So I'm thinking about going Speed Density later this year. I currently have full Perrin intake. My question is, what setup should I go with when I switch to SD?

After ditching the MAF, I will drop the Perrin filter and go with the biggest AMSOIL one I can fit between the ACD reservoir and the intake pipe. Should I keep the Perrin pipe or go with something different? I'm running the stock BOV, so it still needs to recirculate back into the intake (right?).
