#1. FiTech GO EFI 4 Fuel Injection System
When it comes to the best fuel injection system, we have to recommend the FiTech GO EFI 4. It is rated at 600hp but great for all engines from 200 HP all the way to 650 HP.
Perhaps its best feature and the one that separates it from the rest of the competition is the fact that it features the fastest and most accurate self-learning in the market.
It also fits any 4-bbl intake manifold and is the most self-contained and full-featured unit of this type. And installation is easy given the ECU is mounted on the throttle body. Additionally, it also offers spark control without the need for an external spark box or special distributor, which is quite rare. Furthermore, we really like the built-in fuel pressure regulator.
#2. Holley Black Sniper EFI Fuel Injection System
Next up we have the Holley Black Sniper EFI Fuel Injection System, which is the best fuel injection system for those who want a full master kit. It supports up to 650 HP to 1250 HP. The 650 HP is the 4 injector version while the 1250 HP is the 8 injector version. This gadget really stands out in our opinion because it is a self-tuning, plug-and-play fuel injection system.
So basically it has a self-learning ECU that pretty much sets the baseline tune. If you want to fine-tune as you go, you can always just use the full touchscreen display. And finally, we just want to say that you can fully trust this fuel injection system to work as Holley Sniper has been in the industry for over 100 years and is very reliable.
#3. FAST Fuel Injection System
Another great option when it comes to the best fuel injection system is the FAST Fuel Injection System. It includes an ECU, wiring harness, fuel injectors, wide-band oxygen sensor, fuel pump kit, and throttle body. This fuel injection system will bolt to basically any naturally aspirated engine up to 600 horsepower and up to 60 psi. It works with the original carb-style throttle linkage and accepts all OEM sensors.
Overall, the self-tuning works great and the kit is pretty easy to install. While we do recognize that there are some people who have had bad experiences with it, we certainly did not. Just know that there has been plenty of research on this system and it has been tested countless times before finalizing and being sold to you.
#4. ACDelco Fuel Injector Kit
The ACDelco Fuel Injector Kit is pretty solid in that it is literally a GM-recommended replacement for your vehicle’s original component. It is manufactured to GM’s OEM specifications and has all of the quality, durability, reliability, and trust built right into it. And best of all, this fuel injector kit is cheap compared to our previous recs.
With this kit installed, you should have no problem getting better start-ups with your engine running much better. Your misfires will be gone and your catalytic converters will be quiet. The only thing we ask is that you don’t get your hopes up since this is not one of those EFI complete kits to be placed on a race car to enhance its performance.
#5. Fitech Fuel Injection Go Street
Lastly, on our list, we recommend the Fitech Fuel Injection Go Street. This is Fitech’s answer for those who don’t have 600 HP or a wild camshaft. This product is for those who have a ZZ4 crate engine or just a normal factory engine and yet want to reap all the benefits of EFI.
This is a ready-to-run system that gives you the basics that you need to get the best performance and economy out of your stock engine. It will also help you ditch that old carb. You can look up the specs in the link below and check out other recommendations. Or you can just trust us and remember that this is the best EFI system for normal cars.
