It looks like my air-box too.


interesting, yours is a C4S, but I think 4S and the C2/4 uses the same engine and airbox or?

Or is this airbox from >MY02 3.6L?

I have to check mine (3.4L) at home, have that already dismounted.

haven't got around looking at my airbox from 3.4L but I have some thoughts though:

ain't the holes letting lots of hot air into the engine?

I know from my engine now when we have +20° outside temp. in the engine compartment is enormous heat!

With hot air, bad performance so I'v heard.

The base of the 996 airbox will need some way to drain fluids that enter the intake chute (washing the car, driving in heavy rain, etc...).

Sound may be enhanced with increased perforations, but I wonder about the impact of hot engine air entering the airbox and affecting engine performance.
