How to Get More Horsepower for the 2007 Chevy Silverado

by Colette McCormick

The 2007 Chevy Silverado comes with a variety of engine sizes ranging from the 4.3-liter with 195 horsepower to the 4.8-liter and its 295 horsepower, and finally, the 5.3-liter engine, which has 315 horsepower. The best way to improve the horsepower of whichever engine you choose is to replace some of the stock components with modified versions. It involves some extra investment on your part, but increasing the horsepower of your engine will make it will run more efficiently, giving you better fuel economy so that the modifications will pay for themselves.

Replace the stock air intake system with one designed to provide better horsepower. It does this by filtering dirt out of the air that flows through your engine, allowing the air to flow better. An engine that has more air moving through it runs at a cooler temperature and is therefore more efficient. Improving air filtration can give you up to 10-percent more horsepower.

Change the standard exhaust that the truck came with. An exhaust with a high-flow muffler will give you more horsepower by letting the air out of the engine quicker. Increasing the diameter of the exhaust pipe will also improve airflow.

Change the spark plugs to make the engine perform better. Badly sparking plugs can severely reduce the horsepower that you get from your engine. Check the owner's manual to confirm the recommended sparking distance, and check the plugs regularly to ensure that they are in good condition.
