GMC Sierra Throttle Bodies & Accessories

If you’re interested in putting a new spin on things, the rotating air flow created by 1999-2018 throttle bodies & accessories for your GMC Sierra may be just the thing you need. These finely manufactured components make the air whirl as it enters the combustion chamber, mixing it more thoroughly with the fine fuel droplets sprayed from the injection nozzles and creating a hotter, more even, more thorough combustion. That translates into more power – in both horses and torque – in the mid-range area of your truck’s RPM gauge, one of the most heavily used bands in many cases. The throttle bodies you’ll find on AmericanTrucks are picked for their sturdiness and precision – cut out of aerospace grade billet aluminum, these parts fit so well you can install them in less than hour. Get a boost to your truck’s performance and engine sound today!
