Hello. I have a 2008 G35 sedan 5AT with prem and sport pkg. When I accelerate with the gas pedal more than 30%. The engine makes a quick pssssst air sound when the automatic transmission changes gear. Sounds like turbo blow off valve. It's not that loud but definately noticeable. Sound is louder when I drive fast or full open throttle. Do other G35 owners notice this? Thanks.

 

yeah i can hear it too.. sounds cool

 

Yes, It even sounds better with an air intake system.

 

It's common... we all hear it.

Here's the thread.

 

it's just the air getting sucked in

 

Thought you guy would like to know ... I don't get this sound anymore after I put an exhaust in. Anyone else with aftermarket exhaust still getting this noise?

 

yes i have the stillen exhaust along with the stillen intakes and its not every single time but i'd say i notice about half the time ?
