Verus Engineering Engine Bay Cap Kit - FHS Oil CapCover up and replace the lackluster plastic caps that come on your factory Ford Bronco with a cap machined from solid aluminum. The caps are machined in house and offered in three common colors to add color to the engine bay. The caps are bright anodized and laser engraved. The units install easily within minutes with no tools required. Anodized parts can potentially fade over time due to engine bay heat.
