Evolution of Speed – N55 Intake Manifold

Evolution of Speed Port Injection Spacer Kits for the N54 are now available.

Evolution of Speed is proud to bring our N55 intake manifold to market. This is the best way to add port injection to your E or F Series N55 powered BMW. This intake manifold was built for the serious enthusiast looking for a sleek way to increase fueling capability while increasing plenum volume and the ability to port match intake runners on built cylinder heads.

The manifold can be ordered in the Base form, which includes injector plugs, or with fueling that includes basic fuel hook up and injectors. You can also order the fueling option without injectors, which allows you to provide your own injectors, but still comes with basic fuel hookup. Be sure to select your injector size!

***If you select Base as an option you cannot add injectors, it will show as out of stock. Injectors can only be added if you select the fueling kit, which can be ordered with and without injectors****
