You don't need the oil drain plug washers. They come with every oil filter you buy.

Also, why do you need a new oil filler cap? Is the gasket bad?

Also, if you do the 1st time your oil change, I would suggest getting the screw plug for the oil filter element p/n 11427518083 (The O-ring also comes with a new oil filter)
