The 2024 GAS GAS EX450F features an advanced, easy-access airbox system designed for quick, tool-free air filter maintenance. Keeping your air filter clean and properly installed is essential for peak performance – dirty or poorly installed filters can restrict airflow and allow harmful debris into your engine. This guide covers removal, cleaning, inspection, oiling, and installation tailored specifically for your EX450F.

Key Features & Considerations for the 2024 EX450F Air Filter System

  • Tool-free access: The airbox allows easy filter changes without tools, thanks to a practical quick-mount system. This minimizes downtime and encourages frequent maintenance. 
  • Engineered for power: Precisely placed intake ducts in the airbox maximize horsepower by ensuring smooth, clean airflow. 
  • Recommended filter type: The EX450F uses a dual-stage foam filter (like Twin Air), optimizing protection and high airflow. Always use high-quality, model-specific filters for best results.

Step-by-Step: Air Filter Removal

  1. Remove the right side panel: Gently detach the right side panel to expose the airbox. Follow the panel release points to avoid damage.
  2. Access the air filter cover: Open the air filter box cover. The 2024 EX450F design allows this step without tools.
  3. Remove the air filter: Carefully pull out the air filter and filter cage. Note filter orientation to ensure correct reinstallation.

Cleaning the Air Filter

  • Avoid gasoline or petroleum products: Never use these as they degrade foam and adhesives, shortening filter life and compromising engine protection.
  • Use a dedicated foam filter cleaner: Gently massage the cleaner through the foam. Rinse thoroughly until all debris and old oil are removed.
  • Dry completely: Let the filter air dry entirely. Never use high heat or open flames.

Inspection & Oiling

  • Inspect for damage: Look for tears, splits, or deterioration. Replace if compromised – clean air is crucial.
  • Apply high-quality air filter oil: Evenly work filter oil into the foam (do not over-saturate or leave dry patches). Thoroughly squeeze out excess – your filter should be uniformly tacky.

Air Filter Box Cleaning

  • Wipe the airbox: Use a damp, lint-free cloth to clean the inside of the air filter box, removing all residual dirt before refitting the filter.

Reinstalling the Air Filter

  1. Seat the filter properly: Place the cleaned and oiled filter back on the cage, ensuring a perfect seal around the airbox opening. 
  2. Secure the cover and panel: Replace the air filter box cover and reinstall the right side panel, double-checking all fitting points.

When to Clean & Replace?

  • Clean: After every few rides, or more frequently in dusty/sandy conditions.
  • Replace: At least 1-2 times per season, or immediately if the filter shows any sign of damage.

Special Tips for Your 2024 EX450F

  • The airbox's direct, streamlined design helps maximize horsepower, so never operate with a poorly sealed or dirty filter.
  • Only use foam filter oils compatible with the manufacturer's adhesives for the best longevity and seal.
  • Check intake ducts for obstructions when the filter is removed – the EX450F's efficiency depends on unrestricted, clean airflow.
