Performance Air Filter for Maserati Grancabrio/Granturismo/Quattroporte with 4.2L 4.7L Engines

Your Maserati’s F136 V8 is one of the greatest sounding engines ever produced—a naturally aspirated Italian masterpiece that demands to breathe. Don't stifle that throttle response with a disposable paper filter designed for economy cars. It's time to upgrade to the filtration standard used by the factory’s own racing teams.

Performance Replacement Air Filter for Maserati GranTurismo, GranCabrio & Quattroporte (F136 V8)

The Maserati M139 and M145 platforms are defined by their engines. Whether you have the 4.2L or the torque-rich 4.7L, you are driving a vehicle powered by the legendary F136 V8 family, co-developed with Ferrari. From the factory, however, these engines draw air through dense paper filters. While adequate for basic filtration, paper filters rely on surface area to trap dirt, which quickly creates a restriction in airflow as contaminants build up. On a high-revving engine that drinks massive amounts of air at 7,000 RPM, this restriction translates to lost throttle sharpness.

This BMC replacement filter (FB546/20) is the exact solution for owners who want motorsport-grade performance without modifying the stock airbox. Unlike paper, BMC filters utilize a multi-layered cotton gauze soaked in low-viscosity oil, sandwiched between an epoxy-coated alloy mesh. This design allows for significantly higher air volume to pass through while actually improving filtration efficiency—trapping particles as small as 7 microns (compared to the OEM standard of 10 microns). This isn't just an aftermarket accessory; BMC is the Tier 1 supplier for many of the world's most prestigious supercar manufacturers.

By switching to this filter, you aren't just improving airflow; you are investing in a lifetime component. The "Full Moulding" construction eliminates welded joints that can crack over time, ensuring durability in the high-heat environment of a Maserati engine bay. Plus, rather than throwing away expensive OEM filters at every service interval, you simply wash and re-oil this unit, making it a smart financial decision for long-term ownership.

Why You Need This Upgrade

• Unrestricted Breathing: Replaces restrictive paper media with high-flow cotton gauze, allowing the V8 to inhale freely at high RPMs.
• Superior Protection: Traps impurities as small as 7 microns, ensuring that road debris never reaches your cylinder walls.
• Lifetime Durability: Features a one-piece molded red rubber chassis that resists heat and vibration, preventing seal failure.
• Maintenance Savings: Fully washable and regenerable, ending the cycle of buying disposable filters for every service.
• OEM Fitment: Drop-in design fits perfectly into the factory airbox with no modifications required.

Installation Notes

Installation is a straightforward process that can be done in your driveway. The filter drops directly into the OEM airbox location. When servicing the airbox on the GranTurismo or Quattroporte, take care not to overtighten the airbox screws, as the threaded inserts in the plastic housing can be delicate. Ensure the rubber seal is seated correctly to prevent unmetered air from entering the engine.
