dont force them you can ruin the threads in the block... look at them next to each other do the threads match? Im not trying to be a smarta$$ but if they dont match then the auto parts store gave you the wrong plugs.

Try to run them in the threads of the block by hand until they get a proper grip... you shouldn't be having any issues, post the part number and brand of the spark-plugs you got. Also fill up your signature so we can know wich engine you have.

I do know that the plugs for the 302 explorer have a long/short thread version, but both are interchangeable.

Sorry, but somebody's gotta do it:
#1. Righty/Tightly
#2. Lefty/Loosey
I think you've forgotten, the plugs don't all screw in perpendicular to the block. Stick your pinky finger, or something else you can't loose down the hole, & identify the correct angle of attack for each plug.
