Detailed Description

Fel-Pro 61343 is a fuel injection throttle body mounting gasket engineered for direct sealing at the throttle body connection. The rubber coated steel material helps maintain a stable seal under engine heat and vibration, while the precise dimensions support proper alignment on the intake side. This gasket is a practical choice for service work on the Nissan Pathfinder and INFINITI QX4 when the original throttle body seal is worn, compressed, or leaking. Fel-Pro 61343 also cross-references MAHLE G31881 for the same application.

What It Helps Address

• Air leaks at the throttle body mounting surface
• Rough idle caused by a compromised throttle body seal
• Vacuum leak symptoms related to intake sealing loss
• Throttle body service where the original gasket no longer seals properly
• Reassembly after intake or throttle body maintenance on Nissan Pathfinder and INFINITI QX4 models

Installation Notes and Tips

Clean both mating surfaces before installation and remove any old gasket material, carbon buildup, or oil residue. Verify the throttle body and intake flange are flat and free of damage before installing Fel-Pro 61343. Use the gasket only on the listed 2001-2002 Nissan Pathfinder and 2001-2002 INFINITI QX4 applications, and confirm bolt-hole alignment and throttle body opening dimensions before final assembly.

Quality Assurance

Fel-Pro gaskets are built around application-specific sealing materials and vehicle-focused fitment to support dependable sealing performance in professional repair environments. Fel-Pro 61343 is made for the listed applications and follows the brand’s sealing-system approach for consistent service results.
