aFe 46-31007 Silver Bullet Throttle Body Spacer

The aFe Power 46-31007 Silver Bullet Throttle Body Spacer is a precision-engineered intake upgrade designed to increase horsepower, torque, throttle response, and fuel efficiency. By generating controlled turbulence in the airflow just before it enters the engine, this spacer optimizes the combustion cycle for measurable, dyno-proven performance gains.

Key Features:

• Dyno-Proven Performance Gains: Delivers up to +6 HP and +13 lb-ft of torque in testing when paired with an aFe OER air filter and dynamic air scoop.
• Patented Serrated/Helix Entry Design (US PAT 07055513): Creates controlled turbulence in the intake manifold, increasing air pressure in the combustion chamber for a more complete burn cycle — resulting in stronger performance and improved throttle response.
• Reduced Intake Whistle: The combined serrated and helix bore design eliminates the annoying intake whistle commonly produced by helix-only throttle body spacers.
• Longer Intake Tract: Adding this spacer extends the intake tract, which increases air intake speed for improved volumetric efficiency and throttle response.
• CNC-Machined 6061-T6 Billet Aluminum Construction: Precision machined from aerospace-grade 6061-T6 billet aluminum for lightweight strength, a perfect fit, and a high-quality finish.
• Custom Hardware Included: Comes with custom-machined screws engineered specifically for the application, allowing a secure, factory-like fit without damaging the intake manifold.
• 50-State Legal: Emissions compliant in all 50 states — CARB EO Number D-550-11.
• 2-Year Limited Warranty

The aFe Silver Bullet Throttle Body Spacer is compatible with OEM and aFe POWER cold air intake systems, making it an easy bolt-on upgrade for drivers looking to extract more performance from their engine.
