I just installed a k&n cyclic air intake on my celica (0124 for the ST182 model), now it makes very strange sound is this normal because it sounds like some weird music instrument, not cool at all, this is the video:


EDIT... found out that even without the k&n (open rubber pipe) it makes that sound... like the valve opens a very little bit and has a very little opening, than it makes the sound like a flute. what to do about it? could it be that a small trash (rubber by drilling) partical of the k&n has flew into the intake that causes this sound? i dont know if it was before also like this, i had the standard intake and that sileces sounds... anyway, i can't use this k&n if my intake keeps produces this ridiculous sound :s :( what to do!

another clip:

haha that sounds like a flute! I dont know what to tell you without physically seeing it but it sounds like to me that theres a hole somewhere? Possibly....if not in the filter but in the charge pipng itself?

It doesn't even sound like it's related to the intake. The sound seemed random, and not at all in time with the revving of the motor.

There is a 'slurping' noise that is to be expected when running an open pipe or a conical filter. Is that what you are hearing?

its not really slurping as you can hear it's a high tone.

thats the noise from the intake sucking, my weaponR intake does the same thing nothing to worry about

Are you guys sure? I removed the airbox on my old GT once and it definitely did not sound like that and neither with a K&N on my 1MZFE nor on my 3sgte.

Mine sounds the same.

Nothing to worry about, its the intake sucking in air, thats what they do.

yes it's no big deal... i just thought i placed it wrong but its just the sound on very low intense trottle variation... if I put in the gas at full trottle it really gives a nice blow sound.
