We will have a limited amount of stock available to ship mid to late June.
Upgrade your MX-5 NC fuel system with our aluminium fuel tank top hat, designed to replace the restrictive factory plastic unit and enable the use of a proper fuel return system.
Perfect for turbocharged, supercharged and high-power applications where stable fuel pressure, improved fuel temperature control and aftermarket fuel system compatibility are essential.
Unlike the OEM dead-head arrangement, this top hat allows excess fuel to circulate back to the tank, helping reduce fuel temperature build-up and improving consistency under prolonged hard driving and track use.
Made from laser-cut aluminium and finished in our signature Performance Delta green anodising, this top hat is engineered for reliability, serviceability and motorsport use.
