2018 Silverado 5.3 horsepower increase

Everyone wants to personalize their car in one way or another, especially Silverado. Due to its growing popularity, Silverado has replaced average cars in garages across the country. The original horsepower the manufacturer offers in the 2018 Silverado is adequate, but there is always room for more.

Let’s be honest; all of us want to know more about increasing the torque and horsepower of our cars. The excellent news with Silverado is that it is open to upgrades, especially in upgrading the horsepower.

In terms of horsepower, Silverado is already a beast. But here are a few ways by which you can increase horsepower and achieve more from this beast.

Upgrading the air intake system

You must be thinking what’s the relationship between the air intake system and increasing horsepower. There is a connection between the two. Although the air intake system might seem trivial from our viewpoint, simply redirecting air into the throttle body makes a considerable difference. You will feel a horsepower increase of roughly 5 to 20 horsepower.

All you have to do is to introduce a new air intake system to a performance filter. Upgrading the air intake system is an excellent way of improving horsepower, fuel economy, and intake sound.

The Turbo kit

A Silverado turbo kit is the most efficient and expensive method of enhancing the horsepower of Silverado 2018. With this method, you’ll experience immediate engine power gains. The components of the turbo kit force air into the machine, enhancing its power and torque.

The increase in horsepower depends on the component of the Silverado 2018 turbo kit. If you use a turbocharger, the horsepower gains will be up to 70 to 150. Whereas, if you use a supercharger, you can enhance the power by 50 to 100 horsepower.

Also, a turbo kit is not something you go, see, buy and install. Buying a turbo kit for Silverado requires research, budget and planning. Without the installation cost, the Silverado turbo kit may cost you from $4k to $8k.

Ca-back exhaust system

A cat-back exhaust system enhances the function of the catalytic converter. It makes more room for fuel and hence improves the engine’s power. The gain in horsepower depends on the existing exhaust system of your Silverado.

Computer reprogramming and chips

Another way to achieve decent power gains is by using performance chips and turners. They allow you to reprogram your vehicle. This way, you can control fuel mixture, fuel injection timing, valve timing, spark timing transmission shifts, etc. With a change in all these settings, you will witness an improvement in the engine’s power.


All the modifications, as mentioned earlier, are decent technical modifications that can considerably enhance the horsepower of the 2018 Silverado 5.3 L engine. However, it would help if you remembered that no way on Earth could give Silverado wings to fly, as all the technical modifications have their limitations.
