Detailed Description

The Standard Ignition PG99 fuel injection plenum gasket is engineered for intake sealing service where the plenum and manifold surfaces must align correctly to prevent leaks. Its construction supports consistent sealing under high heat, while the oil-resistant material helps resist deterioration in the intake environment. This part cross-references 1G1173 and 800-8605 for the same application.

• Rough idle caused by compromised intake sealing
• Vacuum loss related to gasket deterioration
• Oil contamination affecting gasket material performance
• Heat-related sealing breakdown in the intake assembly

Installation Notes and Tips

Clean both mating surfaces thoroughly before installation and verify that the plenum and manifold surfaces are free of old gasket material, oil, and debris. Confirm the correct application by year, make, model, and position before assembly. For best results, follow the vehicle service procedure for intake component removal and torque sequence.
