Throttle Body Gaskets

Holley Throttle Body Gaskets (MPN 108-40) are precision-engineered sealing components designed for carburetor and fuel injection throttle body installations. These gaskets are essential for preventing vacuum leaks, which can lead to rough idling and hesitation during acceleration. Whether you're working on a classic carbureted engine or a modern EFI system, these gaskets are crucial for reliable engine performance.

Manufactured to OEM specifications, the Holley 108-40 gaskets are made from materials that can withstand thermal cycling, fuel exposure, and manifold pressure. Their precision-cut edges ensure a tight, repeatable seal without deformation under clamping load, which is vital for maintaining idle stability and driveability in tuned engines. The compact design allows for easy integration into any installation.

Technicians and enthusiasts who are rebuilding Holley carburetors, performing throttle body swaps, or servicing fuel-injected platforms will find these gaskets indispensable for achieving leak-free installations. With Holley's extensive expertise in carburetors and EFI systems, you can trust that these gaskets will meet or exceed OEM performance standards.
