Description

The new dual stage billet plate conversion kits from Nitrous Express have just raised the bar in nitrous plate technology! The CNC-machined design of the billet crossbar plate will eliminate round spray bars, which results in excellent atomization and cylinder distribution. With no spray bars to sag, rotate, or disrupt airflow, this Nitrous billet crossbar nitrous plate system is truly the next generation in crossbar nitrous plate technology.

Conversion kit includes:

* Billet aluminum crossbar nitrous plate
* Stainless braided lines and fittings
* Custom solenoid bracket
* Nitrous/fuel jets
* Longer carb studs
* Carburetor to plate gaskets
