Gasket - Throttle Body Flange 90mm XT

The Gasket – Throttle Body Flange 90mm XT is a composite replacement gasket engineered for the Edelbrock XT throttle body platform. This component seals the critical interface between the throttle body and intake manifold flange, preventing vacuum leaks that would otherwise cause rough idle conditions, hesitation, and elevated emissions readings.

At 90mm bore diameter, this gasket matches the Edelbrock XT throttle body specification exactly, ensuring proper fitment and consistent sealing surface pressure across the flange interface. The composite construction provides reliable durability across temperature cycling and fuel system exposure, resisting degradation that can occur with inferior gasket materials. Proper sealing at the throttle body flange is essential for maintaining accurate air-fuel metering and stable idle quality, particularly in tuned engine applications where vacuum integrity directly impacts drivability.

This gasket serves engine builders, performance tuners, and technicians performing Edelbrock XT throttle body installation or replacement. Whether during initial assembly or routine maintenance, a quality throttle body gasket prevents the vacuum leaks that create diagnostic challenges and poor running conditions. Each gasket is sold individually, allowing for complete system refresh or targeted replacement without unnecessary overstocking.

The 90mm throttle body size represents the mid-range displacement platform common in street performance and stock-displacement applications requiring responsive throttle response without excessive CFM flow. This gasket maintains the OEM-equivalent sealing standard required for proper Edelbrock XT function and long-term reliability.
