Used Boomba Racing blow-off valve for 2020 Kia Forte GT. Originally $270 but only asking for $215. Used for less than a year and is in perfect condition with original box, calendar, and sticker. Sounds just as good as when I first bought it. Im replacing it with the same exact model blow-off valve, but it'll be the Natural Aluminum color instead of the Black Anodize color so it can match the fully Natural Aluminum Dress Up Kit they offer. Willing to provide many more pictures and videos if you are interested!
