How much is the Pentium x80 throttle inlet?

Hello, car owner, 40,000 kilometers need to replace the spark plug and clean the throttle nozzle. There are rules, but please don't say. If it runs without any problems and does not consume any oil, you can do it together with major maintenance. 60,000 kilometers can carry out major maintenance, replace the vehicle oil, engine accessory belt, replace the spark plug, clean the throttle nozzle, clean the three-way catalytic converter, air inlet and replace the gasoline filter. I hope I can help you.
