Gasket - GM LS Throttle Body 105mm

The Gasket - GM LS Throttle Body 105mm (HLY508-24) is an essential sealing component designed for LS-platform intake manifold builds and throttle body installations. This precision gasket ensures a tight seal between the 105mm throttle body and the intake manifold, effectively preventing vacuum leaks that can negatively impact idle quality, fuel economy, and engine control system stability.

Manufactured by Holley, a reputable name in LS performance and fuel delivery systems, this gasket is built to withstand the thermal cycling and pressures associated with modern LS engines. The 105mm bore is compatible with both OEM and aftermarket throttle bodies, ensuring a reliable seal that does not hinder airflow or throttle response. Proper gasket selection is crucial to avoid hidden air leaks that can lead to rough idling, hesitation, and check engine lights.

This gasket is particularly beneficial for LS platform builders engaged in throttle body manifold combinations, including street engines, crate motor installs, and performance swaps into non-LS platforms. Installation is straightforward, requiring the gasket to be positioned between the throttle body and manifold for a secure fit.
