Purolator PBL14612 PurolatorBOSS Maximum Engine Protection

PurolatorBOSS PBL14612 is a high-performance spin-on oil filter engineered to deliver durable engine protection and dependable oil flow for select Nissan, Mazda, Infiniti and other vehicles.

This PurolatorBOSS model combines a full-synthetic filter media, reinforced backing and a heavy-duty steel casing to trap contaminants and maintain oil circulation under tough driving conditions. Built to perform with conventional and full-synthetic oils, PBL14612 aims to extend service intervals while resisting collapse, leaks and dry-start wear. It’s offered for a wide range of late-model and older vehicles — verify fitment for your exact year and engine before purchase.

How does this filter protect my engine during long oil-change intervals?

The PBL14612 uses SmartFUSION full-synthetic media bonded to a polymer mesh to capture tiny particles and hold dirt without restricting flow. Purolator rates this design to support extended mileage intervals and to maintain filtration efficiency as the element loads.

• Full synthetic filter media for consistent dirt capture
• Reinforced backing prevents media collapse under pressure
• Silicone anti-drainback valve reduces dry starts on engine restart
• Designed to support long service intervals recommended by vehicle manufacturers

What features improve durability and oil flow in extreme conditions?

PBL14612 combines a robust BOSS steel shell with an innovative double-helix center tube to resist deformation and maintain oil throughput. The construction is intended for frequent towing, extended idling, stop-and-go city driving and high-temperature environments.

• Heavy duty steel casing for structural strength and impact resistance
• Double-helix, high-flow center tube offers enhanced strength over side-seam tubes
• Ethylene acrylic PuroSEAL gasket for reliable sealing and leak protection
• Engineered to withstand higher pressures and thermal cycles

Will this filter work with synthetic oils and modern engines?

Yes — SmartFUSION media and the filter’s internal architecture are compatible with conventional and full-synthetic oils and a broad range of viscosities. The design focuses on maintaining filtration performance and oil delivery across engine types and oil formulations.

• Optimized for full-synthetic and conventional oil use
• Anti-drainback valve protects lubrication at startup
• Suitable for vehicles where manufacturers approve extended-oil-change intervals
• Compatible with many Nissan, Mazda, Infiniti and other makes (confirm exact fit)

How do I confirm fitment for my car?

Fitment is specific to model year and engine; always check compatibility tools or your vehicle’s parts guide before ordering. The PBL14612 is offered for many models across Nissan, Mazda, Infiniti and other manufacturers, but exact fitment must be verified.

• Reference your vehicle’s year, make and engine code
• Use online fitment tools (for example, retailer-confirmed fit guides)
• Compare thread size and gasket dimensions if unsure
• Contact a professional if you need installation confirmation

Who is this for? PurolatorBOSS PBL14612 is aimed at drivers who want rugged, high-efficiency filtration for extended service intervals and challenging driving — owners of compatible Nissan, Mazda and Infiniti vehicles, fleet operators, tow vehicles and anyone who prefers full-synthetic oil performance. If you prioritize high dirt-holding capacity, reliable sealing and robust internal construction for heavy use, this filter is a strong candidate. Verify exact vehicle fitment before purchase to ensure correct application.
