What’s a solid core spark plug wire?
Solid Core: Solid core spark plug wires typically utilize stainless steel or copper, which conducts electrical current very well. For that reason, solid core wires have lower resistance than other wires to get maximum energy to the plugs.
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.
What kind of spark plug wires do I need?
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.
Do MSD 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.
How do I know if my 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.

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.
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.
Which is better iridium or platinum spark plug?
Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
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.
Will bad spark plug wires throw a code?
Bad spark plugs can cause your engine to misfire. The engine’s computer uses sensors to detect these misfires and will create a code that turns on the check engine light.
Are high performance spark plug wires worth it?
Benefits of Spark Plug Wires
Stronger and more durable cables hold the spark until it finds its way to the spark plug to boost the performance of your vehicle. Improve gas mileage. … High-quality wires will allow the spark plugs to start faster and keep your engine running more effectively. Save money.
Are ignition wires the same as spark plug wires?
The ignition cables, also known as “spark plug wires” are part of the ignition system. They transfer the spark from the distributor or ignition coil to spark plugs that ignite the air-fuel mixture, starting the engine.
Are MSD wires worth it?
Companies like MSD, Taylor, and others may have a better wire set over OEM that are the stock wire size. The 8.5mm wires will not fit in the factory wire looms. And no, at least in a stock engine, they are not worth 2x the price of oem wires.
