what is it?

[cargle]

yesterday I added a CAI (gonna put a pod on soon though), when I was removing the existing setup , I pulled out a 'container' (big black box) of such, just wondering what the hell it was used for, was it to balance the air or something?

It wasnt your resonater was it?

It could have been, dont know too much about it?

if it was the resonator was I supposed to put it back?, what is it used for?

[Snuffy]

basically makes the car quieter... less intake noise and such...

Yeahh sounds like your resonator.

Just keep it out and your car will sound sweeter :)

There is a good three page article in the Jan 1999 issue of Fast Fours & Rotaries regarding intake setups.

It says that not only does the resonator reduce noise, but also creates some sort of negative pressure. The article describe it like a turbo running negative boost (eg -.75 psi).

Also says you shouldn't use flexi pipe that has a corigated inside (should be smooth) as this will disturb the air flow. Suggests you use drainage pipe with smooth bends.
