Show original supplier description
The Nick Williams 103mm Electronic Drive-by-Wire Throttle Body is precision CNC-machined from billet aluminum in the USA to meet the airflow demands of high-performance LS engines. This redesigned 103mm unit replaces previous 102mm versions and is engineered for increased airflow. Designed for drive-by-wire LS performance engines, this throttle body utilizes a 6-pin late model connector that is compatible with corresponding wiring harnesses. It comes completely assembled with bolts included. However, the larger diameter throttle blade necessitates an aftermarket intake manifold for proper fitment. Installation of this throttle body requires tuning. Additionally, please note that this product is not California C.A.R.B. E.O. Compliant and cannot be shipped to California. It is legal for use on Uncontrolled (Non-Emissions Controlled) Vehicles or Racing Vehicles only.
