iFJF Fuel Filter 5-Micron Replacement for Duramax 6.6L — 2-Pack Twist-On, OEM Fit

The iFJF TP1015 is a 5-micron replacement fuel filter designed to protect Duramax 6.6L engines by trapping water, dirt, and microscopic contaminants.

Built as a direct-fit replacement for OEM part numbers and supplied as a two-pack, the TP1015 gives you a multi-layer filtration element in a twist-on housing for fast, tool-free service. It’s engineered to match factory dimensions and flow characteristics for Chevy and GMC diesel models equipped with the 6.6L Duramax or Cadillac L5P engines from select model years. Use it to restore clean fuel delivery, help reduce injector wear, and maintain consistent engine performance between service intervals.

Which vehicles is this filter compatible with?

The TP1015 fits many GM diesel platforms that use the superseded OEM numbers 22937279, 23456595, and 23304096. Compatibility covers recent 6.6L Duramax trucks and certain Cadillac 3.0L L5P applications—check your vehicle’s part number to confirm fit.

• Chevy Silverado/GMC Sierra 2500HD, 3500HD (2017–2024)
• Medium-duty models 4500HD, 5500HD, 6500HD (2021–2024)
• Cadillac 3.0L L5P Duramax models (2021–2024)
• Replaces OEM numbers: 22937279, 23456595, superseded by 23304096

How does the 5-micron rating help my engine?

A 5-micron pleated element captures fine particulate and helps separate water from diesel before it reaches injectors and high-pressure fuel systems. That finer level of filtration reduces abrasive wear and keeps fuel delivery components operating more reliably over time.

• Micron rating targets microscopic particulates that cause injector damage
• Multi-layer media improves dirt-holding capacity and water shedding
• Cleaner fuel flow supports stable combustion and consistent performance

Is installation difficult and what’s included in the kit?

Installation is straightforward: the TP1015 uses a twist-on cartridge design that lets you replace the filter element quickly without specialized tools. The kit contains two complete TP1015 fuel filters so you have a spare for your next service.

• Twist-on cartridge for quick hand-install or using a standard strap wrench
• Drop-in replacement built to match OEM dimensions and sealing surfaces
• Package includes 2 x TP1015 fuel filters for back-to-back services

What performance and reliability features should I expect?

The TP1015 combines multi-layer filter paper with engineered end-caps to maintain flow while intercepting contaminants and free water. Manufactured to meet fit, form, and function expectations, it helps maintain fuel-system cleanliness without changing factory service intervals.

• Advanced multi-layer media for efficient contaminant capture
• Water separation properties reduce moisture reaching injectors
• Engineered shell and internals to preserve OEM flow rates

Who is this for? The iFJF TP1015 is aimed at owners and fleet managers of GM Duramax diesel trucks and compatible Cadillac L5P vehicles who want a cost-effective, OEM-form replacement filter that restores clean fuel delivery. It’s ideal for DIY mechanics who prefer fast, twist-on service and for technicians seeking a dependable two-pack to keep trucks on the road with minimal downtime. Always cross-check your vehicle’s OEM part number to ensure proper fit before purchase.
