Renegade Hybrids had a nice looking LE type front valence with a relief for the oil cooler.
You can find the info here:
CUSTOM FRONT VALANCE: Custom fiberglass front valance. Assists with proper air intake into the radiator. While this piece is not mandatory, as you can modify the existing front bumper, it will aid in cooling due to its ideal design. Adapts to all model years. ( picture )
