Q: Want to change the spark plugs and seem to need to get the cover off to access #2 and #3 plug. i changed the plugs with out removing the engine cover, it would still be nice to know how though
A: That is not a cover, its the plenum for the intake manifold. Thats good that you didn't remove it to change the plugs there is no need to. But if there is ever a time you need to the front has i think its five or three #5 allen/hex key bolts and the rear has one #6 allen/hex key that hold up the plenum. Hope this helps out.
