Do better spark 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.

Does it matter what kind of spark plug wires you use?

Does size matter? For overall spark transfer, not necessarily. However, thicker wires, like these Moroso Super Max II 11mm wires, can provide added RFI suppression and insulation. … That’s why it’s important to select a good quality set of spark plug ignition wires to deliver juice to your spark plugs.

Will spark plug wires improve performance?

The short answer is Yes, when you replace the spark plugs and wires can increase your vehicle’s performance. New spark plugs help keep your engine at its peak performance and efficiency levels. … Worn or dirty spark plugs require higher voltage to get a strong enough spark to start a vehicle.

Are expensive 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.

What is the difference between 7mm and 8mm spark plug wires?

8mm spark plug wires are a heavier gage wire than the 7mm type. … The thicker wire has a thicker core. The core is the part of the wire that brings power to the spark plugs. A more robust core provides a lower resistance path for the power, thereby allowing more power to reach the spark plugs.

Are Iridium plugs worth it?

Iridium spark plugs are better at starting engines than other types of spark plug because the spark is highly concentrated in the central electrode, and consequentially requires less voltage to operate. This makes ignitions faster and more reliable, and also reduces power consumption.

Can spark plug wires add horsepower?

In short, yes, in some situations spark plugs can increase horsepower. … The theory behind spark plugs increasing horsepower is that by providing more spark to the firing tip of the spark plug, it will (and does) combust more fuel.

Are MSD wires good?

These wire are extremely high quality. When tested with an ohm meter prior to installation, they registered @28 ohms. The stock wires were Delco, and registered over @800 ohms.

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.

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.

Should spark plug wires have high or low resistance?

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.

Are thicker plug wires better?

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.

Do Iridium spark plugs increase horsepower?

Iridium plugs take less voltage to fire which results in more coil dwell time. That translates to better combustion, lower emissions, better fuel economy and more horsepower. Lower your costs. It’s true – buying an upgraded plug does cost more than a basic spark plug.

How long should spark plug wires last?

A quality set of spark plug wires can generally last around 60,000 to 70,000 miles. Again, it is a good idea to replace these parts prior to a failure, like a misfire. A vehicle that is running rough or misfiring can cause catalytic converter damage.
