with the stock air box on, i hosed the entire engine, everything and everywhere. have done it 3 times to this car, and both of my last 2 trucks. dont use a real power washer, it can rip wires apart.
de grease, and hose it down with a full force garden hose with a spray nozzle.
after the first go around, if you see any greasy areas, re spray and hit it with a stiff paint brush or what ever you got to scrub with that will fit where you need it to.
if you have a compressor, blowing all the water of everything is nice, but not needed.
