K%N Air filter alturnated the sound of my 06

[DAMNitzHENRY]

i just put in a K%N air filter in my 06 gt stang automatic, it has no other mods.
after a while of having the airfilter( about 5 weeks) i begin to heard a whistling sound when i hit 2nd gear, and from 2nd gear up at about 4.5. Right now, i dont have ne sound recording of it yet

please help

I have always been told this will happen with any intake. I have AEM on my 5.4 in my F 150 and WMS on my 06 GT and have this whistle.

check to make sure the lid is properly installed. if it is not, then it could be sucking in air through a small gap and cause the whistling.

 

[bigcat]

what did you figure out?

 

[DAMNitzHENRY]

well, from wat my friend had said, its just that a lot of air is being sucked inside my hood so i hear the sound. It only happens at high rpm cause intake is taking in even more air

 

[DAMNitzHENRY]

well, iono yet but my friend saids that its just the intake is taking more air so i hear that hum at high rpm

I've got the same "mod" on my 07 and haven't noticed any whistling.

Noise

There shouldn't be any whistle, just a roar. This is because the stock airbox is a silencer.

 

[drummer]

I have that whistle also. However, it is only at vacume but I also have a Tornado too. When im on the throttle there is only motor roar though.

Something that should be noted to you K&N drop-iner's (yes I just made that term up) is that you're not helping your performance...infact you're probably hurting it! These new stangs are very computer sensitive and even the added flow of the K&N panel filter (which would normally be a good thing) can throw this particular computer off.

I thought, from what I have heard the only way you can throw off the computer on the new stangs is to change the MAF sensor and NOT retune the computer

Or put nearly any other modification in existence on it without a tune.

nah, dropping in a new filter or whole cai wont throw off the computer, it will re learn itself and reprogram itself, compensating for the better air flow, thats what the mass air meter is for, real time data logging to the computer, to make changes. Cause think of it this way, when your air filter gets dirty and the flow is slows down, does your car run as if it was clean? no, the computer reads this and adjusts the air/fuel and other things on the fly. So your computer will compensate for the air filter, it may just take a few miles/minutes to tune the changes. but your thinking, then why retune?? cause the computer can only make small ranged changes to these paramaters, not huge ones to make up for say, a superchargers forced induction.

Yeah +1 what he said^

Any large changes in the amount of air coming in from stock settings throws the CEL. I put the C&L on mine and started it up and immediate CEL light came on, and running horrible. Then I loaded the 'canned' tune from C&L for the octane I am running and re-started the car, no CEL and runs hella smooth. A simple drop-in may not cause it, or your run of the mill CAI that flows near what the stock air box does, will not cause it. Throw a large flowing CAI on a S197 with no tuner and see what happens. C&L sells a reducer you put into the MAF to reduce the flow back to stock, thus not throwing any codes, and costing quite a bit less.

Not sure that a simple drop-in is gonna make much difference power-wise as there is minimal change in increased airflow.

I don't have any problems with whistling and never had a light or anything come on. Furthermore, I picked up about 13 RWHP with the K&N so I hope that's not hurting my performance!

 

[The_Joker]

some intakes will make a whistleing or hissing noise sometimes. My JLT does. But dont worry about it, I kinda like the way it sounds.
