* Average 30 hp gain between 5,000 and 7,500 rpm over competitors' high-ram intake manifolds
* Rated for up to 45 psi of continuous pressure
* Compound fuel injector angle aims spray pattern for ideal atomization, resulting in maximum power production and superior drivability
* Reversible top allows for forward- or firewall-facing throttle body installations
* Two nitrous nozzle bosses per runner for clean and easy direct port system installations
