Hey guys, I was looking around my engine bay earlier with my engine running and I noticed that when idling there seems to be a howling noise coming from the intake. But as soon as it sucks in air I don't hear anything, you can barely barely hear it in cabin..actually you prolly can't just my mind messing with me. I was wondering if this is normal for our cars or there's something wrong?

Well here take a listen:

Sounds like the secondary air pump. I assume you have an AP1.

My car as this dull hollow howl sound when its idling if you listen right by the intake. I'm in an AP2 with K&N FIPK

Ahh, yeah. I'm looking forward to buy fipk intake also from a member here in the forum. Hopefully it's gone if I switch it, if not ima see a buddy of mine and we can trade air pump to see if that's what's causing it. Thanks!
