DESCRIPTION

Product Overview

• This comprehensive 4-filter master maintenance kit provides a complete filtration overhaul for late-model 2020–2026 6.6L Duramax trucks. By pairing the high-flow engine air filter, cartridge-style fuel filter, upgraded heavy-duty oil filter, and high-efficiency cabin air filter into a single bundle, this kit allows you to refresh every primary filtration point on your truck in one easy garage session.
  
• Engineered to meet the elevated performance demands, higher oil pressures, and precise tolerances of modern diesel engines, this kit provides complete bumper-to-bumper protection. It shields sensitive high-pressure fuel injectors from moisture and fine particulates, prevents engine wear from soot buildup, optimizes intake airflow, and purges pollen and road dust from the passenger cabin. It is the ultimate all-in-one solution for owners who demand peak performance and zero compromise in vehicle maintenance.

Key Features

• Premium engine air filter with advanced dust-capturing media protects internal components against abrasive fine silica dust and heavy road debris.
  
• Heavy-duty synthetic-blend oil filter media delivers superior contaminant holding power and maintains stable oil pressure under high-load towing and harsh conditions.
  
• Precision cartridge-style fuel filter utilizes multi-layer coalescing media to strip water and microscopic impurities, protecting sensitive high-pressure fuel injectors.
  
• Advanced electrostatic cabin air filter actively traps diesel soot, seasonal pollen, and road dust to ensure clean interior air without restricting A/C airflow velocity.

Replacement Interval

• Target the 15,000–20,000 mile mark for fuel and engine air filter replacements (10,000–15,000 miles for severe service), replace the cabin filter every 12,000–15,000 miles (or annually), and swap the oil filter during routine oil changes (7,500 miles normal / 5,000 miles severe). Keeping cabin and intake air filters fresh preserves HVAC blower system efficiency and ensures peak engine combustion.
  

FAQ

Q: Which filter combo should I select for standard servicing?

A: Select Fuel + Oil for basic 7,500–10,000 mile engine maintenance, or choose the 4-in-1 Full Bundle to refresh engine airflow, cabin air, oil filtration, and fuel purity all in one order.

Q: What are the recommended replacement intervals for 6.6L Duramax filters?

A: Replace the Oil Filter every 5,000–7,500 miles, Fuel Filter every 10,000–15,000 miles (or when the DIC monitor reaches 0%), and both Air and Cabin Filters every 22,500 miles.

Q: Is installation simple for DIY maintenance?

A: Yes—the oil filter is a simple spin-on type, the fuel filter replaces easily from under the vehicle, and the engine air and cabin filters install in minutes with basic tools.

Q: Does this kit fit 2017–2019 Duramax 6.6L L5P models?

A: No, 2020+ Silverado/Sierra HD trucks use updated airbox and filter housing dimensions. 2017–2019 L5P models require our 2017–2019 specific filter kit.
