What is the best spark plug wire core material?
The majority of spark plugs feature a copper-core center electrode. Copper is an excellent conductor of electricity – better than any other type of material used in spark plugs – and also transfers heat faster.
Do high performance spark plug wires make a difference?
High performance spark plug wires are made to provide a lower core resistance, a greater resistance to engine heat and chemicals, and a higher degree of radio suppression. The wires also have heavier outer materials to prevent damage from heat and chemicals, and provide better radio frequency suppression.
Does it matter what kind of spark plug wires I use?
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.
How many ohms should a good spark plug wire have?
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.
Are thicker spark plug wires better?
That thicker wire core provides a lower operating resistance, allowing more spark energy at the spark plug. If the plug wire’s resistance is too high, the spark energy to the spark plug will decrease, causing poor performance and potential spark plug fouling.
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.
Can spark plug wires increase 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 can faulty spark plug wires cause?
When spark plugs wires fail, a host of engine problems can result.
- Rough Engine Idle. The most common symptom of bad spark plug wires is a rough engine idle.
- Engine Miss.
- Engine Hesitation.
- Reduced Engine Power.
- Engine Surging.
Does resistance matter in spark plug wires?
Resistance is the biggest buzzword when it comes to spark plug wires, but it usually comes at the cost of EMI and RFI suppression. And despite all the hoopla surrounding resistance, it will not typically make any difference in horsepower in an otherwise healthy and properly functioning motor.
What’s 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.
What are the factors to consider when buying a new spark plug wires?
Most of NGK’s spark plug wire sets use high quality EPDM and silicone coverings to resist heat, oil, and chemical damages for increased durability. Each spark plug wire features a positive locking, corrosion resistant stainless steel terminal end, ensuring tight fit and maximum resistance to vibration and separation.
