I recently installed the Injen CAI. Around 4000-5500 RPM, I hear a hissing noise which sounds like turbo's are spooling. I am not sure if this is related to the intake or if it has to do with the fuel pump. Does anyone else have this problem.

Thanks in advance

 

Thats what it is supposed to sound like. Its the sound of the air being sucked through the filter I belive. The sound is the best part of the whole system.

 

Dito!

 

Dito 2

 

Ummm....ditto 3?

 

ummmm...ditto 4. Thats what i thought it was. I really like the sound of it!!!

 

First CAI, huh?

Um, ditto five standing by.

 

DITTO 6!

 

Do I hear "ditto 7"? Sounds great, doesn't it?

 

sounds even better with a crawford plenum

the hissing sound is louder.

i love this combo.

 

after the filter gets broken in, it will subside a little .

 

If it's really loud, and doesn't sound right, MAYBE one of your clamps isn't tight enough? But otherwise I say "ditto 8?"
