Edelbrock's new sand cast aluminum LS Series Coil Covers are a great way to dress up the LS1 in your street rod or muscle Carburetor These coil covers are designed to eliminate the stock mounting brackets on transplanted LS1 engines by way of fitting coils directly to the underside of the Edelbrock cover. They are intended to create a clean under hood custom appearance and will not fit stock vehicles. These covers are compatible with GM #12558948 coils or aftermarket equivalent replacement coils such as MSD #8245.
