Did a quick DIY duct for my GSR. I have the JDM fog deletes, so I wanted the space on the driver side filled up. Always had this silicone duct when I had the ETS intake with small heatshield (can route duct behind driver headlight and point it straight up to intake filter. Had it secured with an L bracket to the OEM intake mounting points. Now I got the MAP 3.5" intake which has a more substantial heatshield, so I cut a hole in it. Pictured is still my 3" ETS intake in with the MAP heatshield, before I get retuned for the bigger intake. Doubt this will do much, but it was easy to do so why not.
