90mm LS Throttle Body w/Tapered Bore - Black

The 90mm LS Throttle Body w/Tapered Bore from HOLLEY is a precision-engineered intake component designed specifically for GM LS-series engines. This throttle body is ideal for both high-performance and modified applications, catering to enthusiasts and professionals who require reliable fuel delivery control. It serves as a critical interface between the intake manifold and fuel injection system, ensuring consistent air metering across the full RPM range.

Constructed from high-grade aluminum and finished in black anodize, the 90mm LS Throttle Body is designed for durability and corrosion resistance. Its tapered bore design promotes smooth air acceleration and reduces turbulence within the intake tract. The single-blade configuration allows for precise throttle modulation, while the 4-bolt stock flange enables direct installation onto compatible LS intake manifolds without the need for adapter plates or modifications.

This throttle body is particularly beneficial for those upgrading from a stock unit or integrating it into a custom LS platform build. It addresses the need for improved throttle linearity and response in both street and competition environments. The tapered geometry optimizes flow characteristics across all load conditions, making it suitable for both naturally aspirated and forced-induction setups.
