Air filters are the parts that protect the engine from outside contaminations and pollutants like pollens, dust particles, etc. They increase the life of the engine and help its smooth performance. But the timely replacement of air filters is crucial. In general, we advise you to change them after about 20,000 to 35,000 kilometers or as mentioned in the user manual. 

If you don’t replace the air filters on time, you may face:

• Increased fuel consumption
• Reduced performance of the engine
• Issues with the spark plug
• Unusual sounds 
• Black, sooty smoke from the exhaust

There can be some other major or minor issues that will lead to more expenses and hassles. To avoid all these, we strongly recommended getting the air filter checked regularly and replace it as soon as needed.
