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 :slayer:
