Prime Guard Synthetic Engine Oil Filter POS6128 F-250 F-350 450 SUPER DUTY 6.7L

Prime Guard® Synthetic Oil Filters deliver premium engine protection with extended service life up to 10,000 miles. Built with fully synthetic media, these step‑up filters offer 99% filtration efficiency at 30 microns for superior contaminant control.

A silicone anti‑drainback valve prevents dry starts by retaining oil during shutdown—outperforming standard NBR valves—while a durable NBR gasket ensures a strong, leak‑free seal.

Engineered with 300+ PSI burst strength, these filters are ready for demanding driving conditions. Designed to USCAR‑36 specifications, Prime Guard synthetic filters provide reliable fit and performance across applications.

They’re compatible with all oil types, including synthetic, conventional, and high‑mileage formulas, and do not affect new‑car warranties.
