      <p>Take a deep breath. The 911 Carrera GTS models are fitted with a variable resonance intake system featuring six switchable, vacuum-controlled valves. </p>
      <p>These valves enable the system to switch between power- and torque-optimised geometries for all six air intake tracts to produce higher torque in the mid-rev range. The improved charging of the combustion chamber is made more efficient by a flow-optimised intake duct. The cooling system has been adapted to the increased engine output.</p>
