Air Filter Cleaning – Replacement Guide for 2022 GAS GAS EX350F

Shop parts for a 2022 GAS GAS EX350F Dirt Bike.

The 2022 GAS GAS EX350F is engineered for demanding off-road conditions, making regular air filter maintenance essential for optimal engine performance and longevity. The unique design of the EX350F supports robust airflow and rapid servicing, but it is especially susceptible to dust and debris—common in trail and enduro environments.

Why Air Filter Care Is Essential for Your EX350F

  • High-Performance Engine: The EX350F's engine is highly sensitive to particulates that restrict airflow and may cause premature wear. A clean filter preserves throttle response and power delivery.
  • Off-Road Exposure: Designed for rigorous terrain, the EX350F's intake system can accumulate dirt quickly, even in moderate conditions.

How to Clean the Air Filter

  • Step 1 – Remove the Seat: Use the quick-release system to access the air box beneath the seat.
  • Step 2 – Remove the Air Filter: Release the air filter cage lock. Pull out the filter gently to avoid dropping debris into the intake.
  • Step 3 – Inspect the Filter: Check for damage. If the foam shows tears or separation, replace immediately.
  • Step 4 – Clean the Filter: Submerge the filter in a dedicated cleaner or mild, biodegradable soap. Squeeze—never wring—the filter multiple times. Rinse until water runs clear.
  • Step 5 – Dry Thoroughly: Allow to air dry away from direct heat sources. Ensure no residual moisture remains before re-oiling.
  • Step 6 – Oil the Filter: Use high-quality filter oil designed specifically for off-road foam filters. Massage oil evenly through the filter. Remove excess oil with a clean towel.
  • Step 7 – Reinstall with Care: Confirm proper positioning in the cage and secure the fastener. Ensure no gaps appear at the seal.

Replacement Guide

  • Replace the Filter every third cleaning or if contaminants persist after washing. Keep at least one spare on hand for race weekends or extended trail rides.
  • Always check for proper seating after installing. The EX350F air box is designed for a tight fit; even slight misalignment can allow unfiltered air in.

EX350F Model-Specific Notes

  • Wide Air Intake: The 2022 model's air intake design enhances airflow but demands frequent inspection of the surrounding air box for debris and minute dust particle buildup.
  • Quick-Release Comfort: The seat and air filter cage use tool-less fasteners for fast servicing. Never force open; inspect bolts and locks regularly for wear.
  • OEM Filter Specs: Always use air filter oil and cleaners compatible with foam filters; avoid solvents and gas, which degrade the filter and shorten engine life.
  • Regular maintenance ensures the EX350F's electronics and sensors—such as throttle mapping—remain responsive. Dirty filters can cause irregular throttle response and even engine stalls.

  • Inspect the air box gasket and filter cage after every ride. Replace if any cuts or hardening are detected to ensure a perfect seal against dirt ingress.
  • Use MotoSport's exclusive air filter cleaning kits for the EX350F to simplify your cleaning routine and prolong component life.
  • Schedule filter checks following any extended, dusty ride—not just after routine intervals.
