INSTRUCTIONS
You’ll need to remove the plastic pass-throughs from the OEM intakes that are next to the radiator on both sides. A real PITA to remove but can be done to keep them intact incase you want to go back to stock later on. I ended up snapping both of mine off (got impatient and frustrated) so mine will be staying this way. The driver’s side opening is smaller (like around 2.5” – 2.75” ) so the 3” tube will deform into a “D” shape going through the opening. I used a single T-bolt clamp where the 70 Deg. Tube butts up to the filter box tube. Just made sure it aligned right over the joint where they meet inside the couplers. All told, average price is under $300 depending on where the parts are procured. All parts shown are what I used for my particular setup. The silicon tubing is also available in black and red. You may also find other sites that carry other colors, like yellow and green. Just make sure that it’s at least 3 layers, The more layers, the harder it is to collapse. Also I had to trim the outer flange all the way back to the rectangular opening on the brake ducts to make them fit right.
