Hello,

 

I wanted to install inox test pipe but there is no place to put that strange hose that is fit on stock test pipe. I think that hose come from AIV.

What's happen if I disconnect them?

 

Thank you

nothing, you might aswell remove them

Yep if your cats have been removed then you might aswell dump the AIV's too.

ok cool,

 

it just because I wondering what is there fonction??

But if I ca remove them, that good.

Remove them or simply plug up the holes with a rubber bung or something. Most AIVs nowdays are 10-15 years old, the one way valve inside them tends to leak after this long period. If you just leave the black rubber pipes hanging in mid air, you could potentaily loose manifold pressure. I find the best and quickest way to bypass them is to block up the smaller hoses inside the engine bay, one each side running to each AIV. This way you can get away with not plugging up the larger pipes underneth.

 

BTW The AIVs allow flesh cooler air to pass through the cats, this is only for emmission purposes. Unless your Green, get shut.

lol ok thank for the explication.

 

Could you show me on a picture where are located this two small hose?
