Pontiac SD Intake Gasket 1.90in x 2.70in SPREAD

The FEL-PRO Pontiac SD Intake Gasket 1.90in x 2.70in Spread Port is an OEM-quality replacement gasket specifically designed for select Pontiac SD block engines that require precise intake manifold sealing. This gasket plays a critical role in preventing coolant and combustion gas leakage between the intake manifold and cylinder head, which is essential for optimal engine performance and reliability.

Manufactured to factory specifications, this gasket utilizes advanced elastomer compounds and precise die-cutting to achieve the exact 1.90-inch by 2.70-inch spread port dimensions that match Pontiac SD cylinder head geometry. Its composition is designed to resist thermal cycling, coolant degradation, and combustion pressure, which are critical factors in an engine bay where temperatures can exceed 200 degrees Fahrenheit.

Engine builders and mechanics working on second-generation Pontiac powerplants will find this gasket to be the correct specification for SD block applications. Whether diagnosing coolant leaks around the intake manifold or performing a complete head gasket service, using the correct FEL-PRO part number 1249 ensures that seal integrity is maintained, preventing mismatches that could lead to engine issues.
