What components are included and why that matters?

Instead of selling only the covers, this kit supplies all wearable parts you'll likely replace when servicing the valve cover area. That reduces installation time and the risk of leaks from reused seals or missing fasteners.

• Front and rear valve covers — complete replacements
• Full set of bolts for secure mounting and proper torque distribution
• Valve cover gaskets and spark plug tube seals to prevent oil seepage
• Oil filler cap and PCV cover to restore sealed ventilation and access

How durable and leak-resistant are these MITZONE covers?

The covers are manufactured to withstand typical under-hood temperatures and resist warping that can cause leaks. Combined with new gaskets and tube seals, the set restores a tight seal and minimizes common oil-leak sources around the valve covers.

• Robust material selection for thermal stability
• Precision molded sealing surfaces for gasket compatibility
• Complete sealing parts included to address multiple leak points
• Designed specifically for early VQ35DE geometry to reduce fitment issues

Can I install this myself and what should I check first?

Many mechanically-inclined owners can complete the swap with basic hand tools and a torque wrench, but confirm engine type and compare part shapes with your old covers before starting. Follow manufacturer torque specs and clean mating surfaces to ensure reliable sealing.

• Verify vehicle model, year, and VQ35DE engine before purchase
• Clean surfaces and remove old gasket residue for proper seating
• Use supplied bolts and torque to factory specifications
• Inspect PCV and breather passages for blockages during service

Who is this for: This MITZONE valve cover set is aimed at DIY mechanics, independent shops, and vehicle owners replacing worn or leaking valve covers on early Nissan and Infiniti VQ35DE 3.5L engines. It’s ideal when you need a full, year-specific replacement kit that includes all mounting hardware and sealing components to complete the repair without extra parts runs.
