K&N Engine Air Filter KNA-2364 — 18,000-Mile Long-Life Replacement for Jeep Wrangler, High-Flow

The K&N Engine Air Filter KNA-2364 is a long-life replacement air filter engineered to deliver up to 18,000 miles of reliable engine protection and improved airflow over traditional disposable filters.

K&N has led high-flow performance air filtration since 1969. The KNA-2364 applies K&N’s proven filter media in a premium long-life format intended for everyday drivers who want extended service intervals without sacrificing engine protection. Built to meet or exceed OEM fit and filtration needs, this drop-in filter fits factory air boxes on compatible Jeep Wrangler models and installs in minutes.

How does this filter differ from a standard 12,000-mile disposable filter?

The KNA-2364 is engineered for longer service intervals and uses an upgraded synthetic or cellulose-blend media depending on application, offering improved longevity while maintaining high filtration efficiency. Instead of replacing the filter more frequently, you can expect up to 18,000 miles of service under normal highway driving.

• Rated for up to 18,000 miles between replacements under normal use
• Approximately 50% longer service life versus many 12,000-mile filters
• Premium media delivers up to 99% filtration efficiency
• Durable construction resists deformation and routine handling

Will the KNA-2364 fit my Jeep Wrangler and how easy is installation?

This K&N replacement is designed to match OEM dimensions for listed Jeep Wrangler model years so it drops into the factory air box without modification. Most installs require no special tools and take only a few minutes, making it a straightforward maintenance task.

• Compatible with multiple Jeep Wrangler model years (see product fitment)
• No cutting or custom fitting—replaces stock filter directly
• Typical installation completes in minutes with common hand tools or none
• Instructions provided or available from K&N if needed

What kind of protection and performance can I expect?

K&N designs this filter to balance airflow and filtration so your engine breathes effectively while being shielded from particulates. The synthetic or cellulose-blend media traps contaminants with high efficiency while the robust frame holds shape under normal service conditions.

• Up to 99% engine protection from airborne contaminants
• High-flow media supports efficient intake airflow
• Sturdy frame and seal maintain consistent fit and performance
• Meets or exceeds common OEM filtration specifications

How often should I check or replace this long-life air filter?

Under ordinary highway driving, K&N recommends replacing the KNA-2364 every 18,000 miles. If you regularly drive in dusty or off-road conditions, inspect the filter more frequently and replace earlier as needed to protect your engine.

• Replace every 18,000 miles under normal highway driving
• Inspect earlier in heavy dust or off-road use
• Visual checks are quick: look for heavy dirt buildup or oil saturation
• Follow vehicle manufacturer and K&N guidance for best results
