Sounds like you are more interested in bashing the BDJ product on this thread then seeking input on a intake upgrade. The moderators already deleted an ugly thread over this issue.
If you don't like something - don't buy it. It's your car, your money and your choice. No need to disprove or bash anything or anyone.
If you were just making this for yourself and not trying to market this as a product for sale I wouldn't question a thing and just try to make a few helpful (hopefully) comments. But since you seem like your going to try marketing this thing for sale, I don't think my questions are over the top. Trust me when I say I haven't begun to bash, trust me.

Sorry to get your panties in a bunch, but If your going to be selling something your going to get people who are going to ask real questions. Like I said before I do like the way it looks the best and I'm actually pulling for you (believe it or not) that you get this thing right, but don't take my hard questions as badgering or bashing that is not my intent. Just curious will you be dynoing your setup with the engine running for a while, hood latched down, and no fan blowing in front?
