Detailed Description

The ECOGARD X5335 is engineered as a conventional-media engine oil filter for commercial and medium-duty use. Its spin-on construction, cellulose media, anti-drain back valve, and bypass relief valve make it suitable for engines that require stable filtration and reliable oil circulation during service intervals.

What It Helps Address

• Oil contamination from normal engine wear and suspended debris.
• Oil drain-back after shutdown that can delay pressure recovery.
• Restricted flow conditions that call for bypass valve operation.
• Routine filter service on commercial and heavy-duty engines.
• Replacement needs for vehicles using a spin-on, conventional-media filter.

Installation Notes and Tips

Verify the thread size, filter height, and outer diameter before installation. Confirm the application against the vehicle catalog, especially for Ram 2500, Ram 3500, and other heavy-duty fitments where notes specify conventional media or OEM replacement. The X5335 is a direct service part for listed applications, and the part number should be matched to the engine oil filter specification before installation.
