The Nitrous Works Custom Plenum Bar Systems

Product images may differ from actual product appearance.

Plenum bars offer superior distribution over a plate and are most popularly used in conjunction with a direct port system for multiple stage applications. By installing the spray bars in the plenum of the intake, the nitrous and fuel discharge is moved closer and better aligned with the entry to each port runner. Single stage plenum bars up to 400 horsepower can be installed in single four barrel manifolds. Single, dual, and split plenum bar configurations can be custom installed in most tunnel ram manifolds.
