| PROFORM breathers and oil filler caps vent crankcase pressure while finishing the look of the valve covers. Push-in styles fit the standard 1.22-inch valve cover grommet, with twist-on, clamp-on, and screw-in designs covering other setups, and PCV-compatible options keep emissions systems intact. Finishes span chrome, Black Crinkle, polished, Shark Gray, Carbon-Style, Chevy Orange, and red — most matching PROFORM valve covers and air cleaners so the whole top end coordinates. Many carry officially licensed Bowtie and MOPAR emblems. |
