• Fits 2007–2014 Nissan Maxima (3.5L V6 CVT versions).
• Fits 2007–2013 Nissan Altima, 2009–2014 Murano, 2011–2017 Quest with the same CVT setup.
• Designed for OEM-style mounting and seal interfaces to simplify installation.

What materials and construction features improve durability?

This assembly uses corrosion-resistant stainless steel and precision manufacturing methods to withstand the thermal and mechanical stresses inside a CVT oil cooler. The robust construction helps resist wear from debris and repeated thermal cycles common in transmission service life.

• Stainless steel body resists corrosion and maintains structural integrity.
• Precision-formed filter elements for consistent contaminant capture.
• Durable sealing surfaces and fastener points to prevent leaks.
• Manufactured to endure harsh operating environments typical under the hood.

How does replacing the oil filter assembly affect transmission performance?

Replacing a worn or clogged filter assembly helps maintain proper fluid flow and heat transfer within the CVT oil cooler, supporting smoother operation and reducing strain on internal components. While not a guaranteed fix for all transmission issues, a fresh filter assembly is a standard service step to preserve fluid cleanliness and cooling efficiency.

• Improves dirt and particle removal from transmission fluid.
• Supports stable fluid temperature regulation via the oil cooler.
• Helps maintain hydraulic performance of the CVT system.
• Recommended during scheduled transmission service or when replacing the cooler.

What warranty and service assurances come with the part?

KAIZHINAN provides a one-year warranty covering manufacturing defects, offering buyers a period of protection after purchase. The warranty supports confidence in the product’s fit and expected operational durability under normal use.

• One-year limited warranty against manufacturing defects.
• Product tested for consistent fit with specified Nissan models.
• Sold as a replacement assembly to match OEM part references for easier sourcing.

Who is this for: This KAIZHINAN CVT Oil Cooler Filter Assy is intended for DIY mechanics, professional technicians, and Nissan owners who need a cost-effective, OEM-compatible replacement for the 31726-1XE0A oil filter assembly.
