Toyota Corolla AE80 with a 2A Engine and i’m about to change spark plug. Any idea for the specification (gaps, thread size). Lost my manual.?

Go to the Parts Store, tell them what you have, ask for NGK Platinums ($4-5), ask what the gap is and check them. Apply thread lube if it's an Aluminum Head. Don't make this harder than it is.

The car part store will show a list of correct spark plugs for each engine. It's their work to find and sell the correct parts when you tell what car you have. Don't buy spark plugs online. Go to the store. Go on. Get up and do it. If you insist on knowing this, go to the public library and look in their car repair manual. Xerox the info and keep it in the glove compartment. Remember you put it there for the next time- years from now.

That information wouldn't be in the owner's manual anyway. If you want to do work on your own car, buy a SERVICE MANUAL

since you did not include the year of the vehicle, all "we" can do is guess..............you need to do a google search for the exact make, year, etc to get the proper gap info

Why didn't you ask when you brought the plugs they will be gaped correctly anyway I've never needed to change the gap on any plug Ive brought unless its been dropped on the ground. Ill guess 1.5mm

Just buy NGK or Denso Iridium spark plus. They com pre-gaped.
