What diameter are spark plug wires?
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.
Can touching spark plug wires cause misfire?
Yes, touching the spark plug wires when the engine is running can cause a misfire. The most common causes of this problem are physical damage to the electrode or insulator surfaces and dirt accumulation on these parts which prevents sparks from being created.
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.
Do spark plug wires add horsepower?
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. Of course, every vehicle on the road will misfire from time to time.
Does the length of spark plug wires matter?
What is even more imperative than matching cable length is that you do not mix up the order of the spark plug wires. Improper installation of these wires can result in poor combustion or misfiring of the cylinder, which will cause drivability issues and potentially severe damage to the engine.
How much heat can a spark plug wire handle?
The heat range must be carefully selected for proper spark plug thermal performance. If the heat range is not optimal, then serious trouble can be the result. The optimal firing end temperature is approximately 500°C (932°F) to 800°C (1472°F).
Are NGK Spark Plugs worth it?
NGK 6619 Iridium IX Spark Plugs snagged the top pick in our spark plug comparison because they offered the best mix of high-performance, fuel efficiency, durability, and dependability. Featuring an iridium construction, these high-quality spark plugs provide a longer lifespan than copper and platinum spark plugs.
Where can I buy spark plug wires for my car?
Visit O’Reilly Auto Parts for spark plug wire holders, spark plugs, or spark plug wires that are right for your vehicle.
How does a spark plug wire holder work?
Touch device users, explore by touch or with swipe gestures. A spark plug wire holder keeps the spark plug wires separated and safe from the hottest part of the engine or metal contact. Spark plug wires that rub against metal may eventually wear down to the core, causing arcing.
What are the dangers of spark plugs?
Spark plug wires that rub against metal may eventually wear down to the core, causing arcing. This can cause additional damage to the wires and engine misfires, as the power doesn’t make it all the way to the spark plug.
