Am I missing something? If you do this, you'll have an open hole in the inductions system between the air filter and engine, thus sucking in unfiltered air? How would that be good? I must be missing what your saying.
Why NOT buy a CAI?
The resonators in the induction system shouldn't hurt performance (perhaps that conventional wisdom is wrong), but the best way to keep a vehicle reliable and dependable is too keep it stock and well maintained. I think that is why you see so little interest in fiddling with the induction system. People either want it stock to be most reliable or they get a CAI.
I have taken the air box on the TB/engine off several times and looked it over, but admittedly NOT extremely close. I've never noticed any slots or openings like the original poster was talking about in his post. I will look closer next time. If they are their I can only imagine they are flaws in production or some sort of safety feature to prevent sucking up water from a flooded air filter box?
You are confused, my post wasn't very clear.
That airbox/resonator has secondary passages for air to be redirected to which quiet down the intake noise. Blocking off these passages may
improve the airflow.
No hole would be opened to open air between filter and throttle body, there is a water drain at the bottom of the air filter box (before the filter) that may be uncapped and allow for increased airflow in that area as well.
Why not buy a CAI? I live in CA, and 50 state legal CAI's are ridiculously expensive, and I like a similar to factory look, I am looking into trying the Liberty Intake elbow (instead of the black box/intake resonator) and trying to find a way to replace the flexible hose with something that would flow better (maybe black PVC and black silicone couplers?)
Thanks for the response!
I am not much of a fan of the looks of most "CAI" kits, though the airaid JR would be nice, but alas its 5.7L only.
