Nitrous Nozzles, Fogger & Direct Port by Nitrous Express

What Nitrous Nozzles Cover

A nitrous nozzle meters and directs nitrous oxide, and on wet systems fuel, into the intake path. The correct style depends on the induction layout, cylinder count, target power level and the nitrous system design.

Dry and Wet Nozzle Layouts

Dry nozzles add nitrous while the engine management system supplies the extra fuel. Wet nozzles introduce nitrous and fuel together, so hose routing, jetting and fuel system capacity must be planned as one system.

Single Nozzle Systems

Single nozzle systems can suit a broad range of intake layouts when installed and jetted correctly. Piranha, Shark, VXL and straight through styles provide different mounting and discharge options for compatible systems.

Thread Size and Fittings

Match the nozzle thread and fitting size to the intake, distribution block and lines being used. A correct tap, clean thread engagement and leak testing are essential before system operation.

Direct Port and Fogger Systems

Direct port systems use one nozzle per cylinder or runner for precise distribution. They are commonly selected for high output drag race and dedicated performance builds where even cylinder delivery matters.

Cylinder Count Packages

Four, six and eight cylinder nozzle packages help align the hardware count with the engine layout. Confirm the intake manifold material, runner access and installation space before selecting a package.

Plate System Service Hardware

Plate systems use a purpose built spacer plate to introduce nitrous and fuel into the intake stream. Replacement fittings, taps and nozzles must match the existing plate system and intended jetting.

Service Before a Race Weekend

Inspect fittings, hoses, solenoids, filters and nozzle passages before each event. Replace damaged hardware and correct leaks before pressurizing the bottle or attempting a pass.

Fueling and Ignition Preparation

Nitrous use requires fuel delivery, ignition timing, plug choice and engine condition to be evaluated together. Work with a qualified tuner and follow the nitrous manufacturer instructions for every system component.

Data Driven Testing

Begin with a conservative, proven configuration and review fuel pressure and engine data after each controlled test. Do not exceed the recommended limits for the engine, fuel system or drivetrain.

How to Choose the Correct Nitrous Nozzle

• Confirm the exact year, make, model, trim, engine and drivetrain
• Identify whether the system is dry, wet, direct port or plate style
• Match the nozzle design to the intake material and available mounting area
• Choose the correct thread size before drilling or tapping
• Match nozzle count to the engine cylinder count for direct port systems
• Confirm fitting, line and solenoid compatibility
• Plan fuel delivery for the intended nitrous power level
• Use recommended jets and installation instructions from the system manufacturer
• Check bottle pressure control and safety equipment before testing
• Have a qualified tuner review the complete engine combination

Common Questions

What does a nitrous nozzle do?

It directs metered nitrous, and on wet systems fuel, into the intake path.

What is the difference between dry and wet nozzles?

Dry systems add nitrous only while wet systems add nitrous and fuel together.

Can I use one nozzle for every engine?

No. Nozzle style, thread size, flow requirements and system design must match the build.

What is a direct port system?

It uses a separate nozzle at each cylinder or intake runner for controlled distribution.

Why does thread size matter?

The nozzle, fitting and tap must share the proper thread specification for a safe sealed installation.

Can I replace only a damaged nozzle fitting?

Yes, if the replacement matches the nozzle family, thread size and line connection.

Should I change jets when installing a new nozzle?

Use the system manufacturer guidance and a qualified tuner to select safe jetting.

Do I need fuel system upgrades for nitrous?

Fuel capacity must support the planned power level, especially on wet systems.

Can nozzles be used on a street vehicle?

They can be used on properly prepared applications that follow local rules and safe operating procedures.

What should I inspect before use?

Inspect lines, fittings, solenoids, bottle pressure, fuel supply and nozzle passages before testing.
