Yes, take off the air hat. I also found it helpfull to disconnect some of
the coolant lines that came across the top of the engine (they didn't leak
out when I disconnected them). Using two long extensions can help avoid
bloody knucles. I used a spark plug socket (the one with the little rubber
insert) to remove the plugs. As a backup I had one of those special tools
to grab things in tight places ($1.99 at the traveling tool show) as a
backup. Also, be gentle with the harnesses for the direct ignition modules
over each spark plug the plastic tabs break pretty easily.
I think plugs are kinda like the tires and shocks. The factory stuff is
really cheap to keep the cost of the truck on the showroom low. You'll
probably get an improvement from any decent plug. Personally I got the
Bosch Platinum +4s. Others may recommend these and still others will
recommend different plugs.
