Nitrous Express is now offering popular intake manifolds that are pre-plumbed with NX nitrous systems. These intakes are brand new and installations have been completed by the technicians at NX so you can simply pull the intake out of the box and install it on your engine. Each component of the nitrous system has been inspected upon installation and the entire setup has been leak checked and flow tested. Many popular intakes are in stock and ready to ship immediately while other applications are available via special order.
