LS7 Intake Manifold - LSXR 102mm

The LS7 Intake Manifold with LSXR 102mm throttle body flange is a raised-port, multi-port design engineered for the GM LS-series engine platform. This black plastic manifold represents OEM-level intake architecture, optimizing air charge density and fuel atomization across the entire RPM band. The 102mm throttle body flange accommodates modern fuel-injection and variable-geometry air management systems while maintaining port alignment with LS7 cylinder head specifications.

The raised-rectangle port geometry is critical for flow characteristics in the mid-to-high RPM range where volumetric efficiency directly impacts horsepower output. The multi-port configuration distributes fuel and air evenly across all cylinders, reducing combustion variance and emissions scatter. At 20.37 pounds, the manifold carries minimal parasitic weight while maintaining structural rigidity under boost or high-load conditions. The plastic construction resists corrosion in moisture-heavy environments and provides thermal isolation between the charge air and engine block—a key factor in maintaining cooler intake temperatures under sustained high-RPM operation.

This manifold is designed for LS-series engine builders and restoration shops working with Gen III, Gen IV, or LS7 platforms. Whether building a naturally aspirated performance engine, a supercharged street application, or a turbocharged track car, proper intake manifold selection determines baseline efficiency before any fuel mapping or boost calibration occurs. The LSXR designation signals compatibility with modern LS variants, making this the correct choice for contemporary LS-series builds.

GM LS-series platforms have dominated performance and racing applications for two decades because they respond predictably to bolt-on modifications when each component—from manifold to fuel system to induction—is properly matched. The LS7 Intake Manifold ensures the intake tract is optimized before dyno testing or track use, eliminating a common weak link in budget builds.
