igniter. go to the dealer and make SURE you get the BROWN one, NOT the black one. it is inside the distributor and is very easy to change. when you go in there, make sure you turn the engine by hand and not with the starter, when you're trying to line up the screw on the rotor. i blew my coil on my gsr by using the starter. the igniter should run anywhere from $80 - $150.
