Grams NC Miata 70mm Throttle Body

(1 review) Write a Review

The new Grams 70 mm Drive-By-Wire Electronic Throttle Body for MX-5 2.0L NC-Miata is the perfect upgrade for the restrictive factory 65 mm Miata throttle body. The Grams throttle body is a Plug-n-Play direct OEM replacement that doesn’t require wiring or mounting adapters. These units are not remanufactured. Each throttle body includes all new components including a CNC machined billet 6061-T6 aluminum housing with a precision-honed oversized bore, a high-torque servo motor, and a proprietary Non-Contact Hall Effect TPS sensor. To ensure the best performance, throttle response and driveability, each TPS sensor is calibrated to meet the specific requirements of the vehicles engine management system. The Grams electronic throttle body is the perfect upgrade for both modified and stock engines with increased airflow and reliability demands.

· Precision Honed Oversized 70 mm Bore
· CNC machined billet 6061-T6 aluminum housing
· Aluminum Throttle Plate
· Factory Programmable Non-Contact Hall Effect TPS

    Throttle body

    The throttle body is great. It arrived without the spacer and gasket. Once they arrived, installation was easy.
