I got mine from CarID, but DAMN the price has gone up since then! Thanks for the tip on oiling; I'll be sure to use it when I change my AEM one out again! I have some good pictures of the intake when it was new on my old laptop, including a shot of the dual passages. I can post them sometime if you want! The only supporting mod I had to do was buy a new, stronger PCV tube... the included one is too flexible and pinches at the bends too much for my taste.
The most major mod I'm considering is a Stage 1 cam... I'll probably knock that out if my HG goes. I've been told it gets along pretty well with stock internals.

BTW, gearbox was a huge motivator for me to get involved with this site, even though he vanished into the sunset before I joined. He was really particular about his ride, but his goal of keeping his Civic running for as long as possible matched up with mine. His review of the intake is here and he eventually went with a Dryflow filter too.

My WR Secret Weapon is awesome! You wouldn't even know I had it until I punched the gas; it's really quiet for regular driving. The foam filter is nice, but it takes forever to dry and is more efficient when you put the special oil on it. That's why I changed it out with a Dryflow when it got dirty. I'll change it back when this one needs cleaning too. I hope this helps! :-)

? I think it is integrated with manifold, or something like that

I'd be happy to help! I got my kit 25% off during their Thanksgiving sale (I believe GolNat did the same a year prior), so keep checking their site every now and then!
