• Uses all factory throttle body mounting locations - no drilling or permanent modifications required.
• CARB EO# D-550-17/D-550-47 - 50-state legal for most listed applications. Certain Engine Test Groups are excluded; verify CARB EO for your specific model year before purchase in California.
• Dyno-proven gains of up to +8 HP and +7 lbsxft torque.
• 2-Year Limited Warranty.

Features

• Combination serrated/helix entry design creates controlled intake turbulence in the combustion chamber for more thorough air/fuel mixing and a more complete combustion cycle
• Serrated edge design eliminates the intake whistle commonly associated with helix-only throttle body spacers
• Lengthens the intake tract to increase intake air velocity, improving throttle response and performance
• Increases plenum volume between the throttle body and intake manifold for improved volumetric efficiency
• Precision CNC machined from 6061-T6 billet aluminum - lightweight, high strength, precise fit and finish
• Installs using factory mounting locations - direct bolt-in with no modifications required
• Performance gains increase further when combined with an aFe Takeda intake system

Product Description

The aFe 46-37002 Silver Bullet Throttle Body Spacer is a direct bolt-in upgrade for Honda and Acura V6-powered vehicles fitted with 3.5L or 3.7L J-series engines - covering a wide range of platforms including the Honda Accord, Odyssey, Pilot, and Ridgeline, and Acura TL, TLX, MDX, TSX, RL, RLX, and ZDX. It installs between the factory throttle body and intake manifold, lengthening the intake tract and increasing plenum volume to improve volumetric efficiency and intake air velocity at the point of throttle body entry.

The serrated/helix combination design creates controlled turbulence in the incoming air charge, promoting more thorough air/fuel mixing before combustion - translating to dyno-proven gains of up to +8 HP and +7 lbsxft of torque. The serrated edge specifically addresses the whistling noise commonly associated with helix-only spacers. Installation uses all factory mounting locations with no drilling, cutting, or permanent modifications. Performance gains increase further when paired with an aFe Takeda Stage-2 intake system (TR-1007B/P or TR-1021B-R/P-D). CARB EO# D-550-17/D-550-47 covers most listed applications for 50-state street legality - verify excluded Engine Test Groups for California compliance.
