The air filter on your 2019 Husqvarna TE250i is critical to engine performance and longevity, especially in off-road conditions. Proper cleaning & replacement keeps your bike running at peak power while protecting the engine from harmful dust and debris. Unique to this model is the tool-less access to the air box, simplifying routine service. This guide from MotoSport delivers a step-by-step, owner-focused process tailored to the TE250i.

When to Service the Air Filter

  • Check after every ride in dusty or wet conditions.
  • Clean or replace if you notice reduced throttle response, visible dirt, or at suggested maintenance intervals in your manual.

Preparation – What You Will Need

  • Replacement or clean foam air filter
  • High-quality filter oil
  • Air filter cleaner or biodegradable solvent
  • Latex gloves (highly recommended)
  • Clean rags
  • Water resistant grease

Removing the Air Filter

  • Make sure the bike is off and cool.
  • Open the left side panel for tool-less access to the air filter compartment. The TE250i design allows for quick release without extra tools, a notable advantage of the 2019 model.
  • Ease the filter out, noting orientation for reinstallation. Avoid dropping debris into the air box during removal.
  • Carefully inspect the filter cage and air box for any visible dirt.

Cleaning the Air Filter

  • Gently work the foam filter free from the frame or cage.
  • Massage the filter in air filter cleaner or solvent, kneading without wringing out to prevent tearing.
  • Rinse with clean water until all cleaner and dirt are gone.
  • Allow the filter to dry completely before applying oil.

Oiling – A MotoSport Best Practice

  • Apply high-quality foam filter oil evenly, ensuring full coverage but not over-saturating.
  • Work oil in by hand for uniform protection. Excess oil should be dabbed off to prevent dripping onto the air box or swingarm.
  • Use water resistant grease to lightly coat the edge or sealing surface of the filter. This critical step prevents unfiltered air from bypassing the filter and entering the engine.

Inspect the Air Filter Cage & Box

  • Check the filter cage for cracks or damage. Clean thoroughly with a rag.
  • Wipe out the air box – a uniquely easy task on the TE250i given its open access design.

Installing the Air Filter

  • Remount the clean, oiled filter onto its cage. Ensure all prongs and tabs are properly aligned for a solid seal.
  • Fit the assembly back into the air box, pressing gently around the sealing surface to verify a complete seal.
  • Double-check the filter is seated correctly and no edges are pinched or loose.
  • Reinstall the side panel.

2019 TE250i Model–Specific Tips

  • The air box is compact, and big hands may find space tight; deliberate movement prevents accidentally dislodging the battery.
  • When shifting the battery out of the way, avoid pulling the cables too hard or accidentally grounding terminals against the frame.
  • If you flip out the battery, be aware that the clock & trip meter may reset.
  • Always replace the filter if it is physically damaged or if the foam feels brittle.

Finishing Up

  • Dispose of cleaner and old oil according to local regulations.
  • Keep a maintenance log specific to air filter servicing – especially important for bikes used in extreme conditions.

Keeping your TE250i's air filter clean and properly serviced is the best way to safeguard performance and longevity. Trust MotoSport for genuine filters, cleaning supplies, and everything else you need for your 2019 Husqvarna TE250i.
