@Vinnie, it does sound good and mine does the same when you put your foot down. it is the air getting sucked in which makes that noise, it has made the engine sound different too from when it had the standard airbox in but i don't mind the sound. hope that helps
I think he has the stock blow off. Multiair engines (170hp) sound like that, the older mitos with the T-jet (155) don't have this flutter. And as a 155 owner, I'm so sad I can't do this on my mito :'(
Hey, i have this on my 135 Multiair, and it sounds great when your booting it, but when driving in normal mode and you put your foot down it makes a horrible sucking noise, and makes the engine sound crap, do you get simular issues?
Hello ,I bought the KN RF-1005 Air Filter ( Not Kit), there's this air filter in the KN 57I-0679 kit. Same as your filter. But i dont have a plastic hose reducer for installation. Is it possible to share the measurements of both sides of the hose?
Thats the air being fed back through the turbo after being compressed, the sound you hear is the turbo compressor “chopping” the air. People will try and tell you its compressor surge and that its really bad for your turbo but thats not exactly true. Compressor surge is when you get this noise whilst you have positive boost pressure and your foot is to the floor. This is bad for your turbo. However this noise when the engine is slowing down is fine, nothing at all to worry about in low boost applications. A blow off valve or recirc valve will make a “pssshhhh” noise as it vents the air to atmosphere (BOV) or re routes it back to the turbo intake (recirc). Hope this helps.

@James Yes, this is with the stock BOV, all i have replaced is the original airbox/filter with the K&N. It sounds better than the video shows it too
Isn't it too close to the engine? It might take heat from it. Sounds awesome!!
Think it has an air cooling device? Could be wrong
hey when u put it in did u have to remap ecu or was the engine fine and did u get any errors or warning lights from ur car

Same problem here , how did you solve it?
blow off how? 😊
have you got a blow off valve on too ?
Is this just with the stock standard BOV?
where can i buy this kn filter??? Also does it improve horsepower,torque and fuel consumption or only this impressive sound? how much does it cost?
K&N air filter are very cheap just cost $60 only.
Hi. What is that sound when you take your foot from the gas pedal ? like is drowning or something ?
Andrei Vidu It’s the turbo blow off if I’m not wrong.
