Edelbrock part #41181 is a polished coil cover designed for the GM Gen III LS Motor. Our covers will mount to LS series motors with stock center bolt style valve covers and accept stock Delphi coils with GM PN 12558948 or aftermarket replacement. Design eliminates stock mounting bracket, by allowing coils to mount directly to underside of cover. Covers are intended for use on street rod or custom applications and as such, may fail to clear hose routings found on stock vehicles.

Use a dummy; bolt secured with a nut to fill any mounting holes in the coil cover that do not correspond with a threaded boss in the valve cover.; 4.
