This is a CUSC Louvred Hood w Duct manufactured or distributed by ModeloDrive and primarily made of FRP material. ModeloDrive FRP (fiberglass) parts are made to a higher standard than most mass produced US market fiberglass parts. Holes will not always be pre-drilled so you still will need to dry fit the parts before they can be prepped and finished. Due to the nature of fiberglass there may be cracks or surface imperfections that need filled and/or leveled. This should be fixed in the prep stage of installation at a professional body shop. Bolts, screws, and double sided tape is not included. All ModeloDrive fiberglass parts require modification, shaving, sanding, drilling, filling in order to ensure proper fitment but generally speaking less than the competition.
