Air Sucking Sound

[b_creative3]

Hi,

I have a 2005 Cayenne S (CPO). I notice when I step on the gas pedal a little too aggressively, there is a big and abnormal "Air Sucking" sound produced from the engine bay. If I step on it softly to accelerate, then I won't hear it. Would you have any suggestion what it may be? Could it be the K&N air filters?

Many thanks,

Andy

It's hard to say without hearing the noise but it could be intake noise form the K&N filters. No check engine light or anything look out of place in the engine compartment?

The air sucking sound is like as if you place a strong vacuum cleaner on the carpet, when I step hard on the gas pedal. The sound appears for only 1 second...

Any thoughts?

probably just your intake...and that's normal

That's what I was hoping for, but the sound was too loud to be normal. I thought some of the folks here might have K&N filters put in so I wanted to see if this happens on theirs also before I take it to the dealer for a checkup.

Thanks,

Andy

You'll get the same noise if you stab the gas pedal in any Cayenne. It's nothing to worry about.
