The best Chevy Silverado 5.3 performance upgrades

Since the Silverado has replaced the car in many garages, it only makes sense that we would want to personalize it. Additionally, the truth is that no one wants the exact vehicle as the neighbor, and all of us want more know how to increase the horsepower and torque for our Silverado. You’ll be happy to know that your Silverado responds well to upgrades, regardless of its age or powerplant, and there’s considerably more power available for the road or trail if you’re willing to tap it.

1. How to add horsepower to a 5.3 Silverado

Chevy Silverado Air Filter and Air Intake Systems

When your nose is stopped up and your chest congested, you don’t get a lot of air. As a result, it makes a massive difference in how hard you can go in your workouts. The same is true for your 5.3L Silverado. The simple process of redirecting cooler air to your throttle body makes such a difference that you can see 5 to 20 HP gains. Tie a new air intake system to a performance filter, and you’ll also get better fuel efficiency and a more powerful intake sound.
