Why Choose a Reusable K&N Air Filter?

The K&N reusable air filter is designed to provide long-term value by eliminating the need to repeatedly purchase replacement paper filters.

Benefits

High-Flow Cotton Gauze Filtration

This replacement filter uses multiple layers of oiled cotton gauze that are engineered to balance airflow with effective filtration.

Construction

• Multi-layer cotton gauze media
• Factory pre-oiled
• Flexible sealing edge
• Durable molded frame
• Designed for repeated cleaning and re-oiling
• Precision fit for the factory air box

Important: Always re-oil the filter after cleaning. Operating the filter dry can reduce filtration performance.

Factory Drop-In Installation

No intake modifications are required.

Installation is as simple as replacing your factory paper filter.

Installation Highlights

• Fits inside the original Toyota air cleaner housing
• No cutting or permanent modifications
• No ECU tuning required
• Uses existing factory clips and hardware
• Maintains the stock intake system

Performance Benefits

A clean, high-flow air filter can help maintain proper engine airflow and reduce intake restriction.

Potential benefits include:

• Improved airflow
• Responsive throttle feel
• Reduced intake restriction
• Long service life
• Excellent choice for stock or lightly modified vehicles

Actual results vary depending on engine condition, maintenance, altitude, exhaust system, and other vehicle modifications.

Why Replace Your Engine Air Filter?

A properly functioning air filter helps protect your engine from dirt and debris while maintaining efficient airflow.

Replacing a dirty or clogged air filter may help reduce:

• Restricted airflow
• Sluggish throttle response

• Excess dirt entering the intake system
• Premature engine wear caused by contaminated intake air

Routine inspection is especially important for vehicles frequently driven on trails or unpaved roads.
