Re: air filter
Is it made of sponge.You can clean it in some warm water with detergent and squeeze it out afterwards ,dry it ,then lightly oil it. I've seen them cleaned in petrol too. If your car is late model then you need to be careful with the amount of oil used on the filter because it takes very little to make it's way to the Air Flow sensor and dirty it.
