The GM 12480048 Racing SB2 Intake Manifold is a high-performance aftermarket intake manifold designed for select GM applications. This intake manifold is engineered to deliver enhanced engine breathing, improved airflow, and increased power and torque.
The Racing SB2 Intake Manifold is constructed from aluminum, which not only reduces the weight of the manifold but also aids in better heat dissipation compared to stock cast iron intake manifolds. This intake system features a two-piece design, allowing easy access to the engine for maintenance and modification.
With a larger plenum volume and smoother, more efficient airflow, this intake manifold maximizes power output from the engine. The runners on the Racing SB2 Manifold have been designed and optimized using advanced CAD software and flow bench testing to ensure peak performance.
The intake manifold also comes with EOM (Electric Over Manifold)PORT technology. This innovative feature allows the throttle body to be moved away from the intake runners during "idle" conditions, resulting in improved idle stability, enhanced cold start performance, and significantly reduced exhaust gas recirculation.
Additionally, this intake manifold comes with 85mm throttle bodies which offer larger intake valves allowing for more airflow to the combustion chamber, increasing power and enabling better engine response. The throttle bodies have quiet, self-lubricating bearings to ensure smooth operation and extremely low vibration levels.
This high-performance intake manifold is designed to be a direct replacement for factory intake systems, making for an easy installation. All required hardware, gaskets, and instructions come included with the intake manifold, simplifying the installation process.
By upgrading your factory intake manifold with the GM 12480048 Racing SB2 Intake Manifold, you can expect improved airflow, increased power and torque, and better engine response. This intake manifold is an essential upgrade for any serious performance enthusiast seeking to elevate the power and efficiency of their GM engine.
The GM 12480048 Racing SB2 Intake Manifold is a performance upgrade designed for some General Motors engines. Here are the potential advantages and disadvantages of investing in this aftermarket part.
Pros:1. Improved Airflow: The Racing SB2 Intake Manifold is designed to increase airflow into the engine, allowing for better fuel combustion. This leads to increased horsepower and torque, resulting in better engine performance.
