just put in my fujita intake, looks and sounds great, but when i really get on it and the RPMs jump up real fast, i hear a high-pitched whining/screech...i checked to see if it was rubbing up against anything, didnt seem to be that. i was thinking it could be the filter breaking in or something like that? any thoughts?

 

I installed a fujita CAI last year, improved my gas milage, and the Max perfroms great, at 6000rpm it sound like a european sports car.

 

I also installed mine 2 days ago! Bought it from Raz and wow it sounds great. When I first installed it I went for a test drive then suddenly my car shuts down. I was so pissed then I went to take a look...bamm the CAI just detached lol....I guess I didnt screw it tight enough I also had to make a homemade rubber mount since someone forgot to ship it with the intake lol :P. Well overall everything is fine after that. Maybe you should reset or something...

 

The filter doesn't need to break in. The screeching you are hearing is the air being drawn into the intake. I put a Fujita on my wife's Altima, and a Nismo on my Maxima. The Fujita is MUCH louder than my Nismo...when you get on it, it sounds like a scalded cat!

 

thanks for the input, appreciate it

 

dude - you are going to LOVE the Jita (if you already do not) - Best is going under bridges

 

put it in neutral and have someone push the gas while holding the break and listen and look under the hood. should help pin point the problem.

 

Even though dont have a Fujita I know the sound!!

 

The sound is normal dude.

 

so i had the battery disconnected for the install and now my sunroof wont open...itll go back with the incremental button but not the lever that makes it go all the way back automatically. anybody know how to fix it?

 

Make sure the sunroof is fully closed, then push and hold the tilt switch forward or close position for 2 or more seconds.

 

pics and a vid would nice

 

i have same one n i ran into same problem... i installed ... got in car... drove out driveway block away car shut on me.. i was WTF! ! ! ( it was my first time doing CAI) ...so i tried starting it few times no luck.. opened hood n saw CAI was off... so i was like ****.. then just pushed it back to my house.. n reinstalled it.. ( made sure it was tight ) .. went on ride n heard same sound... but you are suppose to have that sound because its just air getting pulled in .... all normal...

 

Talking about fujta cai. mine's snapped from the bracket that bolts to the body,its still under warranty and they are gonna send me another one. but here is where it get interesting,my engine use to knock every now and then with the cai,now that i have the oem intake box back on, the knocking is totally gone. now im a little concerned bout installing it back...any 6 gen geeks out there that can explain to me whats the issue? please help, i miss that sexy roar @ 5500 to 6000 rpm....lol

 

My first question to you would be what octane fuel are you using?

 

Shell v power or Mobil. 93 octane

 

If engine knock is what you are actually hearing, then you have a lean condition. You are already using 93 octane, so we can rule that out. Engine detonation is caused by not enough fuel. I wouldn't think that adding just a CAI would cause a lean condition in the engine. I have a Nismo, and I haven't experienced any detonation. SOME detonation is normal...so I'm told. Excessive detonation is not normal, and is harmful to the engine.

 

I was reading about this problem recently on a tuner magazine,that a cai can trick the MAF sensor and trigger knock sensor,or cause air/fuel ratio confusion.i didnt had no codes or ses light on though,and like i said the engine knocking is not there no more.....i just wanted to hear some different opinions. thanks for your help Hawaii.

 

Back when I was running my supercharged Mustang, it was known that if you over-oiled your K/N filter, then you could end up getting the MAF sensor coated in oil...thus fouling out the sensor. Just another thought.
