^^^Post a picture. Also, you won't be able to hear it under light throttle. Can you hear it in 1st gear at or near redline?

 

There's nothing on the car that keeps an intake from "not working" in 1st and "working" in 2nd. You're probably just not flooring it.

 

No I have floored it and it sounds completely stock its really odd.

 

I just installed my K&N FIPKon my 07 S.
Now whenever I turn my car off I get a soft pop sound from the in take.
It almost sounds like a backfire as the motor shut off.
Any ideas from those that have done this before.
Thanks in advance.
Joe

 

I would step through the install procedure one mroe time to make sure nothing is connected backwards. I know once I did I found two crossed hoses.

Follow these instruction..

I think that's normal. My older cars that had a K&N air filter did the same thing.

 

[QUOTE=alSpeed2k,Mar 5 2010, 11:37 AM] I think that's normal.

 

The only thing I never did was disconnect the Battery.
I will recheck everything, but the link seems to show an AP1 install.
there are a few things that are different
MAybe this is the problem, this is the shot looking down my hood.

But I don't see how.


The rest seems in order
Let me know what you thinK

 

^lol, I swore I had answered your first question before, now I realized you posted in two different threads! Anyhow, the sound will be louder for you b/c your hood has that open grill. Also, disconnecting the battery won't change the sound, doing so supposedly helps your ecu to learn faster.

 

Yea I saw that was you in both threads.
The sound when I am drive is cool, but when I shut it off that blow back /pop is odd.
I do have to try the battery disconnect for the ECU
