disappointment! Looks like the 13 3.8 does not have a carbon filter. Was so excited that I'd gain an extra mpg or two.

It's okay, You guys get better mpg than pre-2013 anyways lol

Well I removed the carbon filter about a week ago, but I haven't really noticed any difference from before.

My MPG is still about the same, but I suppose there is a little more pep at the lower RPM range, though that could just be a placebo effect.

I took my carbon filter out tonight and from the short little test run I did, it seems to idle a little better and has a little more pep way down low, but nothing drastic. There's not even a huge difference in the sound. We'll see what the MPG do over time. For the 5 minutes I put into it, I'd still say worth it.

Note the results I felt were from removing the carbon filter AND throwing a K&N as well.

Just removed my carbon filter... What a difference! My car was always hesitating on shifts 1-2-3... now it's smooth as butter! Noticed a bit of a deeper engine sound also!
Great DIY!

Thanks Cliffsta, for these instructions!

New 2012 3.8 owner here who just joined. I was looking for info on K&N drop in and found this so I will do both together in the near future.

Well, if you take the carbon filter out, you need not mess with a K&N. The stock paper filter has the same hi-flow rate as the K&N (with none of the oiling problems). This hi-flow paper is necessary due to the carbon filter being there - together they are like an ordinary paper filter on a car with no carbon. You can still do a K&N, but there will be no performance benefit.

Going to probably do this on my 2012 3.8GT in the next day or 2, just wondered how many of you guys without intakes have done this?

Any more thoughts on if K&N drop in would be of benefit too?

 

[hockeydoc33]

DO THIS MOD!

Goal for tonight.

K&N flows more air than paper filter. Been shown via tests for some time. Not sure where the other forum member gets his facts from they do not, other than making the statement.

Doesn't make a huge difference, but at high rpm, more so.

I just tried doing this on my 2015 3.8 Ultimate and it didn't have one.

 

[inertiamonster]

Correct, as reported just a few posts before yours, the 13+ 3.8s do not have a carbon filter.

Mine didn’t have one. ‘16 Premium from Canada.
