I did it myself at first, driver side was not too hard just have to keep trimming until it doesn't hit the fender liner. I followed the DIY which says bolt the pass. side duct to the oil cooler then trim the duct, I kept trimming but don't see any way the duct will line up to the bumper. So I took it to the body shop and they had to cut the oil cooler mount off the duct and glue it to the bumper with urethane. IMO that's the only way the duct will line up with the bumper perfectly. It still lines up with the oil cooler just isn't bolted on to it. I wouldn't do it myself again, just way too frustrating and time consuming lol
