I'm guessing you're asking because it's a v6 FWD and you don't know how to get to the spark plugs along the firewall. you will need to find the front motor mounts or the anti torque bolts whatever you wanna call it and make your motor swing. you can do that by locating your front motor mounts or side or even rear. i'm not sure with a eclipse but once you've found the anti torque bolts attached to it and removed them you can roll the car forward and it should leave about 6 inches of space behind the engine to get the those spark plugs. front should be easy
