what the

[CoasTek240]

ok what is that black box with the stripes on it located to the right of the header?.. i have one in mine.. but there isnt;t one in my boys' s14?

[AKADriver]

It's a resonator box, and it's also the air supply for the AIV.

S14s have no AIV.

[CoasTek240]

my bad here's the picture.. it's the thing right next to the header

[CoasTek240]

hey aka driver.. what's the AIV?

[SupraFreak]

Hey man...

the AIV (Air Induction Valve), an emissions control instrument, lets air into the exhaust manifold that activates the catalytic converter.

I suggest keeping the valve in its place. However, whether or not you decide to remove the valve is up to you. If you dont care about **** coming out of your tailpipe, then removing it wouldn't cause any harm.

Hope that helps...

:cool:

where'd you get that info.. i couldnt find it under search...
-also...i plan of keeping it there but capping off the tube from it to the intake piping. b.c i'm moving my intake to the other side of the engine bay when creating my new intake after moving my battery.

this couldnt cause my cat to rattle or make noise would it ... i think its just the heat sheild but im just making sure

[AKADriver]

probably just the heat shield, BUT, if your cat is blown it could very well rattle from the chunks of catalyst breaking up.

Geez...

The AIV exists only to let fresh air into the exhaust at idle. This keeps the cat hot and happy.

If you have no cat, it is useless.

But you should have a cat if you drive your car on the street.

yeh yeh i dont have a cat....i am hopefully going to be putting in a ka-t soon...so that was the logic behind that...and when i bought the car the cars cat was F***ed...when we took it off it was just a big hole. yeh i lost a lot of torque...but itll have to do for now.
