CVT Airbox cover on a manual car - Advice please?

[Sterling]

HEY!

Recently I came across an air filter box cover for the Micra. I notice the difference between the air box cover on my manual Micra and the CVT (auto) Micra is the CVT air box cover has a small add-on to it. This is what the cover on an air filter box on the CVT Micra looks like:

Here is a normal cover for a manual transmission car:

As you can probably see, the air filter box cover in the first picture has a small added-on bit to it. Anyone know what its for? And would it make any difference fitting it to a manual car? I can't honestly see how it would.

Thanks,

Sterling - The Rover kind...

Yup. mine has it as well. Had a good look, its a solid chamber, one way in and out. Does not seem to serve any purpose!
but probably does, in a very miniscule way - strange one.

Probably to quieten the intake noise a bit, what with CVT's droning a fair bit.

Cheers lads. I might just wang it on and see what happens. I can't see it making much, if any difference, but its whats there so I'll use it.
