well benefit is all in the eye of the beer holder, you know. some people have no trouble dropping 350$ on a piece of plastic for looks and sound and some dont feel its worth it. you have to decide which camp you are in.
I am some where in the middle. I removed the restrictive carbon filter crap in the top of the air bowl and threw in a drop in washable airaid filter that I had laying around from my last ram.
I am very happy I have just the right amount of HEMI sound without the open air element resonances and picked up some throttle response too.
all that without breaking the bank!
