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.
Also the question Is, does it matter what spark plug wires you 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.
Also, what are the best spark plug wires made of? 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.
Correspondingly, are performance spark plug wires worth it? 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.
Moreover, 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.
Are bigger spark plug wires better?
That thicker wire core provides a lower operating resistance, allowing more spark energy at the spark plug. This thicker core, once wrapped in the insulating material and outer jacket, is what dictates the larger overall spark plug wire diameter.
Are Blue Streak spark plug wires any good?
Blue Streak’s patented conductor offers low-resistance wire (15 OHM/FT) and allows for a hotter spark with greater spark duration – resulting in more power to the plug and greater combustion efficiency. … This coating also reflects heat and makes the wires easy to clean so they always look great!
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.
What’s the best spark plug for performance?
Iridium. The best spark plugs on the market boast an iridium construction. Iridium spark plugs give you even better gas mileage, performance, reliability, and longevity than double-platinum plugs.
Are Iridium plugs worth it?
Iridium is about six times harder than platinum, eight times as strong, and has a higher melting point at several hundreds of centigrade. These characteristics make it 25% more durable than platinum plugs. With this plug type, you’ll never have to worry about wear; you can trust it to offer long-lasting performance.
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.
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.
Do HT Leads improve performance?
Performance HT Leads are Worth it As soon as the flow is interrupted, the magnetic field collapses, creating or inducing a higher voltage in the secondary set. This is the current that then gets directed to the spark plugs.
Are 7mm plug wires good?
Plug wires are often advertised by the diameter of the wire, making it easy to look at the options for plug wires and immediately think if 7mm is good, 8.8mm must be great. … Those larger wires typically have a lower resistance per foot—and this, not size, is the key thing to pay attention to.
