FAST 146204 LSXHR 103mm Intake Manifold for LS7 Raised Rectangular Ports

• Fuel Rails included

The LSX_HR™ 103mm Intake Manifold for LS7 Raised Rectangular Port Applications is the industry's first polymer tunnel ram-style intake manifold, designed for generating maximum power in boosted and naturally aspirated engines. The FAST LSXHR FAST-RAM Intake Manifold is designed specifically with boosted applications in mind and is rated for up to 45psi of continuous pressure. Compound fuel injector angle aims the spray pattern for ideal atomization, resulting in maximum power production and superior drivability. A reversible top allows for forward- or firewall-facing throttle body installations. The intake manifold also features two nitrous nozzle bosses per runner for clean and easy direct port system installations. Its 103mm throttle body opening can be port matched to 105mm.

The LSXHR™ 103mm Intake Manifold for LS7 Raised 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 aluminum intake manifolds
• Average 30 HP gain between 5,000 and 7,500 RPM over competitors' versions
• 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
