Hidden Crossbar Plate Only 4500 Nitrous Express NX NP613C

This innovative nitrous plate offers all the advantages of Nitrous Express' renowned Billet Crossbar, but with a revolutionary twist.

Stealth Installation

Unlike traditional nitrous plate systems, the Covert Crossbar installs discreetly INSIDE the intake manifold, rather than on top of it. This unique design means you no longer need to invest in costly hoods or modify your existing one. The Covert Crossbar plate allows for a completely hidden nitrous system, with the nitrous and fuel inlets strategically located on the back of the plate, pointing towards the firewall for maximum discretion.

Precision Engineering

While installation does require machining the intake manifold, Nitrous Express takes the guesswork out of it. We provide comprehensive instructions to guide you through the machining process. We also offer a convenient plate machining and installation service for those seeking professional assistance for an additional $200.

Unmatched Distribution

The Covert Crossbar ensures optimal nitrous and fuel distribution and atomization, delivering consistent and powerful results every time. NX Crossbar nitrous plates feature a meticulously designed spray pattern that ensures a precise blend of nitrous and fuel is injected into the runners. This precise distribution provides a more uniform mixture to each cylinder, resulting in enhanced combustion efficiency and peak horsepower.

Key Features:

Covert Design: The plate sits under the carburetor, eliminating the need for hood modifications and remaining out of sight. Nitrous and fuel inlets are located on the back of the plate, pointing towards the firewall.

Optional Installation Service: We offer professional machining and plate installation for $200 (price may vary if your intake requires welding), or we include detailed instructions for machining your intake manifold.

Uncompromising Performance: Delivers the same power and reliability as our standard Billet Crossbar systems.
