Save your money. If you like the cool factor of the sound of a CIA under the hood and some cash to burn by all means drop the cash. Good luck out performing the OEM air intake system in your truck. There are so many better mods you can put on your truck that will not give you that well that was money well wasted.

I link this video often when the "which CIA should I get" post comes up. I know it's not done on a truck but these guys have put the effort to debunk the CIA. I'm still waiting for someone/anyone to provide performance or MPG gains from an aftermarket CIA.

It's worth the watch:

Reduced engine life for better sound is not worth it to me.
