Common Repair Uses

• Vacuum leaks around the intake/throttle body interface
• Idle quality issues related to a compromised seal
• Service replacement after throttle body removal
• Emissions-related sealing concerns on California-only Sentra applications

Installation Notes

Clean both mating surfaces before installation and verify the throttle body and intake flange are free of old gasket material, oil, and carbon buildup. Confirm the vehicle year, model, and emissions configuration before ordering, especially for 2001-2002 Nissan Sentra California-only applications. Match the part number ATB4287 to the vehicle application during service.

Quality Assurance

Apex identifies this part by application-specific fitment for the listed Nissan models. Verify the OE-style sealing surface and vehicle configuration before installation to ensure proper throttle body mounting gasket replacement.
