What is the reason for using fine wire spark plug?

Massive. For turbocharged piston twins flying at high altitude, fine wire spark plugs are more effective at igniting a fuel air mixture. They induce less strain on the magnetos and simply prove to last longer.

What are the advantages of fine wire iridium electrodes?

Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs. Iridium spark plugs feature a fine wire center electrode that is designed to conduct electrical energy better and increase firing efficiency. There is a price for this precious metal.

Does it matter what 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.

How do you clean fine wire spark plugs?

Fine wire spark plugs normally don’t need much cleaning. However, if you do need to get the lead out don’t pry against the electrodes or insulators. If you blast the spark plug, use only high grade, new, spark plug abrasive. Use the lowest pressure possible and blast for only a second or two.

Do thicker spark plug wires make a difference?

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.

Do Iridium spark plugs increase horsepower?

Increase your performance.

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.

How often should Iridium spark plugs be changed?

Iridium or platinum-tipped spark plugs – also called “long life spark plugs” should be changed 60,000 and 150,000 miles, depending on the owner’s vehicle.

What are the signs of a bad spark plug wire?

Signs of Bad Spark Plug Wires

  • Visible Damage on the Spark Plug Wires. Spark plug wires may start to dry out over time, so look for cracks in the insulation. …
  • The Engine is Idling Rough. The car should have a smooth and steady idle, but the engine may develop a rough idle if the spark plug wires are bad. …
  • Engine Hesitation. …
  • Engine Misfiring.

Will new spark plugs and 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.

How do you know if your spark plug wires are bad?

Common signs of failing spark plug wires include a decrease in power, acceleration, and fuel efficiency. In addition, the engine light coming on or visible damange to the cables can be signs of a failing wire.

What is a fine wire spark plug?

Fine wire plugs have a single, small-gauge wire ground. Iridium is the most common material because it’s resistant to the inevitable erosion. There’s no free lunch, however; iridium is expensive, so fine wire plugs cost two to three times more than massives.

Can spark plugs be serviced?

The good thing is, spark plugs are easy to repair, maintain, and if necessary, replace. We will explore the steps to inspect and service your spark plugs. With this information, you can then decide whether or not you want to replace your spark plugs.

Do 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.

What size spark plug wires should I use?

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.

How many years do spark plug wires last?

The ignition cables on a car are made to last about 60,000 miles before they have to be replaced. In some cases, the wires will need to be replaced due to the rubber boots on the end getting damaged and now allowing for a good connection with the spark plugs.
