Acoustic valve?

[clio182dave]

Hi can anyone tell me what is meant by removing the acoustic valve? What are the advantages and gains? And how its done? Have seen this a mod that some tuners include and am fairly competent with mechanics and i am also booked in for a map next week so thought i may as well have a go. Car is a 182 by the way. Thanks

gives a little more noise, tiny weight loss.. not many other advantage really...?

obviously only extra noise if you are using std air box with panel filter or normal filter.. independant induction kits would not use this valve.. altho I may be wrong?

maybe clearing some room for custom cold air feeds..

it costs nothing to do it, remove it, decide for yourself and refit if necessary.

its behind the passengers side headlight pretty much,a rubber tube ran off the plenum creating the vacuum,its stops induction noise apparently,part of the cold air feed to the std air box,just remove it,monk you see monk you do,and as said really decide if it makes a difference for you,i never noticed a change

So its the induction pipe leading to the air box?

Its built into the cold air feed yeh.

Thanks, thought this might aid performance but sounds like its just to do with noise lol
