The filtered air flow is funneled through a CFD-designed velocity stack minimizing turbulence and through an air flow straightener grid before passing through the mass air flow sensor

Fluidampr Harmonic Crankshaft Balancer FA20 Half Moon STI EJ257 MY04-07 - WithCONTROL TORSIONAL VIBRATION Fluidampr internally balanced viscous harmonic dampers are essential for any high performance engine build. Reduces the risk of crankshaft failure and minimize wear to critical components. Improves engine timing accuracy and unleashes lost torque and horsepower by dampening torsional vibration (crankshaft twisting and unwinding with every power pulse). No more sheared or bulging rubber pulleys. Not only that, but the
