MITZONE Valve Cover Kit for Nissan Altima & Sentra 2.5L (2002–2006) — Complete Gasket & Spark Plug Tube Seals

MITZONE's complete engine valve cover kit replaces the worn valve cover assembly, gasket, spark plug tube seals, oil filler cap and mounting hardware for 2002–2006 Nissan Altima and 2002–2006 Sentra 2.5L models.

This replacement assembly is a one-piece valve cover pre-fitted with a durable cover gasket, four spark plug tube seals, hardware and an oil filler cap so you can restore a sealed, factory-style top end without sourcing multiple parts. The kit is manufactured to meet OEM fit standards, uses resilient materials to resist oil and heat exposure, and includes the common OE reference numbers (13264-3Z001 / 264-982) for easy cross-checking with your vehicle.

Will this valve cover kit fit my Nissan Altima or Sentra?

The kit is built specifically for 2.5L QR25DE engines found in many Nissan models from the early 2000s. It lists compatibility with model trims and years where this engine was used, but always verify against your vehicle's engine code and part number before ordering.

• Compatible with 2002–2006 Altima (Base, S, SL where equipped with 2.5L)
• Compatible with 2002–2006 Sentra variants including SE-R, SE-R Spec V, Limited Edition and 2004 Sentra S
• OE references: 132643Z001, 13264 3Z001, 13264-3Z001, 264-982 for cross-checking
• If in doubt, match the existing cover’s shape and bolt pattern to confirm fitment

What parts are included and how does that simplify the repair?

This kit arrives as a ready-to-install valve cover assembly with the primary sealing components pre-installed, reducing time hunting for matching gaskets and seals. The included hardware and oil filler cap let you replace the entire top cover assembly in one visit, minimizing leak troubleshooting later.

• One pre-assembled valve cover with integrated gasket
• Four spark plug tube seals and mounting bolts included
• Oil filler cap and breather tube supplied for a complete top-end refresh
• Ships ready to fit—no need to press or glue additional seals

How durable and leak-resistant is this replacement compared to OEM?

The components are molded from materials chosen to withstand oil, heat cycles and vibration common to valve covers, and the gasket is formed for a continuous seal to reduce leak points. While it’s not an original OEM brand, the assembly follows the same sealing principles and OE reference numbers to offer reliable service life when installed correctly.

• Continuous, seamless gasket design to limit oil seepage
• Spark plug tube seals sized to prevent oil ingress around plugs
• Durable plastic cover and oil cap rated for engine bay conditions
• Includes bolts to ensure correct torque and clamp pattern

Who is this best for? This MITZONE valve cover kit is aimed at DIY mechanics, independent shops and vehicle owners who want a complete, budget-conscious replacement for a leaking or damaged valve cover on 2.5L Nissan engines from 2002–2006. It’s ideal when you prefer one part number to replace the cover plus seals and cap together, cutting install time and follow-up troubleshooting. If you are unsure about fitment, compare your current part number or consult a technician before purchase.
