Cosworth High Volume Intake Manifold for 2004-16 Subaru STI (Throttle by Wire)
Usually Ships in 1 to 2 Weeks
Cosworth High Volume Intake Manifold for 2004-16 Subaru STI (Throttle by Wire). The Cosworth Subaru High Volume Inlet Manifold is cast from aluminum featuring large tapered runners with radiused inlets for improved air flow. Plenum volume has been substantially increased and tuned for power. Engineered for easy installation and is the key to making big power.
Cosworth intake manifold flows an average of 478.5 CFM per runner and the stock manifold flows an average of 421.25 CFM per runner. That is about a 13.5% increase over stock. These numbers were measured at 50 inH2O on our flow bench (some people use 28 inches to measure, but 50 inch is a motorsport standard.
The Cosworth manifold made 12-15 hp above 6000 rpm with no sacrifices in response or low end torque on a stock 300hp engine. Same boost level.As boost levels are increased over stock levels, the power gains compared to the stock manifold will be even higher
