Do high performance spark plug wires make a difference?
High performance spark plug wires are made to provide a lower core resistance, a greater resistance to engine heat and chemicals, and a higher degree of radio suppression. The wires also have heavier outer materials to prevent damage from heat and chemicals, and provide better radio frequency suppression.
How many ohms should a good spark plug wire have?
Question: How many Ohms of plug wire should be used? Answer: Usually between 10,000 and 12,000 ohms of resistance per foot of wire.
Why do spark plug wires have so much resistance?
The resistance of many wires is measured in ohms per foot. Lower resistance means more of the ignition coils energy is going towards bridging the gap or the spark plug. That hotter spark can create a more even burn of the fuel/air mixture in the cylinder, and thus, more power output from the engine.
Why does my spark plug wire keep arcing?
It can jump from a weak part in the insulation of the wires or boots or it can arc internally in the coil, damaging it. This is why it is important to change the plugs as well, and to always change them according to the maintenance schedule.
What does arcing from plug wire to ground mean?
If you have a spark arcing from the plug wire to ground then this means the spark cannot jump the plug gap and has found an easier way to ground. This normally means a defective spark plug or there is something going on inside that cylinder (s) (low compression, too rich, coolant, etc.) to kill the plug (s) while it’s under compression.
How can I tell if my spark plugs are too close together?
To best see any sparks, run the engine in a dark place and watch the spark plug wires and the ignition coil . Spark plug wires which are too close together can INDUCE spark in each other. Are yours bound together?
Is it wise to replace all spark plugs, Spark plug wires?
Will it be wise to replace all spark plugs, spark plug wires Yes, if one set of wires is starting to arc, odds are the others aren’t long behind it Yes,change them…thats an easy doityourself project. All you need to do is identify where all the wires go.
