I just installed and injen intake, and when i hit the gas at a certain point when i press downt he gas pedal it makes this high pitched whistle noise, almost sounding like a blow off valve? it was cool for a while but now its anoying. i checked all my fittings and clamps and they are all on tightly....any ideas?

thanks

 

my frankencar and injen intake did this, i have headers now and the sounds is exactly like a blow off valve with no whistle ...weird ?

 

yeah im running prety much stock and it all depends on how hard im getting on it wether is sounds like a whistle or a blow off valve

 

The whistle is normal. My injen does the same thing but only at low RPM. I don't even hear it unless I have my window rolled down and my stereo off. It bothered me at first but now it has grown on me.

 

a lot of CAI setups I've seen make this noise also. not just on maximas, my friend's mustang does it too. I don't think its a problem... correct if I'm wrong, anyone?

 

no i checkd over and didnt see anyhting wrong, was just wondering if it was unusual, and yeah meanbean same here i can only hear it at low rpms also....

thanks for the help all!

 

its normal on any max with the resonator removed. I like the sound now.

 

i think it should be fine cuz i get the whistling too....i have a bomz hybrid intake with K&N air filter

 

I get the whistle as well. Sometimes it's quite annoying, sometimes I will just thorttle the gas on and off to hear it whistle almost like a BOV. I'd say its normal, because even with the whistle I felt a very nice gain from the intake, so I figured everything was fine.

 

yep yep, i have the JWT and i love that whistle. pimp pimp hooray!

 

Every maxima I've ever owned or ridden in that had an intake had the whistle. But I wouldn't go as far as to say it sounds like a bov. It's more just anoying enough that people think the reason I beat them is that it's turbo. I hate the whistle

 

I have that whistle as well... Pass by a civic at low rpms and it will scare him away :P

I got the whistle after I cleaned my IACV I didnt have it before, if i did I didn't notice.. Im gona take out the IACV again and make sure everythings on right just to make sure.. Kinda annoying if you ask me.. lol

 

Ditto. I like to play with the pedal sometime to get a melody out of it.

 

i love the whistle noise its a very unique sound and i think it sounds cool.

 

(I have and injen CAI) I was like you guys. I liked the sound at first, but now that it is getting nice out and I drive with the windows down the whistle more annoying than driving behind a 90 yr old short lady who has her directional on for the last 45 streets. (Sorry about the stupid comparrison) Does anyone know how to fix this. The past replies didnt say how to fix if just if people liked it or not. Now with my exhaust on I want to hear that instead of a bird that could be stuck in my intake.... I should check and see if there is a bird in there!!!! (Stranger things have happened)

 

Even on my 5th gen, i have the same problem. i've had my injen cai on now for about a year and it's gotten worse, but it's grown on me. i've checked everything out and it seems fine. i actually did have someone ask if i had a turbo in my car b/c of the cai. he said he liked the sound even though it's N/A.
