1 Determine what type of wires you want to use
2 Determine if you want custom fit wires, or if you wish to use standard wires.
3 Decide how much you wish to spend. Standard wires offered by aftermarket dealers are usually inexpensive, but may not last as long or meet the original manufacturer specifications.
You want 8mm or larger wires. Look at how the wire is crimped inside the rubber boot ends. Cheap ones are hardly crimped. Good ones will smash the wire covering almost half way.
Wish you had listed the year make and model car application. Do an ignition wire OHM's test to see what the resistance is.
Buy OEM's , Bosch, Accel, ACdelco
you just buy what the car calls for ! if you tell the parts man what kind of car and the size of the engine then he will give you what your car calls for ! but get the ones that are already put together ! if your car calls for 7mm then those are the kind you need ! if it calls for 8mm then you buy those kind !
