What is a throttle body spacer and how does it work?

A throttle body spacer installs between your throttle body and intake manifold. It creates a controlled turbulence in the air entering the engine, which can help improve airflow and combustion efficiency.

What material is the aFe Silver Bullet Throttle Body Spacer made from?

The spacer is constructed from durable T-6061 billet aluminum. This material is chosen for its strength and resistance to corrosion.

Does this throttle body spacer come with installation hardware?
