I have a K& N air filter which I clean every 60,000 kms. Just wondering ive had the car since it only had 45,000 kms on it. What else should I be checking/doing for maintenance on it with approximatley 190,000 kms on it now. Like other then regular oil changes. Is it time to do an engine flush? And wondering what else I should be doing on it. I have also replaced the spark plugs and wires at about 160,000 kms so there fine. As well as the main drive belt, battery, and alternator have all been replaced, their fine also.
