hey i bought a jdm itr dizzy from him today and tried to put it on, didnt work so i tried my brothers car. same, we believe it was the coil but we replaced it with another and didnt work. seems to be something internally, anyways i calld him back up and told him what happen. he was simply surprised and said he will return my money tomorrow same time no problem. these are the type of people i like dealing with!! honest and a reliable guy! hope to do business again.
