So as I accelerate there is this squeak at about 4000 rpm, almost like a turbo psssst, if you know what I mean. I think it sounds like a vacuum leak, took my g to Modern infiniti in Greensboro and they told me the noise was due to me putting in a k&n air filter into the factory air box. Do they think I am an idiot? I sold cars and worked on them my whole life...hell my stepfather used to build the Caterpillar D-9 bulldozers and grew up at franklin county speedway with his brothers racing the likes of Dale Earnhardt, Richard Petty, and more. I know this is not because of the air filter. Oh and to top it off when I dropped my g off I asked him they had the license plate holder that screwed into the tow hook adapter in the front bumper and he said yes. I told him if you have to put holes in my bumper do not even put one on. I picked up my g yesterday... guess what...I have two holes in my f*^%&%$ front bumper. Then the ******* had the nerve to charge my 75 dollars for the plate holder!!!!

Sorry just wondering about the psssst sound.

 

I have seen aftermarket intakes/filters make a sound like that on the G.

 

My JWT Popcharger does that. Not when I give it full throttle though.

 

No mine only squeals around the 3500 to 4000 rpm range then it goes away. I understand it doing it with an aftermarket intake but I only replaced the factory filter with a k&n filter made to OEM specs. Does it really breath that much better just with the filter then I need to get an intake.

 

Wow so I called Infiniti USA and they called modern infiniti of greensboro and the service manager said he would re-paint my front bumper and fix the holes. hell yea! Class act. But now I have to drive back to greensboro and they are going to start that oil burning prob. i might get a whole new engine. Maybe I can talk them into a 2007 engine so I will not face this prob again later. They should do this anyway just so you dont run into the same prob. Obviously something is wrong with the "high-rev" engine.
