FAST LSXHR INTAKE MANIFOLD LS3 103mm KIT Product Description:

Overview

The FAST LSXHR intake manifolds are available for LS3 rectangular port applications, as well as LS7 raised rectangular port applications. These units are the industry's first polymer tunnel ram-style intake manifolds and are ideal for generating maximum power in boosted and naturally aspirated engines. Order the model designed for your application.

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 aluminum intake manifolds.
  • Average 30 hp gain between 5,000 and 7,500 rpm over competitors' high-ram intake manifolds.
  • Rated for up to 45 psi 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.
