About Throttle Body Spacers
Throttle body spacers, or TBI Spacers, spin the air that comes through your air intake down into your engine. This process facilitates a better mix with fuel for cleaner, more efficient combustion. Better still, you can use these with both performance and factory Scion xB Air Intake Systems, or any other compatible air intake system, depending on the size of your sought-after power gains.
You can easily find one of these versatile TBI Spacers for use with your Nissan Sentra air intake as well as ones for a host of other vehicles, at AutoAccessoriesGarage.com. We have everything you need to get the most out of your engine, including a helpful Customer Service team that can answer any questions that pop up along the way.
