So a little update, I've been busy with work lately and neglecting the car. I got the M370 manifold but I had to tend to other business before doing so.
DIY: Repair Damaged AC Lines Because by Aftermarket Intakes
So like I mentioned before, bought the car used, it had Stillen Gen 3s on it when purchased. I didn't know to check and make sure whoever had the car before me installed the intakes with the hosing to protect the AC lines. This was not done and two years later I discovered an AC leak. Nissan quotes it as a 4-5 hour job which adds up considering the part is only $27. So I replaced it and wrote up a DIY just incase anyone else out there runs into this issue.
