What to Consider Before Buying the high performance coil packs for 5.3 vortec

If you go through our top ten ignition coils list, now you might be educated regarding how to buy a proper ignition coil pack.

But remember, there are a lot of other variables you need to consider before purchasing any ignition coils. We are going to talk about those factors in this section.

So, we recommend that you go through these factors before any purchase.

Besides, it will be easy to find the 5.3 coil pack upgrade after this. This section will talk about factors like engine type, shape, customer service, and many more.

Engine Type

Specific ignition coils are produced specially for the 5.3L Vortec engine, and some coils might even fit with other engine types. For instance, QYL Ignition Coil Pack supports 5.3L to 8.1L engines.

But, if you are looking for an ignition coil for a 5.3 Vortec engine, make sure to buy matching ignition coils.

Therefore, we highly recommend doing some research before buying an unknown product.

If you can stick to the above ten best 5.3 coil pack upgrades, it will be great because all the above ignition coils support a 5.3 Vortec engine.


Another thing you should consider is the shape. You already know that there are two types of shapes from our Product Reviews section:

Round shape and square shape. But, the most modern trucks come with square-shaped ignition coils.

And the older models with round-shaped ignition coils. So, before buying, keep that in mind.

Besides, square-shaped coils won’t fit with vehicles that have round-shaped coils and vice versa.

Moreover, not all round-shaped coils and square-shaped coils are the same.

There might be a difference here and there. So, it is always better to check with your truck’s model before jumping to a conclusion.

Spark Plug Cable

When your engine fails to perform at a usual standard, there might be an issue with the ignition coils. But, it can be a result of a deteriorated spark plug cable.

When that happens, changing the ignition coils won’t fix the engine issue. You might have to replace the spark plug cables too.

Some ignition coil packs have a spark plug cable, and some don’t. For instance, BANG4BUCK Ignition Coil Pack includes a much-needed spark plug cable set.

So, buying a product like that benefits you immensely. Also, having an extra spark plug cable won’t hurt you.

DIY Factor

If you want to get the job done cheaper, buying an easy-to-install ignition coil pack is the best choice.

With the DIY installation process, you won’t need any professional support.

All you need to do is, read the given manual and follow it correctly. The installation will be completed without even you knowing it.

On the other hand, hiring a professional can cost you some serious money.

Also, there is no guarantee you will get the best possible service for that money, given that all mechanics are not equally skilled or talented.

Therefore, look into the DIY factor before buying an ignition coil.

Life Span

For any product, having a long life span is a must. The ignition coils won’t last much longer without proper anti-corrosive features or heat-resistant ability.

Therefore, you might have to replace them regularly; it will cost you a lot of money and time.

Also, try to choose a product that uses OEM standards because OEM parts have higher durability. Using OEM parts is crucial for a long lifespan.

Therefore, make your decision wisely and accordingly. Otherwise, you will end up with regular performance issues in your 5.3 Vortec engine.

Problem Solving

The primary purpose of the ignition coil is to improve your engine performance issues. A good ignition coil pack will fix the lack of boost, delay in response, lowered RPM, and many more.

So, your ignition coil upgrade should be capable of solving at least two or three engine issues. Otherwise, it is a pointless upgrade.

Some ignition coils are excellent for providing added boosts, and others are good for increasing mileage. So, picking the correct ignition coil can be tricky.

The best way to solve this is to inspect and recognize your truck’s engine issue before buying any product.

That way, you will know what you need to fix. It will make your decision much more straightforward.

Customer Service

It is always better to pick a reliable brand for your ignition coil upgrade. Because you never know when you need customer support.

Sometimes during the installation, you might need some help from customer support, even if the process is straightforward.

But, what happens, if the particular brand’s customer support service is not available?

Therefore, choose a brand that provides good customer support. It will make the installation process much easier.

More Must-Known Facts About Ignition Coils Before Buying

Quality of the Wire and Diameter: An ignition coil has two different windings: primary winding and secondary winding.

And the primary winding wires should have a larger diameter than the secondary winding wires. Some manufacturers tend to reduce the quality of the wires and the diameter.

These can lower the ignition coil’s ability to withstand vibration and heat. Therefore, make sure to buy ignition coils that have quality wire and higher wire diameter.

Epoxy Resins Quality: The primary and secondary winding should be separated in a proper ignition coil. Most manufacturers use epoxy resins to create this barrier.

So, using high heat and vibration resistant resins is very important. When buying a new ignition coil, remember to check the epoxy resin’s quality.
