oem intake tube/Airbox/MAF is $HIT
Bryan,
You may very well be right that aftermarket boxes choke power at higher rpms. If you look at the dyno I posted, the pull with no filter DID make more whp over 6500rpms with a peak gain over around 7whp at 7500rpms. Also, I'll post up the same graph again, but this time with the air/fuel graph expanded to more clearly show differences. My guess is that we are both right: there ARE gains (you) but they aren't dramatic enough to justify the removal of the box (me).

I have been wondering this myself, I am getting rid of my ATP gt3076 kit for a green here this summer, my tuner Tym Switzer wants to use a stock box and a drop in filter. He says he runs a stock box on his car and loves it. I am going to bring in part of my setup and do a back to back stock vs my custom K and N style intake. Might be awhile though...... I just dont know what to belive!!!!!

FWIW, you may want to re-read that entire discussion, and consider the data and the 'devil in the details' along with it.
No need to get angry with us, we're just illustrating the potential effect of variables that you didn't consider that affect the outcome of such tests. And yes, 10 days and 10 degrees difference (according to the weather records for Hayward, CA) do create issues of variability.
No one is questioning that a good intake isn't potentially worth something. What needs to be done when testing different air intake assemblies has been discussed ad nauseum, and it's a bit tedious if quality, reliable data is going to be generated. We didn't make it that way, we're just illustrating what and why for the benefit of those who may be misled into believing that bolting on an aftermarket intake is going to net them 25whp.

, those alone would perform worse than the stock pipeBryan check PM's.
