VMP Mustang S550 Engine Coolant Degas Bottle Kit - '15-'23 Mustang

S550 Mustang Degas Bottle (2015–2023)

Tired of the bulky, discolored factory coolant reservoir cluttering up your engine bay? Upgrade to our sleek aftermarket degas bottle designed specifically for all 2015–2023 Mustangs—including EcoBoost, V6, GT, Mach 1, Bullitt, GT350, and GT500 models.

This compact replacement not only cleans up the look under the hood, but also makes trackside maintenance easier. Whether you’re swapping belts, checking connections, or simply showing off your build, the reduced size and clean design give you more space to work while keeping everything fully functional.

• Direct Fit: Works with all factory hoses and connections. 
   
• Factory Cap Compatible: Reuse your stock or decorative coolant cap. 
   
• Quick Connect Included: Comes with the fittings, bolts, and clamps you need for an easy install. 
   
• Durable Finish: Textured black surface hides tooling marks and maintains a consistent, OEM-quality appearance. 
   

Developed using 3D CAD design, 3D printed prototypes, and refined through real-world testing, this degas bottle is the perfect blend of form and function. It’s about making your engine bay look as good as the power you’ve built underneath.

Upgrade your Mustang’s engine bay today with a cleaner, more functional degas bottle.
