K&N Engine Air Filter KNA-3174 — Long-Life 18,000-Mile Replacement, High-Flow Filtration

The K&N Engine Air Filter KNA-3174 is a long-life replacement filter engineered to provide up to 18,000 miles of reliable air filtration and simple bolt-in installation for compatible vehicles.

Built on K&N’s decades of high-flow filtration experience, the KNA-3174 offers an extended service interval compared with many disposable filters while meeting or exceeding OEM fit and performance expectations. Available with premium synthetic or cellulose-blend media depending on application, this filter balances durability, protection and airflow for everyday driving. It installs quickly into the factory air box and is designed as a straightforward, no-fuss replacement part for the listed models.

How much longer will this filter last compared to a standard disposable filter?

The KNA-3174 is rated for up to 18,000 miles of service, which is roughly 50% longer than many common 12,000-mile disposable filters. That extended interval reduces replacement frequency and maintenance time for typical highway-oriented driving.

• 18,000-mile recommended replacement interval under normal highway driving.
• About 1.5 years of service at 12,000 miles driven per year.
• Fewer replacements than standard 12,000-mile filters, lowering waste and cost over time.

What kind of filtration and protection does this filter provide?

K&N uses either premium synthetic or a cellulose-blend filter media for this application, engineered to capture airborne contaminants while maintaining effective airflow. The media is rated to deliver up to 99% engine protection against common particulates, helping preserve engine components when changed at recommended intervals.

• Premium media chosen per application for optimized balance of flow and filtration.
• Up to 99% filtration efficiency against typical particles that reach the intake.
• Rugged construction resists collapse and deformation under normal operating conditions.

Will this filter fit my vehicle and how easy is installation?

The KNA-3174 is designed to meet or exceed OEM specifications and drops into the factory air box for compatible vehicles with minimal effort. Most installations require no tools and can be completed in minutes by following basic vehicle instructions.

• Direct replacement for compatible factory air box — check vehicle fit list before purchase.
• Tool-free, quick swap in many applications; follow vehicle-specific guidance where needed.
• Meets or exceeds OEM fit and sealing requirements to maintain intake integrity.

How durable is the construction and what maintenance should I expect?

K&N Advantage filters are assembled from durable materials to maintain shape and performance through their rated life. Regular inspection is advised; replace at the 18,000-mile interval under normal highway use or sooner in dusty conditions.

• Sturdy frame and pleated media resist wear over the service interval.
• Replace every 18,000 miles under typical highway driving; more frequent checks in dusty environments.
• Dispose and install a new filter at interval—these are designed as long-life replacements, not serviceable elements.

Who is this for: The K&N KNA-3174 is aimed at drivers of the compatible Mitsubishi, Nissan and Renault models who want a dependable, longer-lasting factory-fit air filter. It suits people who prefer reduced maintenance intervals, reliable engine protection, and an easy, direct-fit replacement that aligns with OEM form and function. Choose this filter if you want an extended-life, well-built replacement that installs quickly and keeps intake airflow and filtration performance consistent for up to 18,000 miles.
