The BBK Power-Plus Twin 52mm throttle body is a direct-fit replacement for select 1985–1988 GM 305/350 engines, engineered to improve airflow and throttle response. BBK notes up to 30% increased airflow versus many factory units; each throttle body is CNC-machined from 356 aluminum, includes required gaskets and hardware, and installs without requiring an ECU tune.
