Why Industrial Injection

WHEN FACTORY
FUEL COMPONENTS
ARE THE LIMIT.

At Stage 2 power on most platforms, the factory fuel system components are adequate. At Stage 3 — compound turbo, big injectors, high-fueling competition tune — the factory components become the bottleneck. That's when the conversation shifts to Industrial Injection.

Industrial Injection has been making diesel fuel system components for over 30 years — upgraded injectors, CP3 high-pressure injection pumps, compound turbo manifolds, and the hardware that connects those systems together. Their injectors are built from new OEM cores, not cores pulled from the field, which matters for consistency and longevity on a build designed to run hard.

We stock and install Industrial Injection injectors as our preferred upgrade path on Cummins and Duramax Stage 3 builds. On Cummins trucks going into CP3 conversion territory — 2019+ Ram 2500/3500 with a factory CP4 — Industrial Injection CP3 kits are what we run. On Duramax compound builds, their turbo manifolds and compound hardware is the foundation of the turbo system.

The brand isn't a preference — it's a product line that fits the builds we do. If you're asking what injectors go in your compound Cummins, the answer is Industrial Injection. See the fuel system upgrades page for where II components fit in the full fuel system build path.

The II product lines we carry and install on Houston diesel builds — listed by what they do, not by catalog number.

Fuel Delivery
Upgraded Injectors
Stage 2, 30% over, 60% over, and competition injectors for Cummins and Duramax platforms. II injectors are built from new OEM cores with upgraded nozzles and internal components. The nozzle size is matched to the tune and turbo configuration — installing injectors without a matching tune is how you get smoke, not power.
Cummins 5.9 Cummins 6.7 Duramax LBZ Duramax LML
Injection Pump
CP3 Conversion Kits
CP4-to-CP3 conversion kits for 2019+ Cummins and CP4-equipped Power Stroke platforms. II CP3 conversion kits include the CP3 pump, mounting hardware, and fuel line adapters necessary to complete the swap without fabrication. The CP3 is a gear-driven pump with a dramatically better failure mode than the CP4 — the correct solution for high-output tuned trucks.
Cummins 6.7 2019+ Power Stroke 6.7
Turbo System
Compound Turbo Manifolds
Compound turbo mounting manifolds and hardware for Cummins 5.9/6.7 platforms — the foundation of an S300/S400 or S300/S480 compound setup. II compound manifolds are cast from ductile iron and designed for the Cummins exhaust outlet bolt pattern. Includes the primary turbo mounting position and the crossover pipe mounting points for the secondary.
Cummins 5.9 Cummins 6.7
Fuel Lines
High-Pressure Fuel Lines
Stainless braided high-pressure fuel lines for upgraded injection setups — the factory fuel lines are not rated for the pressure output of a Stage 3 CP3 system on a compound turbo build. II stainless lines replace the plastic-jacketed factory supply lines where they're at risk. Pressure ratings match or exceed the CP3 output range.
Cummins 6.7 Duramax LBZ/LML
Injector Service
Injector Remanufacturing
II remanufactured injectors for budget-conscious fuel system refreshes — core exchange program where failed or worn injectors are replaced with II reman units. Reman injectors are rebuilt to factory spec or slightly above. On Cummins trucks where the goal is reliability rather than competition output, reman injectors are a cost-effective path.
Cummins 5.9 Cummins 6.7 Duramax
Power Stroke
6.0 PS Injector Upgrades
The 6.0 Power Stroke injector is a different design than Cummins and Duramax units — a HEUI (hydraulically actuated electronically controlled) system that responds differently to fueling changes. II makes Stage 1 and Stage 2 injector upgrades for the 6.0 PS for shops doing performance builds alongside the reliability package. Not a common application for us, but available.

By Platform

Industrial Injection Components by Platform

Which II products apply to each diesel platform — matched to the build stage where they make sense.

Cummins 6.7
Ram 2500 / 3500 · 2007–Present
  • CP3 Conversion Kit — 2019+ trucks with factory CP4; mandatory before Stage 3
  • 30% Over Injectors — Stage 2 street builds; within EFI Live tune range
  • 60% Over Injectors — Stage 3 compound builds; tune required
  • Compound Manifold — S300/S480 compound turbo foundation
  • HP Fuel Lines — Stage 3 compound with upgraded CP3
Duramax LBZ/LML
Silverado / Sierra 2500 · 2006–2016
  • 30% Over Injectors — Stage 2/3 builds; EFI Live matched
  • 60% Over Injectors — Stage 3 compound builds; full fuel system required
  • Reman Injectors — reliability refresh on high-mileage LBZ/LML
  • HP Fuel Lines — Stage 3 builds above factory line pressure rating
6.7 Power Stroke
F-250 / F-350 · 2011–Present
  • CP3 Conversion Kit — 2019+ trucks; factory CP4 replacement
  • Stage 2 Injectors — HP Tuners Stage 3 builds beyond stock injector range
  • HP Fuel Lines — high-pressure supply lines for upgraded injection
  • Note: Power Stroke injectors are Bosch piezo design — II Power Stroke products are more limited than their Cummins/Duramax line
Common Questions

Industrial Injection FAQ

Questions about II components, injector sizing, and how they fit into the build process.

How do I know what size Industrial Injection injectors I need?+
Injector sizing is determined by the turbo configuration and the tune target, not by a preference or a stage label. A 30% over injector on a single turbo Stage 2 build is matched to a different fueling curve than a 30% over injector on the secondary stage of a compound setup. We size injectors after the turbo configuration and power target are established — not before. Injectors bought without a matching tune produce smoke, not power. We don't sell II injectors without the full build context established first.
What is the difference between II new-build and remanufactured injectors?+
Industrial Injection's performance injectors are built from new OEM cores with upgraded nozzle and tip components. Their remanufactured injectors use field-pulled cores that are disassembled, cleaned, inspected, and rebuilt to factory or slightly above-factory spec. For performance builds targeting Stage 3 or competition output, new-build II injectors are the right choice — consistent cores, consistent spray patterns, predictable fueling behavior. Reman injectors are appropriate for reliability refreshes on trucks returning to stock or Stage 1 power levels.
Does the CP3 conversion kit include everything needed for the swap?+
Industrial Injection CP3 conversion kits for 2019+ Cummins include the CP3 pump, all required mounting hardware, fuel line adapters, and installation hardware. The installation also requires a FASS or AirDog lift pump — the CP3's inlet demand requires a frame-mounted lift pump to maintain consistent positive pressure. That lift pump is not included in the II kit and is a separate item. We bundle the II CP3 kit, the lift pump, and the installation labor as a complete fuel system package — not as separate line items to be ordered and assembled by the customer.
Can Industrial Injection injectors be installed without a tune?+
Technically yes, but the result is not useful. Upgraded injectors installed without a matching tune produce excessive fueling at idle and part throttle — you'll see smoke and lower fuel economy, not more power. The ECM's factory fuel maps are calibrated for stock injector flow rates. When you install a 30% or 60% over injector, the ECM still commands the same fuel duration it would for a stock injector — but now 30% or 60% more fuel is flowing for that duration. The tune recalibrates fuel tables to match the injector's flow rate. We install II injectors and the matching EFI Live or HP Tuners tune as a package. See the engine tuning page for how the tune and injector sizing relate.
