About this part

Product Details

If you're looking to add significant horsepower to your vehicle with a nitrous system, this Covert Crossbar plate conversion kit from Nitrous Express is a serious upgrade. Designed for 4500 flange carburetors, this kit is capable of supporting anywhere from 50 to 300 horsepower, making it suitable for a wide range of performance builds. The core of this system is its advanced billet crossbar design, which moves away from traditional spray bars.

This CNC machined crossbar design is a notable step forward in nitrous plate technology. By eliminating the round spray bars, it ensures excellent atomization of the nitrous and fuel mixture, leading to better cylinder distribution and more consistent power delivery. Without spray bars that can sag, rotate, or disrupt airflow, this plate offers a cleaner path for the intake charge, contributing to improved overall engine performance. This conversion kit comes with everything you need to get started, including a custom solenoid bracket, braided stainless steel lines connecting the solenoid to the plate, stainless steel fittings, a full set of nitrous and fuel jets to tune your desired horsepower level, and longer carburetor studs for proper installation.

This kit is a conversion, meaning it's designed to integrate with your existing nitrous system components. It's important to note that this product is not CARB approved and cannot be shipped to California due to emissions regulations. Always refer to the manufacturer's installation instructions for proper setup and tuning to ensure safe and effective operation.
