Doc's Diesel 6.6L Duramax Filter Set for Chevrolet/GMC 2001-2016 — DPS9059 Fuel & D5399 Oil, Replaces TP3012

If you own a 6.6L Duramax-powered Chevrolet or GMC truck from model years 2001–2016, this matched filter set supplies the fuel and oil filtration components needed for a single scheduled service. Each filter is selected to meet or exceed original-equipment filtration specs and arrives as a paired solution so you change both systems without hunting for separate parts.

How does this filter set protect my Duramax engine?

These two filters act on different contamination sources: the DPS9059 fuel filter removes microscopic particulates and water from diesel before it reaches injectors, while the D5399 oil filter captures metal and debris circulating in engine oil. Together they reduce wear on high-pressure components and help keep fuel and oil systems operating within their design tolerances.

• DPS9059 fuel filter tested 96.92% efficient down to 3 microns.
• D5399 oil filter tested 99% efficient down to 25 microns.
• Designed to match flow and capacity requirements for 6.6L Duramax applications.

Will these filters fit my specific truck model and year?

This set is built for the 6.6L Chevrolet and GMC Duramax engines from 2001 through 2016 and is intended to replace TP3012-equivalent parts. Use the fitment card on the product page to confirm compatibility with your truck’s year and configuration before ordering to ensure a correct match.

• Designed and tested for 2001–2016 6.6L Duramax models.
• Replaces TP3012-style fuel filter applications.
• Fitment verification recommended via the page fitment tool.

What maintenance schedule should I follow with these filters?

Service intervals depend on driving conditions and your vehicle’s warranty guidelines. Generally, change fuel filters every 5,000–10,000 miles under typical use, up to 15,000 miles maximum, and follow manufacturer-recommended intervals for oil changes that suit your mileage and operating conditions.

• Fuel filter: 5,000–10,000 miles typical, 15,000 miles maximum.
• Oil filter: change at each oil service per vehicle manufacturer guidance.
• Adjust intervals for heavy towing, dusty conditions, or poor fuel quality.

What comes in the box and why buy the matched set?

This single purchase contains the DPS9059 fuel filter and D5399 oil filter sized for the same Duramax application so you can service both systems in one visit. Matching components simplifies maintenance, reduces parts-compatibility guesswork, and ensures filtration performance across fuel and oil systems is balanced for this engine family.

• Includes: one DPS9059 fuel filter and one D5399 oil filter.
• Each piece selected and tested for the 6.6L Duramax application.
• Saves time versus sourcing separate compatible filters.

Who is this for: This Doc's Diesel filter set is geared toward Chevrolet and GMC Duramax owners, fleet managers, and independent technicians who want a reliable, matched fuel-and-oil filtration pair for 2001–2016 6.6L engines. If you perform scheduled maintenance, tow regularly, or operate in challenging environments where fuel and oil cleanliness matters, this paired set streamlines servicing and restores filtration to factory-level expectations.
