BMW G310R G310GS (313cc, 2017+) K&N BM-3117 high-flow air filter

Direct-fit, washable, reusable air filter for the BMW G310R and G310GS - same 313cc engine, same mounting, zero mods needed.

• Drop-in replacement for the stock unit; no ECU remap or tuning required
• Oiled cotton gauze media flows more air while maintaining strong filtration
• Sharper throttle response and a more audible induction note on fast-road or track-day use
• Clean and re-oil every 15,000-20,000 miles - saves money vs disposable filters
• Proven fitment on all G310R and G310GS models from 2017 onward
