A clean air filter keeps the Royal Enfield Meteor 350 breathing freely — better throttle response, smoother running and better fuel economy. Check it at every service; replace it when it’s dirty or damaged.
On the Meteor 350 the filter sits behind the right-side panel. The job takes 15 minutes with basic tools — just keep track of the screws.

How to clean and replace the air filter, step by step
- Remove the right-side panel — undo the screws and set the panel aside.
- Take out the filter — lift it out of the airbox; note which way round it fits.
- Inspect it — hold it up to the light: if you can’t see light through it, it’s time to replace it.
- Clean the airbox — wipe out dust and debris before fitting the new filter.
- Fit the new filter — seat it correctly, making sure the seal is even all round.
- Refit the panel — tighten screws snugly, don’t overtighten.
- Start the engine and check it runs smoothly — a poorly seated filter lets unfiltered air in.
Common mistakes to avoid
- Re-oiling a paper filter — paper filters are not designed to be oiled — replace them instead.
- Running without a filter ‘for more power’ — unfiltered air wears the engine fast — never ride without a filter.
- Over-oiling foam — too much oil restricts airflow and can foul the plug — oil lightly and evenly.
- Forgetting to clean the airbox — dust left in the airbox ends up in the new filter — wipe it out first.
