BMW R 1300 GS Air Filter Cleaning and Replacement

The R 1300 GS breathes through a paper air filter tucked under the fuel tank, and a clogged one quietly robs power and economy. BMW’s service schedule calls for an inspection at every service and replacement when dirty — dusty riding shortens that interval fast.

This guide shows you how to reach the airbox, clean or replace the filter, and avoid the common pitfalls — in about an hour with basic tools.

How to clean and replace the air filter

1. Remove the seat and side panels, then lift the fuel tank enough to reach the airbox.
2. Release the airbox clips and lift the lid clear.
3. Lift out the filter element and inspect it against a light — if you can’t see light through it, replace it.
4. Tap out loose dust, or blow it out gently from the clean side with low-pressure air.
5. Wipe the airbox clean and check the drain for debris.
6. Fit the new or cleaned filter the same way round, refit the lid, and torque the clips evenly.
7. Lower the tank, refit the panels and seat, then start the engine and check the idle.

Common mistakes to avoid

• Using high-pressure air, which can tear the filter paper.
• Leaving the airbox lid unseated, which lets unfiltered air into the engine.
• Forgetting to check the airbox drain after riding in rain.

FAQ

How often should I replace the R 1300 GS air filter?

Inspect it every 6000 miles and replace it every 12000 miles — or sooner in dusty conditions.

Can I clean a paper air filter?

You can tap or blow out loose dust, but a paper element can’t be washed. Replace it when it’s dark or damaged.

Will a dirty air filter hurt fuel economy?

Yes — a restricted filter makes the engine work harder and can raise fuel consumption noticeably.
