6061-T6 aluminum housing, the throttle body features a precision-honed 70mm bore and an aluminum throttle plate for optimal performance. It utilizes a high-torque, precision servo motor and a factory-programmable, non-contact Hall Effect TPS sensor, which is calibrated to the vehicle's specific engine management system for improved throttle response and driveability. This unit is not a re-manufactured part and requires no swapping of electric motors, wiring, or mounting adapters for installation. Please note that this throttle body is not CARB approved and cannot be shipped to addresses in California or Colorado.
