BDFHYK Engine Air Filter CA7440 — Direct-Fit for Nissan Frontier & Armada, Microporous Pleated OEM Fit

The BDFHYK CA7440 is a direct-fit replacement engine air filter engineered to trap dust and debris for Nissan, Infiniti and compatible Jeep/Suzuki models.

Whether you maintain an older pickup or a rugged SUV, the CA7440 is built to match factory dimensions and filtration performance without modification. This replacement filter fits a wide range of Nissan models (Frontier, Armada, Titan, Xterra, Pathfinder), select Infiniti QX56 years, NV commercial vans, and compatible Jeep Grand Cherokee and Suzuki Equator models. It uses a fine, microporous media to capture airborne particles that can reduce engine efficiency and accelerate wear.

How does this filter protect my engine during everyday driving?

The CA7440’s pleated filter media increases surface area for particle capture while maintaining airflow. By filtering out grit, pollen, soot and other contaminants, it helps keep intake components cleaner and supports consistent combustion.

• Microporous pleated media traps fine particles without excessive airflow restriction
• Deep-filter construction extends service life compared with thin paper elements
• Factory-matching shape ensures a tight seal in the air box to prevent bypass

Which vehicles and part numbers is this compatible with?

The CA7440 replaces multiple OEM and aftermarket part numbers and fits many model years across Nissan, Infiniti, Jeep and Suzuki lineups. Always verify fitment with your vehicle year and model before purchase.

• Replaces: CA7440, AF7845, A1267C, A44727, 6213 and related numbers
• Fits: Nissan Frontier (2005–2024), Armada (2005–2015), Titan (2004–2015), Xterra (2005–2015)

How easy is it to install and when should I replace it?

Installation matches the original factory design, so the CA7440 drops into the existing air box without cutting or special tools. Replacement frequency depends on driving conditions, but following routine intervals keeps engine breathing clean.

• Direct-fit design for tool-free swap into the factory air box
• Recommended replacement: about every 12 months or 12,000 miles, or per your vehicle manufacturer
• Check more often when driving in dusty or off-road environments

What performance trade-offs should I expect?

This filter balances filtration efficiency with unrestricted airflow to maintain factory engine performance and fuel economy. It’s designed for original-equipment airflow characteristics rather than high-flow aftermarket tuning filters.

• Designed for OEM airflow to preserve engine calibration and emissions behavior
• Offers improved particle capture compared to worn or damaged stock elements
• Not a specialized performance intake filter for modified engines

Who is this for? The BDFHYK CA7440 is suited to owners of compatible Nissan and Infiniti vehicles, fleet operators running NV series vans, and drivers of older Jeep or Suzuki models seeking a reliable, low-cost replacement. If you want a direct-fit air filter that installs easily, restores clean intake air, and matches many original part numbers, this filter is a practical maintenance choice. Always confirm fitment with your specific year and model prior to purchase to avoid mismatches.
