How to Change Honda Rancher TRX 350 Air Filter 

How often should you change your Honda TRX350 Rancher's air filter? At the very minimum, it should be replaced every time you change the engine oil. 

However, if you want your Honda ATV to perform at its peak, then you should inspect, clean and replace your Rancher's air filter after every couple of outings, especially if you ride in dusty or sandy conditions. Watch the video above and follow the steps below to change the air filter in a Honda Rancher 350.

Honda TRX 350 Air Filter Replacement

Step 1. Remove the seat by depressing the latch under the right rear side and sliding the seat back to release the clip at the front.

Step 2. Release the four spring clips from the airbox and remove the lid.

Step 3. Loosen the clamp from the front of the filter and remove the air filter assembly.

Step 4. Remove the foam air filter element from the inner air filter frame.

Step 5. Inspect the air filter element. If it's split, damaged, or clogged with dirt, replace it. However, if the air filter is in good condition, clean and reuse it.

Step 6. Take the new foam filter element (or the existing filter after it's cleaned) and spray it with foam filter oil. Completely coat the filter and gently rub the oil into the foam.

PRO TIP: Don't cut corners by skipping the air filter oil treatment. The oil traps tiny dirt and dust particles that would otherwise pass through the filter into your Rancher's engine, which increases wear and shortens the engine's lifespan.

Step 7. Put the foam filter element onto the inner air filter frame, being careful not to tear the element.

 Step 8. Reinstall the air filter assembly into the airbox and re-tighten the clamp.

Step 9. Inspect the rubber seal for any wear, damage or leaks before you reinstall the airbox lid, and replace the seal if necessary.

Step 10. Reattach the four spring clips to the airbox lid, then reinstall the seat and you're done.
