Fel-Pro MS95899 is a fuel injection plenum gasket for Toyota 3.4L V6 5VZ-FE engines, built to help restore a tight upper plenum seal when vacuum leaks cause rough idle, lean-condition codes, poor drivability, or misfires. The fiber-based construction and stamped silicone seal ring give the repair a forgiving sealing surface for real-world intake service, making it a practical replacement for aging or leaking upper plenum gaskets on 4Runner, T100, Tacoma, and Tundra applications.

Fel-Pro MS95899 Features:

• Fiber-based gasket material is designed to conform to imperfect sealing surfaces commonly found during aftermarket intake repairs.
• Stamped silicone seal ring supports a positive seal at the upper fuel injection plenum, helping control unmetered air leaks that can affect idle quality and air-fuel mixture.
• Application-specific engineering targets Toyota 3.4L V6 5VZ-FE intake plenum service rather than a universal cut-to-fit repair.
• Designed as a cost-conscious alternative to rigid metal OEM-style gaskets while retaining the flexibility needed for dependable sealing.
• Useful when servicing upper plenum vacuum leaks linked to rough idle, lean diagnostic trouble codes, reduced fuel economy, or unexpected misfires.

Fits Toyota 4Runner 1996-2002, T100 1995-1998, Tacoma 1995-2004, and Tundra 2000-2004 models equipped with the 3.4L V6 5VZ-FE engine. Verify engine code and plenum service location before ordering.
