Is Thicker spark plug 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 better 7mm or 8mm spark plug wires?

8mm spark plug wires are a heavier gage wire than the 7mm type. A more robust core provides a lower resistance path for the power, thereby allowing more power to reach the spark plugs. Additionally, the 8mm wires have a thicker outer coating that keeps the core safe from damage.

Does spark plug wire size matter?

No, the length of sparkplug wire does not matter. However, The engine will not operate properly without the proper thread reach. If a spark plug with the wrong thread length is erroneously used, the piston or valve could strike it and damage the engine.

Can spark plug wires increase horsepower?

Increases horsepower New spark plug wires can increase your car’s horsepower as well as increase your car’s pick performance. It provides more spark to the firing tip of the spark plug and increases the horsepower.

Do high performance spark plugs make any difference?

Installing high-performance spark plugs can smooth out a rough idle and get your motor purring immediately. Pulstar spark plugs can give your engine more power, a quicker throttle response, and a more stable, longer-lived engine.

What ohm should spark plug wires be?

The Society of Automotive Engineers suggests the maximum resistance should be 12,000 ohms-per-foot. However, some OEMs have recommended different maximum resistances. Consult a tune-up manual for exact specifications.

How many ohms should a spark plug wire have?

What does the MM mean on spark plug wires?

A: The 8mm is sufficient for most street applications. Our ThunderVolt 50 10.4mm wire is especially recommended in high-boost/extreme-cylinder-pressure applications but will work fine on any engine. The thicker wire diameter provides a wider margin of safety to prevent voltage leaks.

What diameter spark plug wire is best?

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. In which case, a 5 or 7mm wire might be a better option.

Are high performance spark plug wires worth it?

Running on bad spark plugs or spark plug wires can end up using more fuel. High-quality wires will allow the spark plugs to start faster and keep your engine running more effectively. Save money. Routinely swapping out your spark plug wires can save you cash.
