Yes, you have to remove the splash shield under the engine; about 6 or 8 screws.
To remove the oil filter cap (this car uses a cartridge type filter) you will need a special oil filter wrench. There are specialty wrenches that sell for many $$ but I found one that was a perfect fit at AutoZone. It is sold under the OEM trademark and is called "Oil Filter "B" Cap Wrench". Only cost a few dollars.
