Dual intake, 3500~rpm noise?
When I roll into the throttle ive noticed this different noise around 3500 rpm, hard to describe, almost sounds like low volume flutter/rattle, seems to be directly correlated with 3,500 rpm and throttle (vacuum actuator) so im assuming its just the dual intake opening and closing, just curious if others have noticed this different noise?
I cant hear it once engine revs get higher because the exhaust drowns it out or it goes away

Haha! Rookie ISF (new) owner huh?!? Lol!
yes, this is one of the main "features" of the ISF (and all the F cars if I'm not mistaking). There is a secondary intake that opens up at 3700-3800 rpm. PLENTY of threads on this! A quick search will have all your answers revealed!

Its very hard to make out in the video but yea it does seem to be something I hear right there at the 3600~rpm spot and only after 3600 rpm so obviously has something to do with the dual intake, just wasnt sure if the dual intake opening made noise like that, just the sound of air rushing in? My car does have a takeda intake as well.
You can kinda hear it if you listen very carefully after 3600 for a fraction of a second

If you have a Takeda intake, you do not have the dual stage intake like the factory airbox gives you....

"However, the Takeda is different. The reason I sold my Injen for the Takeda is because it brought back the ISF Dual-Stage air box. The Takeda intake cone filter is made to fit into the stock box, with an enclosing part of the Takeda heatshield."
my setup looks like this, correct me if im wrong but isnt that connected into the stock air box over there with that dual stage solenoid with all the little vacuum lines?>

Are you sure? I read the takeda intake retained the dual stage air box like factory?

But I will say that ALOT of people question the performance (or lack thereof) of the Takeda intake. Do a quick search and you'll see....
