The oil filter housing is located (passager side) on the engine under cyclinder one behind heat shield. Air filter housing has to be removed. Got my oil change at Henry Oil Can for $120 (regular car $80 but A8L take 8 quarts) or forumla one for same price. They don't know where the filter is you have to tell them.
