I just did the Oil in our 2007 SI for the first time. My god does honda make the WORST oil filter setups ever. The oil filter is on the back side of the engine, directly below it is the axle, control arm, chassis and some plastic guard. Oil hits all of them and gives a nice 1.5 sqft shower. Why does honda do this? Its the same way just not as bad with my TL, it hits 2-3 things on the way down. Only thing I cant think of is Honda makes a point to get people pissed off with the big mess it makes so people will take the car into them for service.
