Buying Guide

Match fitment to your vehicle

Confirm engine size and model years (for example 3.6L Jeep/Dodge fitments) or universal vs vehicle-specific designs to avoid adaptation work

Prefer aluminum housings

Aluminum oil-filter housings and integrated oil coolers offer better heat transfer and corrosion resistance versus basic stamped steel units

Check included gaskets and sensors

Kits that include gaskets and sensor ports reduce parts sourcing and ensure a proper seal for oil and coolant passages

Consider transmission cooler dimensions

For transmission-style coolers, compare core size (e.g., 9.5 x 11 type panels) and mounting options to ensure adequate cooling capacity and fit in your vehicle

Review user ratings and value scores

Prioritize products with strong user ratings (4.5 stars and up) and positive value assessments to balance cost against durability and performance
