Pacific Performance Engineering Premium Tall High-Efficiency Oil Filter 114000750 for 2020+ GM 6.6L Duramax L5P (Replaces PF26)

Overview

Elevate your Duramax oil filtration with the Pacific Performance Engineering Premium Tall Oil Filter 114000750, built for 2020 and newer GM 6.6L Duramax L5P engines. This oversize design replaces PF26 and is engineered to handle demanding service while remaining compatible with both synthetic and conventional oils. Note that installation on certain L5P models may require the PPE fuel pump relocation bracket 114002700 to ensure a precise fit.

Why this filter stands out

• Superior filtration: 522 square inches of 5 micron media deliver a large surface area for more efficient contaminant capture.
• Sturdy construction: A thicker base plate and a perforated metal center core provide added strength to withstand higher oil pressures.
• Protective features: A silicone anti-drain-back valve helps prevent dry starts, while a by-pass valve with a stiffer spring and rubber seal maintains reliable oil flow when needed.
• Debris control: A high-power magnet works to attract ferrous metal debris before it circulates through the engine.
• Durable materials: Built with silicone, rubber, and metal designed for long-term performance in varied operating conditions.

Design, materials, and fit

Designed specifically for the 2020 and newer GM 6.6L Duramax L5P platform, this filter is compatible with both synthetic and conventional oils. The larger media surface and reinforced components are intended to sustain oil cleanliness under heavy use, startup in cold conditions, and sustained high rpm operation. Because the filter is oversized, pairing it with the PPE fuel pump relocation bracket 114002700 ensures a proper fit on applicable L5P vehicles.

Real-world use and expectations

In daily driving and demanding towing scenarios, the expanded filtration area can help maintain strong oil flow and filtration performance between changes. The magnet and robust bypass design contribute to a more resilient oil path during high-load conditions, while the anti-drain-back valve supports quick, reliable oil pressure right after startup. If you operate in extreme climates or at high engine speeds, these design elements may work together to support cleaner oil and consistent performance without promising specific results.

What to expect in practice

• Potentially improved oil cleanliness under heavy workloads and longer service intervals.
• Stable oil flow during startup and fast throttle transitions.
• Reduced risk of bypass events due to a stronger bypass mechanism and reliable seals.
• Effective debris management thanks to the integrated magnet.
