Nitrous Kits

How much extra power does your engine need, and how should the nitrous get into it? A nitrous kit typically combines the bottle, solenoids, lines and nozzle or plate in one package, giving you a complete system for your project.

Dry, plate or direct port?

The kits differ in how the nitrous and extra fuel reach the cylinders. In a dry kit, only nitrous is added, and the engine's own fuel injectors have to supply the extra fuel, e.g. in the Nitrous Express Dry EFI Single Nozzle Nitrous Kit (35-150HP). A plate kit typically sits between the throttle body and the intake manifold. Direct port gives each cylinder its own nozzle and therefore a more even distribution. You'll find individual parts among our nitrous nozzles and nitrous bottles.

How to choose a nitrous kit

Consider several factors together:

• Power target: The kits state a range, e.g. 50-400HP, and the specific shot is determined by the jets you install.
• The engine: Pistons, connecting rods and spark plugs must be able to handle the shot. The bigger the boost, the more it depends on how the engine is built.
• Fuel: The pump and injectors must be able to deliver enough fuel so the mixture doesn't run too lean.
• Ignition: Ignition timing typically needs to be retarded when the nitrous is active.

In this category you'll find kits from Nitrous Express and FAST, several of them with a 10 lb bottle.

Installation and maintenance

Check lines, fittings and filters regularly. Also keep an eye on bottle pressure, as it affects how much nitrous is delivered. Whether the kit may be used on the road depends on the product and the car, so check the approval for the specific part number.

Frequently asked questions

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

In a dry kit, only nitrous is added, and the engine's own fuel injectors have to supply the extra fuel. A wet kit adds fuel together with the nitrous through the nozzle or plate. What suits you depends on the fuel system and power target.

Can I drive with a nitrous kit on public roads?

That depends on the product, the car and the applicable regulations. Modifications that increase engine power typically have to be declared and may require an inspection. So check the approval for the specific part number before installing the kit.

Why does the power change when the bottle gets cold?

Bottle pressure drops with temperature, and lower pressure can result in less nitrous relative to fuel. The mixture then becomes richer, and power typically drops. So keep an eye on the pressure and the bottle's temperature.
