How do you change the sparkplugs and sparkplug wires on a 91 subaru legacy?

Hey, is this something that a guy like me with VERY little automotive experience( I think I can change the oil and put coolant in, but thats about all i've done) can pull off, or will I have to take it in? if someone knows of an online resource that has diagrams or something for how to do this please let me know.

That would depend on how accessible the spark plugs are......... If you can see all of them and can get to them with a spark plug socket and ratchet, it shouldn't be too difficult. Make sure to check the spark plug gaps before you install them.... they aren't always right when they come out of the boxes. Change the spark plugs first, and then the wires..... one at a time.. to keep from messing up the firing order. Match the length of each plug wire with a new one, and route them the same way that they came out of there. I think that was an aluminum head on that engine.... you need to be very careful not to over tighten and strip the threads out of the spark plug holes.
