The new 911 GT3 is equipped with a variable intake manifold with two resonance valves. This system works in conjunction with the sport exhaust system, featuring two central tailpipes, to achieve optimum cylinder charging and throughput rates.

In addition to a conventional distributor pipe, the new 911 GT3 has two resonance pipes with resonance valves. At low engine speeds both resonance valves are closed. At medium rpm, the first, smaller valve opens. At high rpm, both valves open. The system uses the vibrations in the air caused by the movement of the engine valves to force air into the cylinders.

The result: higher levels of power and torque over a wider engine speed range.
