aFe Silver Bullet Throttle Body Spacer – 2011–2022 Toyota Corolla

aFe Silver Bullet Throttle Body Spacer – 2011–2022 Toyota Corolla modify the inlet path immediately ahead of the throttle body using a vehicle-specific bolt-on spacer. This listing is built around aFe POWER part number 46-38015 for the 2011–2022 Toyota Corolla.

aFe Silver Bullet spacers are supporting induction components. Their design is intended to influence airflow at the throttle-body entry while preserving a reversible installation with application-specific hardware.

What This Means on the Car

We would not treat a spacer as a replacement for an intake, tune or major airflow modification. Its appeal is the simple installation and its ability to become one small part of a broader induction package.

Fitment & Part Numbers

Application: 2011–2022 Toyota Corolla
aFe POWER part number: 46-38015

Fitment can differ by engine, drivetrain, trim, factory equipment, emissions configuration and production date. Match the part number above to the vehicle before installation; where aFe publishes SKU-specific installation or emissions requirements, those requirements take precedence.

Legacy Racing Enthusiast Perspective

This is best for the owner who understands it as a supporting bolt-on rather than expecting the type of change associated with a complete intake or calibration. On the 2011–2022 Toyota Corolla, we would make the purchase decision around the limitation this component addresses and how it fits with the car's current and planned modifications.
