K&N Engine Air Filter KNA-2395 18,000-Mile Replacement — Direct-Fit, High-Efficiency

K&N KNA-2395 is a long-life engine air filter engineered to replace your factory element and deliver up to 18,000 miles of dependable filtration without sacrificing airflow.

Designed by K&N — the performance air filtration brand trusted since 1969 — this Advantage Plus filter uses a premium synthetic or cellulose-blend media (application dependent) to combine extended service life with high-efficiency particle capture. It installs directly into the factory air box for a quick swap and is built to meet or exceed OEM specifications for fit and function in compatible Ford, Lincoln, Mazda and Mercury models listed in the product description.

How does this filter balance long life and engine protection?

The KNA-2395 is formulated to extend replacement intervals while maintaining strong filtration efficiency. K&N’s media is rated to capture a high percentage of engine-damaging particles while offering increased contaminant-holding capacity so the filter can go longer between changes.

• Rated for up to 18,000 miles under normal highway driving conditions.
• Premium synthetic or cellulose-blend media for robust particle capture.
• Up to 99% efficiency in stopping harmful debris, depending on application.
• Designed to meet or exceed OEM sealing and dimensional requirements.

Will it fit my vehicle and how easy is installation?

This K&N replacement is produced to match factory footprint and mounting details, so it fits directly into the original air box of listed Ford, Lincoln, Mazda and Mercury models without modification. Installation is a simple, tool-minimal process that most owners can complete in minutes.

• Direct-fit for select 2007–2026 models (see product compatibility list).
• Installs into the factory air box — no trimming or adapters required.
• Typical installation time: only a few minutes for most vehicles.
• OEM-style sealing prevents air bypass when installed correctly.

What performance or maintenance differences should I expect?

Compared with conventional disposable filters designed for shorter intervals, this 18,000-mile K&N element reduces how often you replace your air filter while keeping airflow and filtration balanced. Regular inspection is still recommended: check the filter during routine maintenance and replace it at the suggested interval or sooner in dusty conditions.

• 50% longer recommended service interval versus typical 12,000-mile filters.
• Maintains proper airflow characteristics for engine performance consistency.
• Check more frequently if you drive in heavy dust, off-road, or construction areas.
• Backed by a 1-year limited warranty for manufacturer coverage.

How does K&N’s manufacturing quality affect reliability?

K&N builds Advantage Plus filters with rugged materials and attention to sealing, dimensional accuracy and media consistency so the replacement behaves predictably in everyday driving. The construction is tuned to resist degradation over the filter’s service life while providing stable filtration and fit.

• Durable construction tailored for up to 18,000 miles of service life.
• Media and seal engineering to resist collapse or bypass under normal conditions.
• Manufactured to meet K&N quality standards and OEM fitment expectations.
• Supported by K&N’s longstanding expertise in performance air filtration.

Who is this for? The K&N KNA-2395 is aimed at owners of compatible Ford, Lincoln, Mazda and Mercury vehicles who want a direct-fit replacement that reduces replacement frequency without compromising filtration performance. It’s a practical choice for drivers who perform routine vehicle maintenance, value long-life aftermarket parts, and prefer an easy, factory-compatible swap to the stock air filter. If you regularly drive in very dusty or harsh environments, inspect and replace the element more often than the nominal 18,000-mile interval.
