WHERE IS THE OIL FILTER

I need help. I am wanting to start changing the oil in my wife's 99 EX (4 cylinder). I have tried to locate the oil filter before doing so and can not. Can someone help me out here as to what side and the best way to get to it?

sure thing. It's under the intake manifold on the back of the engine block. The best way to get to it is from under the car. Hope this helps!
