USe a good degreaser, let it sit of a few hose it off after. Might need a brush for some of the hard to remove grease. Blow it dry with an air hose after your all done.
Actually, even with the spark plug cover, there is a tendancy for water to seep down into the spark plugs.... Just don't make a point of spraying around the plug wire cover really hard... I had that happen to mine once...
No big deal if it happens, just pulled the plugs and let it dry out....
