What do I need to install an aftermarket EFI system?
u003cstrongu003eA:u003c/strongu003e An EFI system can come with most of what you need to bolt it on. Some kits might even come with ignition and fuel system components. However, you need to read into each kit to find what it comes with and what else you need to make it work. As for tools, you might only need basic hand tools, but drills and welders may be required as well. Again, it depends on the kit you’re working with.
