Introduction ------------ [Go to step 1](https://www.ifixit.com/Guide/2018+Honda+Civic+LX+Engine+Air+Filter+Replacement/167874) An efficient working engine air filter will clean the air entering your engine so that the air used to ignite your fuel is clean and free of dust, dirt, soot, or smoke. To find out if your filter needs to be replaced, look for signs such as dirty filters, a decrease in gas mileage, engine misfires, strange engine noises, and check engine lights or potent fuel smells. This guide provides step-by-step instructions for a successful engine air filter replacement on a 2018 Honda Civic LX.
