On older cars with carburetors the filter is usually under a bulky, round cover made of plastic or metal. Newer, fuel-injected cars tend to have a square or rectangular air filter housing can be found slightly off centre between the front grill and the engine.
Seal the air conduit with removable adhesive tape. It only takes a minute and that way you won’t get any dirt into the engine whilst cleaning.
Make sure it’s on straight and securely; otherwise you could alter engine performance. Tighten all the screws or clamps and recheck that you have put everything firmly back together by rocking the unit gently with both hands. Shut the bonnet securely.
