aFe Silver Bullet Throttle Body Spacer – 2007–2013 BMW 328i (E90/E91/E92/E93) 3.0L N52 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 46-31011 for the 2007–2013 BMW 328i (E90/E91/E92/E93) 3.0L N52.

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 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 2007–2013 BMW 328i (E90/E91/E92/E93) 3.0L N52, we would make the purchase decision around the limitation this component addresses and how it fits with the car's current and planned modifications.
