Killer horsepower throughout the useable rpm range! Weiand Street Warrior LS intake manifolds are designed in conjunction with Starr Technologies of Australia. The Street Warrior LS intake manifolds incorporate Formula 1 style trumpet-shaped inlets on each runner and a consistent cross-sectional area to enhance airflow through the port. The latest technology in airflow sciences was used to develop this optimized runner, geometry-based on years of racing and dyno work. The outcome is unbelievable increases in horsepower and torque from 2,000 to 6,200 rpm--power you can feel and use in daily driving, road racing, or drag racing. Testing showed gains of 30+ hp and 30+ lbs./ft. of torque over the popular LS6 intake! Features and benefits include: * One-piece Nylon 6 composite construction for weight savings and heat dissipation * Accept all OEM sensors, lines, and fuel components for an easy bolt-on installation * Open-plenum chamber with no support poles to disturb airflow * New manufacturing technology allows low cost to consumers compared to the competition * Accept LS-2 style 90mm throttle bodies or stock LS1/LS6 throttle bodies with available adapter
