Can someone help me what the 2 black pipes that go around the airfilter box are for? Most of the 355 engine bays I see don't have them .... It's a 1996 Manual Spider 2.7 Image Unavailable, Please Login
Those are intake resonators. The question is whether they are designed to reduce the intake noise or to produce extra Oooompf. Image Unavailable, Please Login Image Unavailable, Please Login
Interesting. Non-USA application. Must mean a 2.7 Spider is pretty rare outside the USA? First time for me seeing that configuration in nearly 25 years of 355 observation and 8 years of ownership. Thanks! Sent from my iPhone using Tapatalk
I've also only seen it on my car untill now ... also the "side plates" are different to accomodate the resonators and some mounting parts. I would be very interested to see how many Manual 2.7 Spiders there are in EU-specification ...
Ferrari produced Berlinettas and GTS’s in 1994 and 1995. Spider production didn’t come online until 1995 and U.S market took the large majority of them.
The early F355s had the air inlet at the C-pilar window inlet. Later they moved it in front of the radiator. PERHAPS because the spyder has no C-pillar window.
The intake resonator (the plastic tube around the air filter box) is not related to where the air inlet is. Connection to the air scoop is still done with the flexible duct (#10, same as on the US models). The part #9 is different on the intakes with a resonator - it has two ports, one for the flexible duct and the other for the resonator (#15).

And why (in Europe) reduce the noise of a Ferrari? Perhaps, on a Spider, the resonators were added to "fine tune" the sound to perfection for when you are driving your 355 top-down (when the engine sounds are just behind your head).
