Throttle Body Spacers

What is a Throttle Body Spacer and What Does it Do? 


Throttle Body Spacers work by swirling the air coming through the intake to maximize the airflow going through it. It is a generally inexpensive inch-thick piece of metal that bolts up directly to your throttle body.



An aftermarket air intake can help increase the airflow even further, and in turn increase engine horsepower, torque and even fuel economy. Many people will even port their throttle body and/or intake manifold, to maximize airflow even more.

Throttle Body Spacers are just one of many aftermarket performance accessories that Lou’s Muffler and Brake can install onto your vehicle. Call for a free quote today
