Does spark plug wire brand matter?
The engine won’t know the difference. All spark plug manufacturers cross-reference their plugs with other brands so their brand can be interchanged with other brands. … What’s really important is making sure your customers get the correct spark plugs for their engine regardless of the brand.
What’s the best material for 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.
How do I choose spark plug wires?
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.
Are bigger spark plug wires better?
Resistance: Rated in ohms-per-foot, resistance is the ignition wire’s tendency to resist the flow of the electric current. Wires with higher ohms-per-foot ratings will allow less current to flow from the spark source to the plugs. This can affect engine performance and fuel economy in a negative way.
Do upgraded 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.
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.
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.
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.
