Most newer model Hondas use saturated 8-10 ohm impedence injectors. Some Hondas, like pre-1992 CRX's and Accords used 2 ohm peak and hold injectors. If you want to use peak and hold injectors on a Honda whose stock injectors are saturated, you can either wire in 7-8 ohm resistors into the injector harnesses, or buy a resistor pack(basically 7-8 ohm resistors encased in insulating ceramic inside a grey metal box) from a peak and hold Honda and wire it into your injector harness.
