Air Leak Sound

[BOYCI3]

lets say my car is in neutral engine running, I put my foot on accelerator slowly. Between 1-2 revs. i get this constant sound. sounds like an air leak (whistle sound). So every time im driving changing between gears i get this sound for like a split second but over the time its getting bigger and louder.

Any suggestions ?

my friend thinks i have some air leak, if i do is this bad ? lol

You really gotta give us more then that, Look in the log book for an engine code?

Take a look in the service book and look for one of the codes in bold below:
(First Page of the service book to the left, 3rd Line, Last 3 Letters on the sticker)

1.6 2000–2006 I4 16V AUS/AZD/ATN/BCB 1598 cc 77 kW (105 PS; 103 hp) @ 5700 rpm 148 N·m (109 lb·ft) @ 4500 rpm
