Nitrous Express 4150 4-BBL/Alcohol Nitrous Kit (50-300HP) w/o Bottle

This Nitrous Express 4150 4-BBL/Alcohol Nitrous Kit comes with the main nitrous plate, Lightning solenoids with a limited lifetime guarantee, a heavy-duty 40-amp relay, stainless steel bottle brackets, and an extra-long supply line. It's designed for alcohol fuel systems and offers adjustable horsepower gains from 50 to 300 HP, making it a solid option for budget-minded racers looking for an entry-level nitrous system.

The Phase 3 series plate technology is a notable advancement, utilizing a spraybarless design. This means there are no spray bars that can sag, split, or obstruct airflow, which helps ensure consistent fuel distribution and outstanding atomization. This design contributes to improved performance and reliability compared to older spray bar systems. The kit is specifically configured for alcohol fuel, which is common in many racing applications.

Because this is a kit without a bottle, you'll need to source a compatible nitrous bottle and any associated mounting hardware separately. It's also important to note that this system is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and tuning to achieve the desired horsepower gains safely.
