Wrx Pro-R panel filter noise

[Bikeboy16]

Hi, looking for some opinions/advice if possible.

I have just fitted a Pro-R panel filter to my 59 plate WRX. The car is standard in all other ways. I fitted it myself which was a simple I thought, everything went in and out as it should.

When I took it out afterwards, I noticed a noise, which I can only describe as similar to a very quite dump valve type of sound, with a bit of a hiss/whoosh sound when changing gear.

I've checked under the bonnet with it running and there doesn't seem to be any air leaks, and it doesn't make the noise if I blip the throttle when stationary.

So.... Is this just an induction noise due the the less restricted filter ? Has anyone else experienced it ?

I do like the sound, but just not sure if it should do it !!!

Thanks in advance for your help.

Hi mate, welcome sounds like increased induction noise with the more free flowing filter [emoji51]

Thanks for your thoughts, that's what I'm hoping.

I just wasnt sure why it is so noticeable when I change gear. I'm no mechanic, so I couldn't figure in my head what the air would do when you let off the accelerator/ dip the clutch, if you see what I mean.

The recirculation dump valve puts air back into the intake so you'll hear a little of that and you'll also hear the turbo spooling as well

Enjoy the sound mate :)

Ah right, that makes sense, and would account for what I'm hearing. Now I can stop worrying and enjoy it !!

Thanks again for the replies.
