On valve cover

your pcv valve is always in the valve cover and goes to the hose that goes from yourair cleamer to your intake

spark plugs are under valve cover. Each plug has its own coil pack module. Plug is under this. Be ware, factory plugs may have to be ordered ( $ 15 - 20 ea.) , depending on parts stores in your area. here in Canada, some stores had wrong computer listings for all brands of plugs for this car!! The factory plugs are NKG Iridium, and are longer than conventional plugs!! I'm about to change mine ( 160000 KM's).Looked at plugs cpl mths ago, didnt look too bad. Hope to get another 160 K's from new ones ! Good luck .!

Not sure about that car in specific but most cars have their cabin air filters where the front passengers feet would be. There maybe a plastic cover you need to remove and maybe a screw and the filter should drop down.
