If you're looking to upgrade your Lotus Exige with a high-volume fuel rail, the Radium Engineering Fuel Rail Kit is a fantastic choice! Designed specifically for the 2ZZ-GE engines, this kit seamlessly fits your vehicle, ensuring that you can maximize performance without any hassle.
This innovative design takes into account the unique layout of the Lotus Exige-S and 2-Eleven, allowing it to clear the intercooler mounting boss effortlessly. You won't have to worry about compatibility issues here!
Crafted from billet aluminum, this fuel rail is not only sturdy but also features a burnished finish that removes sharp edges while giving it an industrial look. The anodized surface adds an extra layer of corrosion resistance, ensuring that your investment stands the test of time.
Both ends of the rail are tapped to a common 3/4-16 (-8AN) female thread, and the use of positive o-ring seals means no more worrying about damaging aluminum threads or fuel leaks. With the right fitting, adapting to -6AN, -8AN, -10AN, or -12AN fuel lines is a breeze (a -6AN adapter is included!). Plus, the newly added center port accommodates the OEM 2ZZ-GE fuel rail's pulse damper (not included), which helps smooth out pressure fluctuations caused by the fuel injectors.
This aftermarket configuration is ideal for building a high-flow fuel system with aftermarket pumps, hoses, and fittings. Please note that it doesn't include a feed hose, but it does come with a -6AN male adapter fitting and a 3/4"-16 plug for the fuel rail end ports. For the best results, professional installation is recommended when creating a custom fuel system.
