No offence intended but you need a manual if you are asking this question. But in the mean time, your filter is located just under the intake manifold. If you have just opened your hood and are standing in front of the car, you'll want to look straight back at the fire wall then go down below the intake manifold and look at the block there you will find the filter. You will want to get under the car to change it though. The drain plug is the bolt protruding from your oil pan, the big black tub on the bottom of your motor.

Follow the previous advice and change out the crush washer before you put the drain plug back in or it will leak. When you put the new filter on, I don't know about the need to fill it up but be sure to lube the rubber seal by just running some oil around it with your finger. Hand tighten the filter until the rubber seal makes contact the use a filter wrench to tighten it aprox. 3/4 turn.

My h22 takes about 5.1 quarts to fill so buy six qts so that you have enough. I fill mine until it sits right at the full/max mark on the dip stick that way when vtec kicks in, it gets good oil pressure
