FAST 146204 LSXHR 103mm Tunnel Ram Intake Manifold LS7 Raised Rectangular Port

The FAST 146204 LSXHR FAST-RAM intake manifold is the industry's first polymer tunnel ram-style intake designed for raised rectangular port LS7 engines. Engineered for both boosted and naturally aspirated applications, this high-performance manifold delivers exceptional power gains across the RPM range.

Key Features:

• Removable Stack System: Interchangeable stacks of various lengths allow racers to tune and optimize power output for their specific application
• Polymer Construction: Lightweight, high-strength material virtually eliminates heat soak that robs power from aluminum manifolds
• Proven Performance: Testing shows an average 30-horsepower gain between 5,000-7,500 RPM compared to competitor tunnel ram intakes
• Boosted Application Ready: Rated for up to 45 psi of continuous boost pressure
• 103mm Throttle Body Opening: Can be port matched to 105mm for maximum airflow
• Optimized Fuel Delivery: Compound fuel injector angle aims spray pattern for ideal atomization and superior drivability
• Reversible Top Plate: Allows forward-facing or firewall-facing throttle body installation configurations
• Nitrous Ready: Two nitrous nozzle bosses per runner for clean direct port system installations

This manifold is specifically designed for raised rectangular port LS7 cylinder heads and represents the cutting edge in intake manifold technology for serious racers and performance enthusiasts seeking maximum power output.
