Add Visual Impact Under the Hood. The Roush Polished Billet Washer Fluid Cap is a small detail that will have a big impact on the appearance of your Mustang’s engine bay. The polished aluminum finish adds a sleek shine, and the engraved Roush logo is a unique detail. For less than fifteen minutes under the hood, you can install this impressive visual upgrade.

Commitment to Quality. The Polished Billet Washer Fluid Cap by Roush is American-made, which is a stamp of quality that speaks for itself. Fabricated from premium quality billet aluminum, the cap is CNC machined to deliver a piece that is a perfect fit for your vehicle. The high-quality material is corrosion-resistant and has an ideal strength to weight ratio.

Sleek Design. With a polished finish, the Roush washer fluid cap has a sleek look that will complement other upgrades under your hood. The Roush logo is engraved on the cap, adding a special touch that sets it apart from other, lower-quality caps.

Simple Installation. Because the Roush Polished Billet Washer Fluid Cap is CNC machined, you won’t have to worry about an inaccurate fit during installation. Note that this is a cap cover, not a complete cap. Removal of the factory cap and modification to the washer fluid bottle is required.

Application. The Roush Polished Billet Washer Fluid cap is designed to fit all 2010-2014 Ford Mustangs.

          Requires work but worth it!

          All of these cap replacements are fantastic. This one requires you removing the original cap and cutting off the plastic hook that it attaches to before installing, but it creates a great seal and adds pop to that engine bay! 4/5 because no instructions are included. Had to do some googling to find out modification was needed.
