Detailed Application Coverage

Standard Ignition PG87 is used in intake manifold and plenum sealing service on Nissan Altima, Nissan Maxima, Nissan Murano, and Nissan Quest models. It is a direct-fit sealing component for lower intake service on 2004-2009 Nissan Quest and 2003-2007 Nissan Murano, and it also covers 2002-2008 Nissan Maxima and 2002-2006 Nissan Altima applications. This part cross-references Walker Exhaust 50091 for the same application.

What This Gasket Helps Address

• Intake air leaks at the plenum-to-manifold sealing surface
• Vacuum leaks that can affect idle quality and drivability
• Loss of sealing integrity during intake manifold service
• Replacement needs after intake system disassembly
• Fitment-specific sealing for Nissan Altima, Maxima, Murano, and Quest

Installation Notes and Tips

Verify the intake manifold and plenum surfaces are clean, flat, and free of old gasket material before installation. Match the gasket to the lower intake position where specified, and confirm the 6-port layout and 3-bolt-hole pattern before assembly. Standard Ignition PG87 should be installed during intake service to restore proper sealing on the listed Nissan applications.
