no the air box on the j is not restricted no baffles or anything like that in there like the H
i have read alot of posts on this subject over the last few days
i agree there is no real power gain and the resonator may play some part in
smoothing out the air flow Helmholtz resonator waves
so maybe it is just the placebo effect of the car sounding a bit better
but it does feel better all the same and no ill effects can be noticed
i think as the resonator is fitted after the air box and on the intake pipe before the air box
it may just be for noise reduction if it was fitted from the air box to the throttle body then maybe it works like said in the e how posts
basically i have no idea but as said for some reason it feels better
