Seems if I had read this thread long ago I would have saved myself #1 my A/C I wanted that bling and I bought ALL CPE products but this intake has caused frustration & more money to fix my A/C line. Tempted to just remove it and replace it with my OEM system really bummed out the new 2019 FiST less than 1000 miles on the CPE parts and I have no A/C, rubbed a pencil-sized hole in my line in the rear near the firewall. Just to confirm I also have a CPE RMM but that seemed to still not help any for the rubbing issue.
