How do you change the oil filter on a 04 Honda civic Si?

To change the oil filter on a 2004 Honda Civic Si, first ensure the engine is cool and then lift the car using jack stands. Locate the oil filter, which is on the underside of the engine, and use an oil filter wrench to unscrew it. Before installing the new filter, apply a bit of oil to the rubber gasket of the new filter to ensure a proper seal. Finally, screw in the new filter by hand, tighten it gently, and then refill the engine with new oil as needed.
