One misconception we keep seeing about AuxJection is that it sprays fuel ALL the time.

It does not.

AuxJection is not just sitting there constantly dumping fuel into the supercharger during idle, cruising, light throttle, or normal driving.

The system is integrated into the OEM software and is commanded when additional fuel is actually needed. That means the auxiliary injectors are there to support the setup under higher demand when the direct injection system can no longer maintain the required fuel volume, not to run nonstop every time the engine is on.

Think of it like added injector capacity.

It is available when the combination needs it, but it is not spraying just because the car is running.

That is a big part of why the tuning process stays clean and why the system works the way it does. AuxJection was designed to supplement the factory fuel system in a controlled, calculated way, not act like an uncontrolled fuel dump.

Idle, cruise, and normal driving? Not spraying.

Higher load and fuel demand when the direct injection system has reached its limit?

➞ That is where AuxJection comes in.

There are a lot of misunderstandings out there, so we’re going to keep explaining how the system actually works.

Let's talk about a massive benefit of AuxJection that isn't just about fuel volume: a 40°F drop in supercharger discharge temps.

When you think about adding a secondary fueling system, you're usually just looking to feed a hungry engine. But introducing fuel at the supercharger snout gives you an incredible secondary win that every supercharged setup needs.

Because the fuel atomizes right as it passes through the rotors, it actively absorbs heat.

The data proves it:

- Over a 40°F peak drop in supercharger rotor discharge temperatures.
- Exceptional cooling across the entire blower.
- A direct correlation to the repeatable, solid power increases seen in our testing results.

If you’re fighting high air temperatures, pulling timing on hot days, or pushing your blower past its efficiency zone, solving your fueling bottleneck can completely change your intake temps at the exact same time.
