- Average 30 HP gain between 5,000 and 7,500 RPM over competitors' high ram intake manifolds
- Rated for up to 45psi of continuous pressure
- Compound fuel injector angle aims spray pattern for ideal atomization, resulting in maximum power production and superior drivability
- Reversible top allows for forward- or firewall-facing throttle body installations
- Two nitrous nozzle bosses per runner for clean and easy direct port system installations
- 103mm Throttle body opening can be ported to 105mm

Throttle Body
NEW Nick Williams 103mm drive-by-wire CNC billet throttle body for LS applications. This redesigned version replaces the previous 102mm boosted & non-boosted versions.
Nick Williams Performance drive-by-wire throttle bodies are CNC precision-machined from billet aluminium to meet the demands for increased airflow on the drive-by-wire LS performance engines. The 103mm throttle bodies require an aftermarket intake to fit the larger diameter throttle blade. They use a 6-pin late model connector that works with late model wiring harnesses. The Nick Williams Performance drive-by-wire throttle bodies come completely assembled with bolts included.
