I have an intake manifold and plenum from a 2008 997 GT2. This is an aluminum intake that Porsche made just for the GT2, this would be an upgrade for a 996TT.


Price: $1000

Here is what Porsche tech info said about the intake design:

Expansion intake manifold
More power than a 911 Turbo – from the same flat-six engine. No, it wasn’t easy, which is why it required yet another worldwide innovation.
The air intake manifold on the new 911 GT2 employs a totally new principle unlike anything ever featured on exiting induction systems. Our `expansion’ intake manifolds is a radical new development that is the polar opposite of the resonance principle used on conventional turbocharged engines.
A resonance manifold increases engine output by forcing additional air into the combustion chambers. To do this, the manifold is designed in such a way that the air – which vibrates due to the action of the valves – is in a compression phase as it passes through the inlet ports. Unfortunately, compression not only increases air volume, it also increases air temperature. The result is poorer ignition.
Our new expansion manifold simply turns that principle around. The internal geometry is radically different from that on a resonance intake system. Key modifications include a longer distributor pipe, with a smaller diameter and shorter intake ports.
As a s result, the air is in the expansion phase as it enters the combustion chambers. Since expansion always cools, the air/fuel temperature is lower and ignition is significantly improved – thereby increasing performance.

 

Anything special needed use this on a 996tt?

 

I don't think so.
