One of the easiest additions to improve low end horsepower and torque to your VQ37 is the Silver Bullet Throttle Body Spacers. The TBS has both a Serrated and Helix combination design, which creates air turbulence in the intake manifold, increasing the air pressure in the combustion chamber. This design also reduces intake whistle that occurs with other helix-only designs. Kit comes with two spacers to work with the VQ's dual throttle body design.

• In-house Dyno testing resulted in max gains up to +6 HP and +7 lbs. x ft. of torque 
  (Tested on 2012 Nissan 370Z V6-3.7L)
• Billet Aluminum 6061-T6 Construction
• Serrated/Helix Combination Design for optimum airflow into the combustion chamber, precision machined from 6061-T6 aluminum (US PAT 07055513)
• Ease of installation
• Consist of 2 Spacers

Serrated/Helix Design:
The Serrated/Helix design creates air turbulence in the intake manifold. This turbulence increases the air pressure in the combustion chamber resulting in increased horsepower, torque and improved throttle response. The Serrated/Helix combination design also reduces intake whistle that occurs with other helix only designs. (US PAT 07055513)
