What To Consider Before Buying The Best Spark Plug Wires for Chevy 350 with headers? 

Keeping the engine functioning depends on spark plugs. These plugs also make it possible for you to ride smoothly. Moreover, you won’t have to buy the accessories frequently. That’s why Chevy 350 plug wires must be chosen carefully. As I mentioned in my last post, there are several key considerations you should take into account before purchasing a spark plug wire or header for your car. You can still follow the buying guides if you have some other car models in your collection.

Go Through The Basic Information

Find out as much information as you can about your vehicle first. The right accessories can always be chosen if you know the necessary information about the vehicle. 

It’s no exception when it comes to picking the perfect spark plug wires! Just check out the owner’s manual! This will tell you what type of plugs you need. We are always happy to help you on the internet if you cannot locate something in a manual or, worse yet, lost it. 

Types Of Spark Plug Wire And Compatibility

Distributed resistance wire: The type of plug wires is the most commonly used wire sets in advanced motor vehicles. They are made of fiberglass-impregnated carbon core wires. With carbon material present in the wires, they provide better resistance to RFI noise.

Magnetic resistance wire: The wires are also known as inductive wires. They are designed with nickel alloys or copper wires from spiral cores wound. The cables are less resistive to electricity. As a result, less current is required to generate a spark.

Fixed resistor wire: The wires are made of steel and copper. They include resistors in the plug boots.

The type of plug wires you’ll be using largely depends on the type of vehicle you drive. For the Chevy 350 or other American cars, you can use the distributed resistance wires. Generally, experts suggest using magnetic resistant wires for the Japanese cars and fixed resistor wires for European cars.

Number And Length Of Spark Plug Wire

In order to buy the right number of plug wires, you must know how many spark plugs are installed in the car. A spark plug can connect to multiple wires, so some wires split. The rest of the spark plug wires must be purchased separately. 

A way to estimate the number of cylinders in a car is either counting the wires installed or looking at the number of wires. The total number of wires to buy depends on the number of cylinders.

A distributor’s distance from the plugs should also be known. You have to make sure that your cable can reach the plugs as these wires are available in a variety of lengths. 

Experts recommend larger cables regardless of whether the spark’s energy is determined by the cable’s size. Larger cables are better insulated. Consequently, more spark is delivered to the plugs. Less gas leakage means better mileage. 

Heat tolerance matters! 

Higher heat tolerance of the wires is important. If you use a very hot coil, which is probably made of cheap materials, it may meltdown very easily. This may result in misfires.

So, choosing spark plug cables with higher heat tolerance is important for your car. Usually, high-quality wires cost more than the average but come with better insulation materials.

Other considerations

You must also consider your budget when purchasing spark plug cables. It is not uncommon to find wires in the $30-$40 range. As a result, the quality cables are easily affordable. But, you won’t buy the plug wires very often, will you? Isn’t it reasonable to spend a few extra bucks on premium cables? Premium cables offer more features.

While choosing the best plug wires for Chevy 350, you should also take into account the chemical resistance, RFI suppressions, boot types and angles, Ohm rating, etc. 

You can deal with an expert if you are a beginner and do not know enough about your vehicle’s technical issues. You might have to spend some money to learn the problem.
