Maintenance and Parts Replacement Cost

Hi guys, I have a 2004 model 1.6 petrol 307 envy car. I will have my vehicle serviced for winter and spark plugs oil, gas filters etc. I'm thinking of changing aceba, I would appreciate if friends who know how much it costs me. Lately, my car has been singing, I am running on the road, but it does not eat gas. There is a lot of gas smell and it removes the gas from exhaust. While the vehicle is running at idle, the engine vibrates too much and shakes like a sieve.

Spark plugs are $ 11

Filters 45 TL, if you want to buy the gasoline filter separately around 15 TL

Workmanship varies according to provinces 20 to 50 TL.
Use the filters absolutely original in maintenance, all the products I link are original.

I don't know if the issue is in the wrong place, but ... does the change of spark plugs and air filter affect fuel? What is the importance of spark plugs in fuel? How do we know if the spark plug needs to be replaced?

One of the spark plugs function. If it is not visible, the vehicle will be knocked. The antipollution fault error may also appear on the screen. I usually replace spark plugs in 2 servings.
Air filter has a direct effect on the fuel.
