Audi CREC 3.0T MPI Injector Upgrade Kit for E85

After extensive R&D, real-world testing, and countless hours refining the CREC platform, Jackal Motorsports proudly introduces the CREC 3.0T MPI Injector Upgrade Kit — a purpose-built fueling solution designed to give Audi 3.0T owners the safe fueling headroom required for full Stage 2+ E85 performance.

This system was developed specifically for the Audi CREC 3.0T engine and is the first injector solution engineered to support aggressive ethanol tuning while maintaining stable fueling under high load.

The fastest known CREC cars are currently running Jackal , all powered by our Stage 2+ E85 calibrations, and this injector upgrade is a key part of that formula, and we’re only getting started.

The Jackal CREC 3.0T MPI Solution

First-to-market fueling upgrade for the CREC platform

The Jackal CREC MPI Injector Upgrade Kit was designed specifically for the Audi 3.0T MPI system to deliver reliable, high-flow fueling for ethanol-based tuning.

Unlike generic injector upgrades, this kit was engineered around the fuel demands of the CREC engine running high-ethanol blends, ensuring stable fuel delivery during aggressive pulls and sustained high load.

Real results — not dyno sheet hype

This system was developed and validated on real cars driven on real streets.

Our development vehicles have consistently produced repeatable 10-second quarter

mile passes on Stage 2+ E85, demonstrating the capability of the Jackal fueling and calibration strategy. No inflated horsepower numbers — just proven performance and consistent results.

Continuous development

Jackal’s CREC platform development is ongoing.

Through extensive internal testing, customer feedback, and continuous calibration refinement, we’re constantly improving performance, reliability, and drivability for the Audi 3.0T community.

Why the Audi CREC 3.0T Needs MPI Injectors for E85

Running full E85 on the Audi CREC 3.0T engine dramatically increases fuel demand compared to pump gas.

The factory direct injection system alone does not provide enough fueling capacity to safely support aggressive Stage 2+ ethanol tuning.

By supplementing the system with high-flow MPI injectors, additional fuel can be delivered under boost while maintaining stable pressure and proper air-fuel ratios.

The result is:

safer fueling margins
improved high-load fueling stability
greater tuning flexibility for high-ethanol blends
the ability to support significantly higher power levels

Complete Fuel System Approach (Required for Stage 2+ E85)

For reliable Stage 2+ E85 performance, the MPI injector kit must be paired with supporting fuel system upgrades.

The Jackal fueling strategy requires the following components:

Jackal MPI line upgrade
Dual El-Doc low-pressure fuel pump (LPFP)

These components work together to ensure:

stable low-pressure fuel supply
consistent injector flow under high load
proper fueling control during ethanol tuning
long-term reliability of the fuel system

What’s Included in the Kit

6 high-flow CREC 3.0T MPI injectors
Optimized for ethanol-rich Stage 2+ calibrations.
4 billet aluminum fuel rail spacers
Designed for correct injector fitment and proper clearance.
4 mounting bolts
Required hardware for installation.

What You’ll Gain

Installing the Jackal CREC MPI Injector Upgrade Kit provides the fueling headroom required to safely run full ethanol calibrations.

Benefits include:

Proper fueling capacity for Stage 2+ E85 tuning
Improved throttle response under boost
Consistent fueling during high-load operation
Increased tuning flexibility for higher power levels
Proven components validated through extensive real-world testing

Most importantly, it provides confidence that your fueling system can safely support the power your tune demands.
