What is the diameter of a spark plug wire?
Plug wires are most often rated by their diameter. The most common are 7mm and 8mm thicknesses, but what’s more important is the conductor. The best choice is the spiro-wrap style Taylor wires that reduce resistance, minimize RFI noise, and offer the best performance.
What size is plug wire?
Size is perhaps the last thing to consider when it comes to spark plug wires. Most manufacturers recommend an 8 or 8.5mm plug wire on most applications. Exceptions would be an all-out race car or a street rod where EMI/RFI suppression is not a concern, but weight and appearance are.
Do thicker plug wires make a difference?
There isn’t any performance to be gained from spark plug wires, just better build quality, which gives you not a better spark, but rather maintains an appropriate spark for more miles/years before their performance degrades to the point of needing replacement.
What is the difference between 8mm and 10mm spark plug wires?
Well, there are many diversities in plug wires. They vary from 2 mm to 12 mm range. But not all of them are useful on a regular basis. 8mm, 10mm are the most popular ones….A Short Table: 8mm Vs 10mm Spark Plug Wires.
| Topic | 8mm Wires | 10mm Wires |

How big should a spark plug wire be?
Plug wires are often advertised by the diameter of the wire, making it easy to look at the options for plug wires and immediately think if 7mm is good, 8.8mm must be great. There is more to consider though.

What did spark plug wires used to be?
Early spark plug wires were very simple—just metal that conducted. There wasn’t even insulation. The automobile had been around for at least 50 years when my 1930 Ford Model A was built, and guess what, it’s plug wires are just straps of metal from the distributor to the plugs.
Why do I need a lower resistance spark plug wire?
The higher voltage of a coil on plug or distributor system can create enough voltage that a slightly higher resistance wire will not greatly affect spark strength, but the relatively lower output of a magneto means using a lower resistance wire is more important to ensure a hot spark from the spark plug.
