Skunk2's Alpha titanium retainers cut valvetrain mass on the Honda/Acura B-series VTEC head, freeing horsepower and improving valvetrain stability at high rpm. Radius-cut edges add rocker arm clearance, while lightening grooves and a reduced overall height trim weight and improve valve seal clearance. Each retainer is CNC machined from certified titanium, individually inspected, and serialized.
