For Wix, new technologies have evolved from new testing arenas. Never service the air cleaning system while the engine is running. Never operate the engine without an air filter. Don't install a damaged filter small tears can have disastrous effects. Air filters for passenger cars and trucks should never be cleaned and re-used.
Check filters regularly.
Holding the air filter up to light can show the amount of dirt trapped and indicate it's time to change your filter. Use only the proper size filter for your car. The wrong size filter may seem to fit but could allow contaminants into the engine. Return to Fall Car Care 1999 main page. Thank you for visiting.
