So I checked the kit for the 2011 and it only gained 6hp. Why such on improvement on the 2012 and so little on the 3.8l.
Note please no 3.8l haters responses. Just want to know any facts from ripp as to why this may be.

The 3.6 has variable valve timing allowing the cam profile to change through the RPM - the gain is steeper through the RPM as a result because it makes better use of the added air through the entire RPM band. So it will show more gain in more RPM points as a result. The 3.8 has a standard cam profile and does not utilize the added air as effectively in NA form.. The gain it there but by percentage spread through the entire rpm band thinly... As a result the gain is less but still there..
We maintain that if you want to stay NA with your 3.8, our header and tune combo with any air filter system is the best bang for the buck and no other combo has proven otherwise on any dyno pass we have seen. The pro to our air kit is the velocity stack inside, the fact that its protected from the elements and lastly its the only CAI kit that's compatible with a snorkel.

The intake looks great. RIPP, do you know if the intake produces a lean condition and if so does the Jeeps computer automatically adjusts its timing to address that issue if there is one ? Thanks.

Ripp,
Do you have any idea how this will affect IAT's when the weather turns warm? I pull a 3200# boat and trailer through the hills. I could use the extra power and torque, but I'm worried about detonation in the summer when the under hood temps are high. I know it's near the stock intake location, so this is just a question, not an objection.
Also, is the filter washable or replaceable? Where can I buy a spare filter?
Finally, are there any resonant frequencies at particular RPMs? I can't stand to have a long trip with a loud underhood drone the whole way.

It is a high quality washable cotton element - replacements would be available through RIPP - (on their way

have you done any dyno testing with the hood closed? IF so how did this affect the dyno numbers? I know many of the CAI for c5 vettes lose some performance with the hood closed. Just wondering if jeeps perform in a similar way.
