The KAX CA8918 Premium Engine Air Filter is a direct-fit replacement designed to protect engines in select Toyota and Lexus models by improving filtration and extending service intervals.

This KAX CA8918 unit is engineered as an upgrade over many standard paper filters, using advanced media to trap finer particles while maintaining airflow. It fits a range of Toyota and Lexus vehicles from the late 1990s through the 2010 model year, offering longer service life and consistent engine protection without modifying your intake system.

Which vehicles does this KAX filter fit?

The CA8918 is made to match factory dimensions and seals for specific Toyota and Lexus models. It fits multiple engines and model years so you can replace the original filter with confidence.

• Toyota Tundra 3.4/4.7L (2000–2006)

How does this filter improve engine protection and performance?

KAX uses a multi-layer filtering approach to capture small contaminants while allowing clean airflow. Better filtration reduces the risk of abrasive particles reaching sensitive engine parts, which helps maintain consistent performance and can support fuel efficiency under normal driving.

• High-performance oiled cotton gauze as the main media for enhanced trapping
• Embossed paper layers add crease stability and increase dust capacity
• Reported 99.9% filtration efficiency for improved contaminant capture

How often will I need to replace the KAX CA8918 filter?

KAX designs this CA8918 filter for longer service intervals compared with many standard disposable filters. Exact replacement frequency depends on driving conditions, but the construction aims to extend life between changes.

• Typical mileage guidance: up to about 20,000 miles under normal driving
• Not washable or reusable—replace when visibly dirty or per maintenance schedule
• Packaged as a single boxed unit for easy storage and installation

What are the physical and installation details I should know?

The CA8918 is manufactured to match OEM size and shape so it installs in the factory airbox without modification. It’s a rectangular, boxed filter built to the vehicle-specific dimensions and intended as a direct replacement part.

• Dimensions: 12.1" length × 9.1" width × 2" height; rectangular form factor
• Single-piece boxed packaging; replace the factory element one-for-one
• Not intended for reuse or washing—dispose and fit a new CA8918 at service
