Acoustic Valve?

[MDP91]

Quick question, as ive had a search and can't find much other than a guide on how to remove. What does the acoustic valve do? And what is to be gained from removing it. On a side note, what is my best bet for an air filter set up on a 182? I don't want a stupid cone.

Nothing noticeable in removing it, there is a guide on the trophy forum.

I'm not a member so I can't view it. Just wondered why alot of people seem to remove it? Am I best sticking with my standard setup and get a panel filter or going with the V6 or PH1 172 box setup?

V6 air box with ITG and regular cleaning.

Not much to be gained through breathing mods on clios

Thank you for your help. I'll have a hunt for one I think.

Do people bother with the CAF? I've heard that it makes little difference to the car without it???

Standard box & filter...

a decent panel filter is probably your best bet, unless all you want is loads of noise

Ive just signed up on the Trophy forum and read that if you remove the AV it can cause a slight loss in power because its there to regulate airflow into the engine and its map.

I've removed mine, made no difference at all. On the plus side it's small amount of weight removed....

It's there purely so the car meets EU drive by noise regulations. Bin it off.
