The Xplosive Performance billet aluminium ornament plate (also known as a coil pack or spark plug cover) for the SR20DET/SR20DE engines provide that custom engine bay look, perfect for engines modified or looking to add that custom look. The cover comes complete with stainless steel fasteners. This piece is CNC machined from Aircraft quality 6061-T6 billet aluminium. The cover starts as a 3/8" thick solid billet bar and then precision machined to fit perfectly on the valve cover. Then the cover is highly polished to a mirror finish.
