ATRACYPART Diesel 6.6L Duramax Filter Kit 2020–2024 Chevy/GMC Fit — Fuel, Oil & Air Set

This filter kit bundles the fuel, oil, and air elements engineered to match OE fitment for Chevy and GMC 2500HD/3500HD models from 2020 through 2024. Each cartridge is manufactured from high-grade media and sealed components, tested for consistent capture rates and durability. Installing the right filter combination helps reduce contaminants entering sensitive systems, supports steady fuel flow, and maintains engine breathing and lubrication integrity under heavy-duty conditions.

How will this kit affect my Duramax's day-to-day performance?

Replacing worn filters with properly sized, high-efficiency elements keeps contaminants out of the fuel and oil systems and preserves unrestricted airflow. That supports smoother operation, more consistent fuel delivery, and reliable lubrication, which you notice as steadier idle and throttle response.

• Fuel element traps water and solids to protect injectors and fuel pump.
• Oil filter removes metallic particles and combustion byproducts for cleaner oil.
• Air element maintains proper intake flow and helps prolong turbo life.

What specific parts does this kit replace and fit?

The set is matched to common OE numbers so you can confirm compatibility with your vehicle. It replaces TP1015 fuel filters, PF26 oil filters, and A3248C air filters, aligning with known OEM equivalents for direct fitment in 2020–2024 Duramax 6.6L trucks.

• Fuel filter references include TP1015 and multiple OE cross-numbers.
• Oil element cross-references PF26 and associated OE numbers for PF26-type housings.
• Air filter corresponds to A3248C and related OE listings like 84554703/Wa11057 variants.

How durable and reliable are the filters under heavy-duty use?

These elements are built from multilayer media and robust sealing materials to resist leaking and media collapse under pressure. They undergo quality checks to ensure consistent filtration efficiency and extended service intervals relative to lower-grade replacements.

• Multi-layer filtration tissue for sustained particle capture.
• Reinforced seals to minimize bypass and fluid leaks.
• Manufacturing checks to verify dimensional accuracy and flow characteristics.

How do I know when to change these filters and what to check during installation?

Follow your truck manufacturer’s recommended service intervals and inspect filters during routine maintenance. Replace sooner if you notice fuel system hesitation, increased soot in oil, or restricted airflow symptoms; always ensure proper torque and seal seating at installation.

• Observe scheduled intervals in your owner’s manual for fuel, oil, and air filters.
• Check for proper gasket placement and tighten to specified torque to prevent leaks.
• Dispose of used filters according to local regulations and verify new part numbers before fitting.
