aFe 44-LF004 Pro Guard D2 Spin-On Oil Filter for 7.3L Powerstroke Diesel

The aFe Power 44-LF004 Pro Guard D2 is a high-performance spin-on oil filter engineered specifically for the demands of heavy-duty diesel engines. Built as a direct OE replacement, it utilizes the factory canister for a secure, leak-free fit and trouble-free installation.

Diesel engines operate in some of the most demanding filtration environments outside of motorsport. High compression ratios, tight internal tolerances, and turbocharging all place extreme stress on engine oil and the filter protecting it. The Pro Guard D2 rises to that challenge with its NF21 full-synthetic filter media, which delivers outstanding filtration efficiency without sacrificing the high oil flow rates that turbocharged diesel engines require. The filter is tested and validated to ISO 4548-12 standards.

Key Features:

• NF21 Full-Synthetic Filter Media — Maximum filtration with minimal flow restriction
• High-Strength Steel Canister — Heavy-duty construction for long service life
• Built-In 3/8" Ratchet Drive Boss with 1" Square Boss — Makes filter removal fast and easy with a standard socket or ratchet
• Built-In Seal — Ensures a leak-free installation every time
• Direct OE Replacement — Drops into the factory canister location with no modifications
• Tested to ISO 4548-12 — Meets rigorous international filtration efficiency standards
