There is a cover down the center of the valve cover that has to be removed to gain access to the three ignition coils and six spark plugs in your engine. The air filter is straight forward to replace, the plugs are easy, your car's engine has hydraulic valve lifters (not necessary to adjust the valve clearance) and a timing chain so you don't have timing belt replacement to worry about as a maintenance item to worry about.
Buy a workshop manual and see how confident you feel before undertaking any repairs.
