BDFHYK Engine Air Filter CA7440 for Nissan Frontier & Armada - Direct-Fit, Microporous Media

If you drive a Nissan Frontier, Armada, Titan, Pathfinder, Xterra, select NV vans, an Infiniti QX56, Jeep Grand Cherokee, or Suzuki Equator, the BDFHYK CA7440 is built to match the factory airbox dimensions and filtration performance. Constructed with microporous filter media, this cartridge filters out airborne particles that would otherwise enter the intake system. It’s designed for easy, tool-free installation and replaces a long list of OEM and aftermarket part numbers so you can swap it in with confidence.

How does this filter protect my engine during daily driving?

The CA7440 captures dust, pollen, soot, and other particulates before they can reach the throttle body and combustion chambers. By keeping abrasive debris out of the engine, the filter helps maintain steady airflow and can reduce premature wear on moving parts. It’s not a performance part; it’s a preventive maintenance item that helps the engine operate as intended.

• Microporous media traps fine and coarse contaminants.
• Seals to the factory airbox to prevent bypass.
• Designed to maintain correct airflow for stock engines.

Will the BDFHYK CA7440 fit my vehicle model and year?

This cartridge is made to replace part numbers such as CA7440, AF7845, A1267C and several OEM references, and it fits many Nissan, Infiniti, Jeep, and Suzuki models across multiple years. Fitment varies by year and engine option, so verify your application with your vehicle’s year, make and model before purchase. The product matches factory dimensions so installation uses the existing airbox without modifications.

• Compatible with Nissan Frontier (2005–2024) and Armada (2005–2015).
• Fits NV1500/2500/3500 (2012–2021), Pathfinder (2005–2012), Titan (2004–2015).

How often should I replace this air filter, and how simple is installation?

Recommended replacement intervals are typically every 12 months or 12,000 miles, or according to your vehicle manufacturer’s guidelines. Replacement is straightforward: the CA7440 is built to the same shape as the OEM filter so it drops into the factory airbox without trimming or special tools. After replacing the filter, check the airbox seal and fasteners to ensure a tight fit.

• Suggested change interval: ~12 months / 12,000 miles.
• Direct-fit design—no cutting, glue, or adapters required.
• Quick visual inspect of the airbox recommended after installation.

What part numbers and cross-references does this replace?

The BDFHYK CA7440 cross-references a number of OEM and aftermarket part numbers so it’s easy to match when shopping. Using the compatible references reduces the chance of ordering the wrong cartridge for your vehicle. Always confirm compatibility with your vehicle’s specific year and engine to avoid mismatches.
