These die-cast wire looms evenly space four spark plug wires on our 'Olds-style' valve covers (room for 8mm wires, larger if you modify them). These looms completely cover the oil fill/pcv valve grommet holes. You will need to modify the loom (by perhaps boring a large hole) to access the valve cover's 1.22"' hole.
Acorn nuts are provided to make quick removal of the looms simple and easy (12-1/2" mount centers). The "Rocket" decals are a dark red color. Order one set of looms for one set of valve covers.
Not for use on stock Oldsmobile valve covers. Designed for use with S/B Chevy valve covers 910-8202.
