Nitrous Systems for Enhanced Performance & Power

What This Collection Covers

Nitrous systems inject nitrous oxide and additional fuel into the engine to support a temporary, controlled horsepower increase. This collection covers complete kits ready to install, including the solenoids, jetting, and activation wiring needed to add a nitrous shot to a naturally aspirated or forced induction gas engine.

Categories Included

Wet nitrous kits, dry nitrous kits, nitrous plate systems, direct port fogger systems, and EFI specific nitrous kits designed to work with factory or aftermarket fuel injection and ECU tuning.

Wet vs Dry Nitrous Kits

A wet kit introduces nitrous and fuel together through a single nozzle or plate, delivering a simpler installation and more consistent tuning across power levels. A dry kit introduces nitrous only and relies on the factory or aftermarket fuel injectors to supply the extra fuel, which keeps the intake tract cleaner but requires more precise tuning on EFI vehicles.

Choosing Between Wet and Dry Systems

Wet kits are generally the simpler and safer choice for a first time nitrous installation, while dry kits are popular on EFI platforms where tuners want to manage fuel delivery entirely through the injectors and ECU.

Nitrous Plate Systems

Plate systems sit between the intake manifold and throttle body, distributing nitrous and fuel evenly across all cylinders through a purpose built plate. Plate kits are a common choice on carbureted and EFI engines using a single plane or dual plane intake manifold with adequate plenum clearance for the plate.

Plate Fitment Considerations

Plate thickness and bolt pattern must match the intake manifold and throttle body being used, and hood clearance should be checked before installation on engines with a low hood line or aftermarket intake setup.

Direct Port Fogger Systems

Fogger systems inject nitrous and fuel directly into each intake runner near the cylinder head, offering the most precise and highest capacity nitrous delivery for engines built to handle larger shots. Fogger systems are typically used on dedicated race engines and high horsepower builds rather than daily driven street cars.

When to Step Up to a Fogger System

Fogger systems are worth the added installation complexity when a build is targeting nitrous shots beyond what a plate system can safely and evenly distribute, particularly on engines with aftermarket heads and a stronger short block.

How to Choose the Correct Nitrous System

• Confirm the exact year, make, model, trim, and engine before ordering a kit
• Match the kit to the fuel system type, carbureted, port EFI, or direct injection
• Decide between a wet kit for simpler tuning or a dry kit for EFI injector based fuel delivery
• Confirm intake manifold and throttle body compatibility before selecting a plate system
• Choose jetting sized appropriately for the engine build and supporting fuel system capacity
• Verify the bottle, brackets, and purge kit needed are included or must be purchased separately
• Plan for a window switch or blower safety switch on forced induction applications
• Budget for a tune or safe fuel and timing settings anytime a nitrous shot is added or increased

Common Questions

What is the difference between a wet and dry nitrous kit?

A wet kit delivers nitrous and fuel together through the same nozzle or plate, while a dry kit delivers only nitrous and relies on the factory or aftermarket fuel injectors to add the corresponding fuel. Wet kits are generally simpler to tune correctly.

Do I need a tune after installing a nitrous system?

Yes, in most cases. EFI vehicles typically need a tune to adjust fuel and timing to safely support the added nitrous shot, and even carbureted applications benefit from jetting adjustments to avoid running lean under nitrous activation.

Can I use a nitrous system on a forced induction engine?

Yes, many nitrous kits are compatible with turbocharged or supercharged engines, but a boost referenced solenoid or safety switch is strongly recommended to prevent nitrous activation outside of a safe boost window.

How much horsepower does a nitrous kit add?

Nitrous shots are commonly sold in increments from around 50 horsepower up to several hundred horsepower depending on jetting, with most street kits sized in the 75 to 150 horsepower range for a stock or mildly built engine.

What size nitrous bottle do I need?

Bottle size is typically chosen based on how often the vehicle is driven under nitrous and how far the driver travels between refills, with 10 pound bottles common for street use and larger bottles favored for track only vehicles.

Is a plate system or fogger system better for my build?

Plate systems are simpler to install and well suited to street and moderate power builds, while fogger systems distribute nitrous and fuel more precisely per cylinder and are preferred for higher horsepower and dedicated race engines.

Do I need a fuel pump upgrade to run nitrous?

Larger nitrous shots increase fuel demand, so confirm the existing fuel pump and lines can support both the base engine tune and the added nitrous fuel requirement before installing a larger kit.

Is nitrous safe for a daily driven vehicle?

A properly tuned and conservatively jetted nitrous system can be used safely on a daily driven vehicle, but it should be installed with the correct safety switches and only activated under the conditions the system was designed and tuned for.
