[Optimus Prime]

I'm the OP and I don't remember if I even came back to this thread since the very beginning! LOL I was just reading through the posts, and I really like what I've seen. A special thanks to CreeperRS for getting solid dyno numbers on the intake. Everything I've read about the changes are the same that I experienced (whooshing sound, better response, and a stronger pull at higher RPM's). I was just looking for info anyone found on the replacement filter and stumbled back on this. Thanks everyone!
