Long extension, swivel, magnetic, thin walled sockets are a life saver on anything that has a dohc or single cam with the plugs buried under the valve cover.
That being said back in the day you could duct tape the sockets/extensions together then insert a piece of 1/2" hose to extract and get the new plug started.
The situation depends on the tool.
I have had engines stuffed in bays tight enough where the header is 1/8" off the firewall. In that situation another "special tool" called a pass through ratchet was used to break the plugs free then remove and insert them by hand.
Rules would not let me use my "special tool" called a hole saw or I would have.
People complain about foreign junk. But the simple fact is when a special tool that you only need to use once or twice cost $60+(dealership/sears) it was hard to justify buying. Now you have places like HF and auto parts stores that stock such items where special tools have become common place at a fraction of the price and headaches are reduced.
