@Jack Flynn What year is your Aspen? Looks like a 2007 or 2008 as your Throttle Body is in the back facing forward. The point of this thread was for the 2009 which does not have an option for a CAI as the Throttle Body is towards the front of the engine and facing straight up. See post #23-#25.

 

In 2009 Chrysler used the new 5.7 just like Dodge did in their Rams

2009 5.7s are different animals from previous years.

I always get out my sawsall, hack saw and or plumbers straight saw and cut open the factory air box and install a K&N filter.
