4500 Billet Throttle Body 1610CFM

The 4500 Billet Throttle Body 1610CFM from Wilson Manifolds is purpose-built for serious engine builders and performance enthusiasts seeking to maximize airflow and throttle response in high-output applications. This precision-engineered component replaces restrictive OEM throttle bodies, allowing your fuel injection system to deliver fuel more efficiently across the entire RPM range. Whether you're tuning a naturally aspirated stroker, preparing for nitrous oxide injection, or building a twin-turbo platform, the 1610 CFM rating ensures adequate volumetric efficiency for engines producing 400+ horsepower.

Manufactured from premium billet aluminum, this throttle body delivers superior durability and thermal stability compared to cast iron or plastic alternatives. The 1610 CFM flow capacity represents the maximum air volume the throttle plate can pass, measured in cubic feet per minute—a specification that directly correlates to top-end power production and throttle authority. The billet construction allows for tighter tolerances in the bore, reducing air leakage around the throttle shaft and ensuring consistent fuel metering across idle, cruise, and wide-open throttle conditions. At 4.95 lbs and compact dimensions of 8.4 x 4.5 x 8.4 inches, it integrates cleanly into engine bays with minimal packaging compromise.

This Wilson Manifolds throttle body performs best when paired with a quality EFI tune and larger fuel injectors sized to match the increased airflow potential. Street machines, race cars, and engine swap projects all benefit from the improved throttle response and reduced hesitation common when stock throttle bodies become the limiting factor. Installation typically requires custom intake manifold work or adapter plate fabrication, making this component ideal for builders committed to optimizing their breathing architecture. Verify your existing fuel delivery system and ECU capability before selecting this 1610 CFM unit to ensure your injectors and tuning can support maximum flow demand.
