aFe 46-31002 Silver Bullet Throttle Body Spacer Kit BMW N54 3.0L Turbo

The aFe POWER 46-31002 Silver Bullet Throttle Body Spacer is a precision-engineered performance upgrade designed for BMW N54 3.0L turbocharged engines. By creating turbulence in the airflow just prior to entering the engine, this spacer helps increase horsepower and torque while delivering noticeably improved throttle response and fuel efficiency.

Serrated/Helix Design:

Unlike basic helix-only spacers, the Silver Bullet uses a patented serrated/helix combination entry. This unique geometry creates intake turbulence inside the combustion chamber, breaking up the fuel charge for a more complete combustion cycle — and it eliminates the intake whistle commonly associated with helix-only designs.

Key Features:

• 6061-T6 Billet Aluminum Construction — CNC-machined for precise fit, light weight, and long-lasting durability
• Serrated/Helix Entry Design — Creates beneficial intake turbulence while reducing whistle noise
• Extended Intake Track — Lengthens the intake path to increase air speed and boost performance
• Improved Throttle Response — Delivers a more immediate and responsive feel under acceleration
• Complete Kit — Includes all necessary hardware and components for installation
• 50-State Legal — CARB Executive Order D-550-11 compliant; emissions legal in all 50 states
