NAPA plug wires good to suppress radio noise?
I have a 1980 Jeep CJ-5, V-8 engine. I just use it at my vacation cabin. I have terrible ignition noise on the am radio. I have replaced the plugs, rotor, and distributor cap. I have not replaced the plug wires. There is a NAPA dealer in the nearby town. Does NAPA sell a basic good set of plug wires, that is effective in radio noise suppression?? I know I can call NAPA and ask, but I prefer to get input from other persons that would have first-hand knowledge about this sort of thing. Thanks for any help !! --James-- |

check main ground, radio ground and antenna ground before changing the plug

Re: NAPA plug wires good to suppress radio noise?
I like to buy my plug wire on the roll, and use the resistor terminal.
Usually if you use the resistor plug in a vehicle with a steel firewall and hood you get little noise. Are you sure it's ignition noise and not the alternator? NAPA people generally don't know their ass from a hole in the ground, although there are exceptions. |

Re: NAPA plug wires good to suppress radio noise?
First, make sure your spark plugs have an 'R' in their model number.
That means they are a resistor type spark plug that reduces radio ignition noise without reducing spark output in a significant way. For spark plug wires, make sure to avoid ANY ignition wiring sets that brag about low resistance since that is, like on the spark plugs, needed to suppress AM radio noise. Due to how wiring and Ohm's law works, the resistance needed in ignition wiring and spark plugs to eliminate ignition noise in an AM radio does not significantly reduce the spark intensity. There is so little current flowing through ignition wiring that even the normal high-resistance in ignition wiring does not significantly reduce the voltage. And don't worry, that extra resistance is PURPOSELY added to the wiring... it costs more to make it that way than it would with lower resistance wiring. So go with standard carbon-impregnated ignition wiring sets and avoid at all costs any so-called "performance" ignition wiring set that talks about its lower resistance even if it also says it has some lame "spiral-wrap" technology to reduce noise. Using standard resistance-type spark plugs and ignition wiring should take care of your ignition noise in your AM radio. Jerry James Nipper wrote: > I have a 1980 Jeep CJ-5, V-8 engine.
