3 best spark plug wires (2019)



[ad_1]

Advantages of candle wires

  • Increase engine performance. The best spark plug wire will instantly spark the candle of your vehicle. Standard OEM cables can work very well when you start your car, but they will eventually weaken and lose their ability to start your engine properly. This could lead to misfires, slow idling and lack of power. Stronger and more durable cables hold the spark until it finds its way into the spark plug to improve the performance of your vehicle.
  • Improve the consumption of gasoline. The use of faulty spark plugs or spark plug wires can result in higher fuel consumption. High quality cables will allow the spark plugs to start faster and allow the engine to run more efficiently.
  • Save money. Regularly exchanging your candle wires can save you money. Driving on faulty cables can damage your vehicle if you do not disconnect the cables quickly enough. You also risk getting hurt with the spark plugs, which will result in a much larger repair bill.
  • Reduce radio frequency interference (RFI). The spark plug wires are made of carbon, which gives them a higher resistance to other electronic frequencies. This reduces the radio frequency interference generated by the normal operation of the ignition system. RFIs can impact radio reception and interfere with sensors and computer systems in the car.

Types of candle wire

Resistance wires distributed

These threads are made of fiberglbad impregnated carbon core threads and are the most common thread set in today's vehicles. This is the carbon that gives the wires greater resistance to RFI noise.

Magnetic resistor wires / inductance wires

Magnetic resistance spark plug wires, or inductance wires, are more popular in Japanese style vehicles such as Acuras, Toyota and Hondas. They are made from spiral cores wound with a nickel alloy or copper wires. The material is less resistant to electric current, which means that it requires less current to generate a spark.

Fixed resistance wires

Fixed-resistance spark plug cables are more prevalent in European-style cars. They are composed of steel wire and copper and resistances in the candle caps.

Price of candle wire

  • $ 30 to $ 40: Spark plug wires do not really vary much in price. As a general rule, you can find one of the best spark plug cable sets in this price range. They will come with several wires to connect to several candles.
  • $ 40 and over: It is in this price range that you will find spark plug cables with enhanced features, such as anti-corrosion or improved spark plug retention for easier installation. These are also made of a more durable material than the cheaper products.

Main characteristics

Compatibility

The choice of new spark plug cables really depends on the type of vehicle you drive. If you use your car as a driver on a daily basis, distributed resistance cables are your best choice. They are specifically designed with a reduced amount of RFI and will not interfere with your onboard computer, sensors or gauges. If your vehicle is American-made, opt for distributed resistance cables. A Japanese car will require strong magnetic cables and European vehicles will work more efficiently with fixed-resistance cables.

Number of spark plugs

It is also important to know how many spark plugs your vehicle has. Some candle wires are divided into several wires to fit multiple candles, while others can be purchased separately. The more cars you take, the more wires you will need.

other considerations

  • Length: You will need to know the distance between the dispenser or ignition and the candles. The wires of the ignition cable vary in length and must be able to reach the spark plugs and the ignition to properly transfer a spark to the spark plugs.
  • Order: Make sure to properly connect the spark plugs in the order indicated on the spark plug wires. This can be done by checking the wires for the numbers or the color code.

Best recommendations and recommendations of 2019 spark plug wire

Best Spark Plug Wire: NGK Spark Plug Wire Set

The NGK spark plug cable range features variable pitch winding and ultra-low resistance. They provide a powerful spark to the spark plugs for an instant and powerful start. The wires are also equipped with a positive lock and resist corrosion. Their stainless steel ends fit snugly to the spark plugs for fast, vibration-free ignition.

One feature that we have found useful is that each wire is numbered for easy identification and use of each candle's identification system. Each is also color coded so you can tell which thread is connected to a given candle. The wiring is composed of a high temperature silicone sheath that resists moisture, oil, gas and crack under extreme heat up to 482 degrees Fahrenheit.

Although these spark plug wires are an excellent replacement for the original wires, we found that the spark plug caps may not be properly covering the engine cylinder head sleeves. This could lead to dirt and water penetrating the plug sleeves. Another disadvantage is that they are more expensive.

Best Value of Candle Wire: Denso Candle Wire Set

Denso's premium spark plug cable sets are identical to the OEM style designed for most vehicles. This makes them familiar and easy to install after removing old ones. The main difference lies in the materials, such as the wire, that make up these replacement wires. These are much more durable than the standard wires supplied with your car.

The threads are designed with a fiberglbad braid that quickly and efficiently sends a spark to your candles. The casing for copper wiring and cabling is sturdy and thick to help prevent punctures and extreme cold or heat. Another benefit is that the cables are a bit cheaper than the exact matching game found in your vehicle.

A disadvantage of the Denso candle wire is that it may be a bit too short to reach the OEM routing clips. However, you should be able to stretch them to fit properly. You may also have trouble locking the engine-side seal.

Honorable Mention of the Best Candle Wire: ACDelco Professional Candle Wire Set

ACDelco's professional spark plug cable set works well with spark plug and ignition, giving your car the maximum voltage needed to start operating throughout your journey. Specially designed dispenser shaft shape and materials allow for secure fit, easy installation and tight seal.

The corrosion resistance feature helps prevent acid buildup, while the terminal design improves spark plug retention and helps you install each wire properly. In addition, the insulation acts as a highly dielectric solution, keeping the copper in excellent shape every kilometer. In addition, the coil retainer prevents friction and micro-arcing in the material.

A word of warning to those who remove them yourself: the wires may push until it's almost impossible to remove them until after the candles without separating the connector metal from the inside of the sheath. You may need to have them removed by professionals when replacing wires. Another problem you can find is that the wires can be a little too short in some cars.

Advice

  • We recommend that you have information about your vehicle when you buy new spark plug cables or spark plugs. This will allow you to select the right cables for your vehicle. You can find this information in your owner's manual or on your registration card.
  • Since you are replacing candle wires, it is also wise to replace your candles. Defective wiring can damage the plugs. Therefore, disconnecting the plugs at the same time will help maintain the life of your engine.
  • Remember to inspect your spark plug wires from time to time to make sure they are in good condition. Finding signs of wear could lead to faulty starts, misfires or other engine damage.
  • You can use a dielectric compound to cover the wire connection and the insulator where the boot is located. The compound resists the effects of corrosion and prevents boots from sticking to the insulation, which can damage the wires and possibly cause them to break during future maintenance operations.

FAQ

Q: How often should I change the threads of the candle?

A: We recommend that you change your spark plug cables every 30,000 to 50,000 miles. However, it also depends on the type of conduct you need to do. But if you are driving cars or taking your vehicle off the road, you may want to consider replacing the cables earlier. You will often want to inspect the candle wires to make sure they are in good condition.

Q: How do I know if a candle wire is getting worse?

A: There are several signs that your spark plug wires need to be exchanged for a new pair, including hesitations or contractions during acceleration, reduced acceleration, slow idling, carbonization at the end of the cable that connects to the spark plugs, a significant drop in fuel economy or difficulty starting your engine.

Q: Is there an appropriate way to connect the wires?

A: You will need to route the cables correctly to the appropriate spark plug to make sure your engine starts properly. Poor routing of the wire could create misfires in the engine, which is both boring, powerful and surprising. To guide you in the right order, the threads will be labeled or color-coded.
