So I recently bought my first Lexus, a '93 GS300. Looks and runs brand new, but It didn't pass smog.. I fixed an exhaust leak on it, changed the cap and rotor, and I am currently in the process of changing the spark plugs. I got the Throttle Body out of the way and everything, but when I went to take out the Spark Plugs, they wouldn't budge; and by the looks of them they are the same Plugs that originally came with the car back in 1993. I know I can still get them out, but I'm Very iffy about forcing them out because I don't want to destroy the threads.. So can anyone give me some suggestions or just some Info that might that might make this a little easier on me? I'd greatly appreciate it,

I would try to LIGHTLY tap on the extension piece with a hammer. Just to loosen the corrosion.

Or you can get a can of liquid wrench and spray some down there. Put a long pipe over the ratchet's end and slowly rotate the ratchet and socket from the far end of the pipe. This will require far less effort, and make it seem like you are putting 3-4 times more effort at the same time.

Its all dynamics and moments from school.

Tapping the extension is not horrible, but I would resort to that last as it is an aluminum head and cylinder pressures do get high under combustion. So too much free play in the threads could be bad.
