Product Description

Fuel Injector Pro - Fuel System & Injector Cleaner

We have a secret, a dirty secret. But we also have the clean solution that won’t break the bank and will give your car the love it deserves.

Shhh. We Have a Secret…

Think about your car for a moment. Although it might look clean and polished on the outside, on the inside it's dirty. Especially in new GDI engines. 

Fuel injectors get so dirty, so fast, you can actually start feeling their poor performance within 10,000 miles. Leave these injectors untreated and next thing you know, you are stuck with a slow, shaking car that doesn’t go like it used to.

Sounds like a complicated problem, right? Well, our chemists don’t back down from a challenge. We know what it takes to formulate and innovate technology others can’t and that's why 104+ Fuel Injector Pro is the ultimate fuel system and injector cleaning solution. 

What is GDI?

Have you heard of GDI engines before? Why do we have this technology?

Well, ultimately it means better engine performance but high performance can come at a price. That price is carbon deposits and not just any carbon deposits!

Because the injector is housed directly in the combustion chamber we're talking about heavy, hard, caked-on solid carbon deposits. So tough to clean, we don’t know of any other fuel system cleaner that actually works, which is why we formulated 104+ Fuel Injector Pro.

Why Fuel Injector Pro?


No carbon deposits means better fuel system operation, which equals better engine performance like faster throttle response, smoother idle, and better fuel economy.

Not only do you get better fuel economy, you will save money not taking your car to the shop to have your fuel system flushed.


Fuel systems flushes can cost upwards to $250! And GDI engines get dirtier faster which means more money out of your pocket.

GDI Engines can start losing efficiency in as little as 7,000 miles. Why let your vehicle get the best of you? Be proactive with 104+ Fuel Injector Pro and save in the long run.

104+ Originality

Since 1975, 104+ has been a brand driven to provide your car with superior performance.

From 104+ Octane Boost to the new, ground-breaking fuel system cleaning technology in 104+ Fuel Injector Pro, 104+ is always going to be ahead of the game when it comes to treating your car like a superstar.

Fuel Injector Pro is not your typical fuel system cleaner. It is proven to make you “Feel the Difference”.
