Hello everyone,

I am so sorry about the n00b question, but where is the IAC located on a 2013 F150 King Ranch 3.5 Ecoboost?

I am very new to trucks, and am eager to learn. I have a whistling noise driving me nuts after installing a K&N cold air intake that I am trying to track down.

Thanks in advance!

 

Put the stock air box back on. Full Race has confirmed on dyno that aftermarket CAIs add nothing to the EB. The stock air box is more than capable. The whistling is the turbos spooling.

 

Thanks, Kenferg1, but no thanks to your reply.

One dyno might say one thing, another might say another. There are arguments to both stances on CAI's. Full Race, while they may be credible, cannot make a blanket statement that all CAI's are useless.

Also, the whistle that I am referring to is NOT turbines spooling. I said a whistle is what I am dealing with, not turbos making their presence known.

 

Double check the installation might have something that is loose or misaligned

Definitely check your install, something out if kilter there...

 

There is no IAC. Idle speed is computer controlled using the throttle plate.
