2004 hyundai santa fe - where are all of the spark plugs - found 2 but that is it

follow the plug wires from rotor

did you take off the engine cover they should be there and you dont have a rotor

Under the engine cover you will find 3 in the front and under the intake manifold you will find the other 3 towards the back. (Presuming it is a 6 cyl.)

if it is a four cylinder then two have wires running to them & two r coil over plug meaning a black looking box will be on every other cylinder remove them & the plugs r down in the chamber be sure to put di-electric grease in the boots of the wires & the boots of the coils if it is a six cylinder engine then there r three in the front & the other three r under the intake plenum but it is sounds like u have the four cylinder considering u only changed two plugs so far

OK.if it 4 Cly .you got 2 wires and 2 coils. the other 2 spark plugs are under the 2 coil .there all same line just take screws off the coils a left them up your plug is are there.
