there is a thing on which its written 'DOHC 16Valve'...you'l see 4 screws at 4
corners...if those screws are undone, you will find a pair of ignition
coils...they are of 'T' shape...the long end going inside the head to top the
spark plugs...they basically transfer charge from the battery to the spark
plugs...A VERY HEAVY VOLTAGE CHARGE ACTUALLY. SO DO NOT PLAY WITH IT WHEN CAR IS
