Air Filter Cleaning – Replacement Guide for 2020 Husqvarna TE300i
Shop parts for a 2020 Husqvarna TE300i Dirt Bike.
The 2020 Husqvarna TE300i features an advanced fuel-injected two-stroke engine designed for top-tier performance in off-road conditions. Its air filtration system is engineered for maximum airflow while preventing the smallest particles from reaching the engine. Meticulous air filter maintenance is critical for both performance and engine longevity. Below is MotoSport's definitive, model-specific guide to air filter cleaning and replacement for your TE300i.
Understanding the Filter Design
The TE300i uses a high-flow foam air filter mounted inside the airbox, easily accessible thanks to the bike's tool-less quick-release system. Pay attention to fitment–incorrect installation can allow debris to bypass the filter, causing damage to the engine and fuel injection system.
Necessary Supplies
- Nitrile gloves
- Foam filter cleaner (biodegradable for biodegradable oils, solvent-based for standard oils)
- Quality foam filter oil
- Clean towels or rags
- Plastic tub or zip-top bag
- Replacement filter, if needed
Step-by-Step Cleaning – Oiling Process
- Preparation: Remove the seat. Carefully release the air filter from its mounting tabs – press the tabs and slide the filter out with its cage.
- Initial Inspection: Note the position and condition of the filter. If it is excessively dirty, torn, or the sealing surface is degraded, replace immediately. Always verify cage and seal integrity.
- Cleaning the Filter:
- Gently tap the filter to remove loose dirt outside the airbox before handling. Avoid dropping debris into the intake tract.
- Apply air filter cleaner liberally or soak the filter in cleaning solution. Work the cleaner through; do not stretch, wring, or tear the foam.
- Rinse in clean water until free of dirt and cleaning residue. Squeeze gently–never twist. Repeat cleaning if necessary.
- Let the filter dry completely (air dry in a dust-free environment).
- Oiling:
- Pour or spray ample filter oil onto the clean, dry filter. The oil should saturate the entire filter, inside and out. If using a tub or bag, knead the oil into the filter until fully absorbed. Properly oiled filters will drip slightly when squeezed, indicating full saturation.
- Work the oil around all pleats and seams. Avoid bare, lightly oiled, or dry patches.
- Hang the filter for 30 minutes to allow excess oil to settle and ensure full coverage before installation.
- Reinstallation:
- Wipe out the airbox with a clean, damp cloth. Inspect the seal surface for dirt remnants.
- Install the filter and cage carefully, aligning the mounting tabs so the filter sits flat—there should be complete contact around the sealing edge for the TE300i's intake layout.
- Make sure the filter does not deform during installation and that the cage is properly locked in place.
Model-Specific Tips for the 2020 TE300i
- Check the air filter cage for signs of warping or cracking; even minor distortion can let air bypass the filter. Some riders have reported fitment inconsistencies, so confirm the filter seats securely around every edge.
- The TE300i's fuel injection system is more sensitive to unfiltered debris than carbureted models. Never run the bike with a damaged or poorly fitting filter.
- Avoid using excessive oil, which can clog the injector or restrict airflow. However, under-oiling–especially with aerosol oils–is a common mistake. Work the oil in until a slight drip appears when squeezed, but do not soak to the point of puddling inside the airbox.
- Always inspect the airboot for obstructions and the rear of the filter for telltale dust trails, which can reveal leaks or airbox damage.
Replacement Schedule – Pro Tips
- Clean and re-oil your air filter after every dusty ride, race, or any time you notice diminished performance.
- Carry a pre-oiled spare for multi-day events or long rides–quick swaps in the field prevent dust ingestion.
- Replace foam filters after several cleaning cycles or if any visible wear, tears, or permanent deformation is present.
Keeping your Husqvarna TE300i's air filter fresh is one of the best ways to preserve engine life and dominate every ride. Use only quality filter products and follow a strict service interval, and your TE300i will continue to deliver class-leading performance.
