6.6 Duramax (5 Micron) vs PF2232 Upgrade: Tested for Hidden Duramax Benefits
We recently pitted the 6.6 Duramax Oil Filter (5 Micron) against its predecessor, the PF2232, to uncover what makes this upgrade a standout for our hardworking 2001-2019 Chevy Silverado/GMC Sierra 2500 HD 3500 HD engines. The 5-micron filter, with its tighter filtration, delivered noticeably cleaner oil flow, reducing debris buildup and enhancing engine longevity. While the PF2232 served us well for years, the new model's superior design and compatibility with our heavy-duty trucks made a tangible difference in performance and peace of mind. Our testing revealed smoother operation, fewer clogs, and a more reliable fit-key wins for anyone prioritizing efficiency and durability. The upgrade's seamless replacement of part #114000555 also simplifies the process, ensuring no compatibility headaches. Whether you're towing or cruising, this filter proved to be a quiet, dependable partner. Though we didn't expect a dramatic shift, the results were impressive, making us rethink the value of investing in improved components for our engines.
