I keep looking at the BDJ intake and wonder how its not sucking in alot of hot air from the engine. The needswings intake is getting its air outside the engine bay so I can logically see the benefit. I read some previous posts that the duel intake would be too hard to get both intakes outside like the needswings. I have no experience and don't own any aftermarket intake right now, but have you ever thought of making air boxes around the filters with a direct port to the outside air? Like I said I really know nothing about these things, but it would seem beneficial to your system since both filters are located in the engine bay. Just a thought, not trying to question anybodys "know how" or anything.
