how difficult is it to change plugs /wires on 2002 subaru impreza 2.5rs?

Answer 1

Its fairly easy,remove air intake boot and baffle on passenger side and washer bottle on drivers side.Remove wires and match for length one at a time.Reinstall with silicone spray on plug end.May have to pull pretty hard to get old ones off,esp. if they are original.You may be able to do them w/o removing air intake boot and washer bottle,but is easier with them out.
