it takes 5/8 plugs! The r44lts is the recommended replacement for this motor.
to change the spark plugs first take off the plastic cover on top of the motor, the spark plugs are on the center of motor you see two coils on top of the two center spark plugs and two spark plugs wires going to the out side spark plugs you pull the wires off and you need a long socket wrench or a spark plug socket with extension bar to take it off, also you need to pull the coils to replace the center spark plugs they are under the coils. NOTE. this is for a four cylinder engine. excuse my English B. Cerda.

My 2004 Suzuki DF70 uses NGK BPR6ES plugs.
Take old spark plugs out put new spark plugs in
I heard you have to take half the motor apart to get to them.
a standard 5/8 deep socket spark plug wrench
Take out the 4 bolts on the cover that has 2.3 on it, unplug module on driver side and pull the unit up. There are your plugs.
I have a 1996 Chevy astro w/ 4.3 L vortec... these plugs fit that motor.
easy.........take the old spark plugs out and put the new spark plugs back
you have to take the motor brackets that hook the motor to the front of the car and then roll the engine forward carefully to get to the back three plugs.
when you look at the top of the motor you will see four black plastic caps with wires going to them you need to take them off and you will need a long spark plug remover to get to the spark plugs but that is were they are located
