A high performance throttle body is a must if you want a throttle response so sharp it will be only second to the reaction of a skilled driver. As the throttle body is a gateway to the engine's power producing cycle, a high performance throttle body not only  allows you to minimize the delay between drivers input and response of the system, but also to extract even more performance out of other engine mods. BLOX Racing billet throttle bodies are designed as a direct replacement and reuse the OEM sensors.  Each billet throttle body is manufactured from precision machined AL6061 alloy. The larger bore sizes provide increased airflow and with the proper intake manifold and camshafts, helps develop additional usable horsepower and torque. Additionally, each throttle body features an IAC port and provisions to adjust idle air and throttle plate stop position.
