105mm Throttle Body - 1520CFM 4.250 OD

The Wilson Manifolds 105mm Throttle Body – 1520 CFM 4.250 OD is designed for high-performance EFI and forced induction applications, where precise air delivery is crucial for maximizing horsepower and throttle response. This throttle body is ideal for serious street and competition engine builds, ensuring optimal drivability and performance.

Engineered with a 4.250-inch outside diameter flange, this throttle body maintains compatibility with modern intake manifold bolt patterns while providing structural rigidity under boost or high-RPM conditions. The 105mm bore diameter is optimized for airflow, generating strong signal strength for fuel injection tuning while preventing excessive fuel film washdown at wide-open throttle.

This throttle body is particularly beneficial for high-displacement engines and supercharged applications, where precise fuel metering and air control are essential. Weighing just 2.4 pounds and with compact dimensions, it allows for straightforward installation in tight engine bays without extensive custom fabrication.
