Who says you can't have your cake and eat it too? The BBK Dual Stage Intake runner manifold increases high end horsepower without losing low end performance. Today's breed of smaller displacement motors use small diameter, medium length runners to deliver torque, but are lacking in high RPM horsepower. BBK's DSI intake provides the best of both worlds by using extra long small diameter runners for increased low end over stock with short large diameter runners for increased top end performance.

With eight butterflies you can pick the RPM at which they need to transition from the long runners to a combination of long & short runners. The best part is that the entire set up is packaged within the factory parameters so such things as existing throttle body & cold air upgrades will still work with this new manifold.
