Are 8mm spark plug wires vs 7mm?

Are 8mm spark plug wires vs 7mm?

8mm spark plug wires are a heavier gage wire than the 7mm type. However, there is more to it than just the difference in the thickness. The thicker wire has a thicker core. A more robust core provides a lower resistance path for the power, thereby allowing more power to reach the spark plugs.

Are thicker ignition wires better?

Thicker conductors are required to carry more amps, but spark plugs are fired with very high voltage and low amperage. The thicker wires do have better insulation, usually silicone and that stands up to the heat of the engine compartment and higher voltage from modern ignition systems better than the older wires did.

What’s the difference between 7mm and 8mm spark plug wire?

For instance, 7mm, 8mm, 8.8mm, and 10mm are typical wire diameters. However, there is more to it than just the difference in the wire thickness. “The difference between 7mm, 8mm, 8.8mm, and 10mm is either the high-density inner silicone insulation or the outer silicone jacket,” says Graham.

What’s the average size of a plug wire?

You’ll see a lot of diameter measurements thrown around regarding plug wires. For instance, 7mm, 8mm, 8.8mm, and 10mm are typical wire diameters. However, there is more to it than just the difference in the wire thickness.

What kind of wire do I need for a spark plug?

Our 8mm custom fit MAGX2 wires provide enhanced RFI suppression and dual current paths for more power delivered to the spark plug. Our custom wire sets have factory terminated ends for a superior connection and perfect fit without cutting, crimping or splicing. This opens in a new window.

Are there still two types of plug wires?

“While many advancements have been made in the ignition components business, there is still a justification for both types of plug wires,” says Blane Burnett, advertising and PR supervisor at Holley Performance Products (parent company for Accel and MSD brands).

Can you fit 8mm spark plug wire in a 7mm separator?

The outer casing of 8mm plug wire can be difficult to fit in wire separators designed for 7mm wire.

What’s the difference between 8mm and 7mm wire?

We’ve designed our 7mm wires with the same core we use in our 8mm wire. The only difference is the 7mm flat black silicone jacket that hides its performance potential from the naked eye. Get the best of both worlds with “state-of-the-art performance and a stock look”. These wires will fit most original wire looms.

What kind of spark plug wire do I Need?

If you maintain your car as a piece of mechanical equipment and not a looker trophy , 7mm wires will do the job until the cows return home .
