Best Spark Plug Wires for Smooth Ignition and Functionality

Spark plugs are an important component of the ignition system that is mostly the center of attention during car maintenance. However, the spark plug wires determine how efficiently the spark plug will function and directly affects the amount of voltage given out for ignition. Good wires will make the process fast and seamless, giving the spark plug enough power to put the pistons in motion. Let us look at the best spark plug wires for smooth ignition and better performance.

Factors to Consider Before Buying Spark Plug Wires

a) Insulation

Spark plug wires are installed in areas of the car with very high temperatures when the engine is on. Silicone jackets are good for keeping away cold during freezing temperatures. Double insulation is an added advantage when buying a spark plug wire. Insulation protects the wires against corrosives like chemicals or destruction from friction during vibration. Good insulation increases the cable life and efficiency.

b) Type of Wire

Different wires have different resistance capabilities. Copper wires have a different resistance from nickel. Look for the best wire with the lowest resistance that can give enough surge for ignition to take place. Consider cables with a resistance of between 40 and 50 Ohms.

c) Engine Specific

It would help if you bought a cable that is compatible with your car. Buying a spark plug wire that is not compatible will waste money because it simply will not work. The compatibility is written in the product description when buying online. Whenever you change your engine, look for spark plug wires specific to the engine and not the car.

d) Warranty and Return Policy

Not all the time will the parts be compatible or functional. A warranty gives you the chance to make adjustments or changes where it counts. A return policy can help you get a refund to buy the correct wires that will work on your car. A warranty shows how confident a company is in its products and shows that the products are quality and live up to the standards in the description.

e) Aftermarket Vs. Factory

It does not matter whether the spark plug wires are factory-made or not as long as they match your specifications. Look at the type of metal used to make the wires, the resistance, the cable jackets, and the functionality. Consider the functional properties more than the product name.

f) Length

Length is not a huge factor when it comes to buying new spark plug wires. However, length slightly affects the resistance. Resistance increases the longer the cable is, but not by levels that will significantly affect ignition.

g) Other Features

The best spark plug wire has other features that make everything easier to maneuver. Color-coded cables are easier to install and prevent electrical short-circuiting when turning on the ignition. Good cables have variable pitch winding that helps in canceling out radio frequency interference and delivers low resistance. Some cables come with dielectric grease that keeps the cables in shape and protected for durability.

Watch out for an inductance style plug wire because they have a spiral core and lower resistance. Wires need to be waterproof to prevent any accidents. Look for extra jackets to keep moisture and liquids away. Variable pitch wire winding breaks electrical waves that are created after ignition. A coil retainer prevents micro-arcing and fretting, keeping the wires functioning for longer.
