How do I install new sparkplugs in mitsubishi montero sport?

First you have to remove the upper intake plenum and most everything attached to it coils hoses throttle body brackets .then remove the plug wires from the plugs ans change the plugs make sure you use only denso or ngk iridium plugs install them install plug wires then the plenum, its a chore the first couple times just make sure you mark anything if you cant remember where it goes and you do not have to remove the t'body from engine just take the four bolts out and push it out of the way
