Improve your Sierra's throttle response and give your truck a more energized feel with our different Sierra throttle bodies and accessories. The throttle body in your pickup truck controls how much air flows into the engine in response to the throttle being pressed down by the driver. This simple valve system opens and closes as you press the gas pedal, powering up the engine as necessary. A simple way to boost performance after making additional changes to your truck's engine is to install new Sierra throttle bodies. An upgraded throttle body will allow more air to flow through to your engine so that you have more to work with. This isn't all that helpful with a stock engine, because the basic throttle body is designed to work perfectly with the stock engine components. If you upgrade your engine with something like a supercharger, and you add on some additional truck intake parts or boost the exhaust system, you can see a nice response by investing in a better throttle body as well. We also offer Sierra throttle body spacers that can enhance performance a bit more by increasing the overall volume of air that's held by the system. There are so many slight upgrades that you can make to your pickup truck that you have lots of options to work with. The important thing to remember is that you need to invest in quality parts that will improve performance in the most notable way. That often means investing in multiple upgrades at the same time to get the biggest overall benefits. Add on some engine parts and make the most of your truck and the performance that it can offer you.
