Manifold

The LSXHR™ 103mm Intake Manifold for LS3 Rectangular Port Applications is the industry's first polymer tunnel ram-style intake manifold and is ideal for generating maximum power in boosted and naturally aspirated engines.

The LSXHR™ 103mm Intake Manifold for LS3 Rectangular Port Applications features:

  • Standard "tall" stacks are interchangeable with separately purchased "medium" and "short" stacks to find the most powerful combination
  • Polymer construction is lightweight and high strength to eliminate power-robbing heat soak commonly found in aluminium intake manifolds
  • 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
  • EGR: No
  • Injectors Included: No
  • Multi-Port Fuel Rails Included: Yes

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.
