  • Flow rate: 9-11 GPM

Detailed Product Overview

Wix recommends this filter for conventional, synthetic, and synthetic-blended motor oils, with service intervals aligned to OEM oil and filter change schedules. In normal and severe driving, including stop-and-go traffic, short trips, dirt roads, construction sites, and interstate use, the filter is engineered to trap contaminants while maintaining oil circulation. The Wix 51347 is also rated to capture more dirt than Protec in severe-duty use, and laboratory testing cites high efficiency at fine particle sizes.

This part cross-references FRAM PH2849A and NAPA Gold Filters 1347 for the same application.

What It Helps Address

  • Engine wear from contaminated motor oil
  • Oil starvation during cold starts after shutdown
  • Reduced filtration performance in severe driving conditions
  • Premature oil filter service issues from extended use
  • Inconsistent oil flow through a restricted filter element

Installation Notes and Tips

Verify thread size, gasket sealing surface, and overall filter dimensions before installation. Replace the filter at the manufacturer-recommended oil change interval, and pre-fill only if the vehicle service procedure allows it. For best results, install with clean engine oil on the gasket and tighten according to the filter and vehicle service specifications.

Quality Assurance

Wix positions this filter for OEM-recommended service intervals and severe-duty operation. The flexible silicone anti-drainback valve is used when applicable to help protect against dry starts beyond the traditional filter change interval.
