I will be replacing the stock air filter box for a higher flowing air filter with a heatshield. Below is a picture I took, can someone please tell me what the heck the circled thing in my picture is and it's purpose, and what the heck do i do with it once i pull it out of the air box, and where i can relocated it for it to serve its function. I'll be getting a getto Ractive filter, how do i go about cleaning this, or is it simply a throw-away-after-x-period-of-time brand of filter. Thanks in advance Ceg'rs.
