(G) Air Box Modification

bitchin! I just did this to my 2.0 20v HLXand I'll be damned, what a noise. I've got a cat back stainless too and this thing now gives old people heart attacks. It definately feels like it pulls smoother through the revs, and the faster you go, the more cold air - terrific.

Hello guys, i have Bravo HGT147 and have made some modifications to the intake system. The first thing i did :

Remove the air box and put cone air filter there(see the attachment)

The second thing - remove the upper resonator box...and here is my question - what is the function of this upper resonator box? I'm adding some attachments with some manuals:

I think you would be better to go to the Bravo section and ask there

na, the lads alright here

The seconds box is a resenator box, its simply there to reduce the induction noise the engine makes.

mine was removed before i converted to 20vT, i know a few over members here have also removed it

Ry

if you fit a cone filter you bypass the resonator box so removing it isnt neccessary, although i would still remove it because unneccessary plastic has no reason to be there.

M8, I'm talking about the upper resonator box(between the flow meter and the butterfly valve(number 9 on the manual))

PS: Look at this:

Maybe the funny-looking box has another function...?

sorry i thought you meant no.8.


your link is talking about a different type of resonator; one that is used on the manifolds. however it may be true that the resonator on the 20v serves a similar purpose.

Ahha! Finally got round to doing this tonight after thinking about it for a few months... a bit thrown by one off the comments about a screw needing to be undone!?

Anyways, yanked the pipe off, gave the elbow a quick twist and pull, put the pipe back on... 45 secs and a slightly dirty hand.

The result...AMAZING!

Probably the best minute I have spent working on my car.

Did this mod within days of buying my 20v. Sounds awesome. I actually removed the whole intake pipe but after reading this whole thread I am about to go and bolt the main bits back in and just leave the elbow off

Nice to see that this simple mod still gives some pleasure

skeggy thread is up

I have removed this junk 4 years ago on my JTD105, and now i have done the same on HGT.
On HGT the gain is 90% in SOUND...
But in the JTD not only it gives a LOT of power (turbo engines needs LOOOOTS of air! And diesel engines won't appreciate cones, as this filters gives extra air on high RPM but don't have RAM effect on lower RPM... and diesel runs low by its nature!)... it can save your turbocharger!
Bravo and Marea have this stupid intake just behind the FIAT emblem, ok? Sometimes the hood "moquette" soften with water and TIME... and goes down, partially or completely closing the intake.
Figure out this scenery: you pull down the gas, turbo start to suck air from the intake and SLAM! the moquette suddenly close the intake, attracted by the air flow. THIS can severely damage the turbo...
Simply remove either the intake pipe and the moquette and you are safe

Wanted to try this on my 1.6, in fact wanted to remove the whole air filter assembly, I assume I have to remove the front near side wheel, then the wheel arch liner to remove the airbox ?

Thanks in advance
