Our 74mm Throttle Body gasket is made to fit the K Series Ultra Street Intake Manifold (K20A2 Style, PN 307-05-0605). When using the manifold with our Ultra Street Plenum Spacer and Pro 74mm K-Series Throttle Body, this gasket must be used as it is thicker than our standard gasket and provides additional clearance that is necessary.

New longer hardware is included for ease of installation.

FEATURES:

• Provides Necessary Clearance for Pro 74mm Throttle Body
• Reduces Heat Soak
• Reduces Incoming Air Temperature
• Reduces Heat Transfer Into Intake Manifold
• Includes New Hardware
