FiTech Nitro-Port Cast Intake Manifolds
FiTech Nitro-Port Series cast intake manifolds are engineered for serious street and strip enthusiasts, providing power, precision, and versatility to LS1 and LS3 platforms. Designed with performance and adaptability in mind, Nitro-Port manifolds feature a low-profile, modular design ideal for tight engine bays while supplying aggressive performance gains. Short runners support high-RPM power, and -8 AN fuel rails with -8 ORB fittings ensure consistent high-flow fuel delivery under demanding conditions.
For those pushing the limits, integrated nitrous/water injection bungs offer easy expandability, while rear-mounted vacuum and pressure ports keep plumbing clean and accessible. These manifolds also include a rear-mounted MAP sensor location for simplified installation. The Nitro-Port accepts 92mm, 102mm, and drive-by-wire throttle bodies with a straight throttle body mounting flange, allowing builders more flexibility across multiple LS configurations.
Whether you're building a high-revving track machine or a show-stopping street car, FiTech Nitro-Port cast manifolds deliver the performance, reliability, and engineering excellence customers expect from FiTech Fuel Injection.
* Models are available for a variety of Chevy engines from 1997 and up.
