      Description

      A Quick Upgrade With a Big Visual Payoff. The Roush Polished Billet Radiator Cap takes less than 15 minutes to install, but has a lasting visual impact under the hood of your Mustang. The polished finish adds a sleek shine that will perfectly complement other upgrades you’ve made. Quality construction ensures it will be an upgrade you can enjoy for the life of your vehicle.

      American-Made Quality. All Roush radiator caps are manufactured in American, raising the bar for quality of construction and materials. Constructed from high-quality billet aluminum, the Polished Billet Radiator Cap is designed for durability and a long life. It stands up to corrosion and wear, and the engraved Roush logo will look brand new for a long time.

      Classic Design. The polished finish of the radiator cap by Roush will add a sleek shine to your engine compartment. It is the perfect complement to other polished upgrades under your hood, and adds a classic look that can’t be beat.

      Simple to Install. All you have to do is slide the Roush Radiator cap directly over your factory cap, and adhere it with automotive grade double-sided tape. Because Roush CNC-machines their radiator caps, you can be confident that it will be a perfect, hassle-free fit.

      Application. The Roush Polished Billet Radiator Cap is designed to fit all 1996-2023 Ford Mustangs.
