What components are included in this water injection kit?

This kit includes a pressurized reservoir, a pressure regulator, braided stainless steel AN hoses, billet distribution blocks, filtered nozzles, and nickel-plated fittings. It is designed for 8-cylinder engines and does not require a separate electric pump.

Why is direct port injection beneficial?

Direct port injection delivers the water-methanol mixture directly into each intake runner. This ensures a more even distribution to every cylinder, leading to more consistent charge cooling and detonation suppression across the engine.

Are there any restrictions on where this kit can be shipped?

Yes, this system is not CARB approved and cannot be shipped to California due to emissions regulations.

About this part

Product Details

With this Nitrous Express Pumpless Direct Port Water Injection system, you get everything you need to inject a water-methanol mixture directly into each intake runner for an 8-cylinder engine. This setup ensures excellent distribution to every cylinder, which is key for consistent performance and engine protection under boost. The system includes a pressurized reservoir and a pressure regulator, meaning you don't need a separate electric pump to get the mixture flowing. This design simplifies installation and reduces potential points of failure.

You'll find high-quality components throughout this kit. It comes with braided stainless steel AN hoses for durable and leak-free connections, along with billet distribution blocks that are built to last. The filtered nozzles help prevent clogging, ensuring a steady spray pattern, and all the fittings are nickel-plated for corrosion resistance. This direct port setup is designed for maximum effectiveness, delivering the water-methanol mixture right where it's needed most for optimal charge cooling and detonation suppression.

This system is a solid option for serious tuners looking to push their forced induction setups further. Remember that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and tuning.
