Weird noise after installing after market air intake filter

Hi guys, I have the car listed above RS model and just over the weekend I installed a K&N Air Intake. Upon doing all the things the directions told me to do I completed the install as it was pretty easy but now the engine or something is making a weird noise. I checked the heat shield to make sure nothing was rubbing, I checked the fittings and brackets to make sure nothing was loose, I checked the hoses as well. Everything seems intact but still making a weird noise. Kind of like two metals rubbing.
