AFE: Silver Bullet Throttle Body Spacer Nissan Titan / Armada 04-15 / Infiniti QX56 04-13 V8-5.6L

Serrated/Helix Design: 
The Serrated/Helix combination design creates intake turbulence in the combustion chamber. This turbulence breaks up the fuel which creates a more complete combustion cycle increasing horsepower, torque and improving throttle response. The Serrated/Helix combination design also reduces intake whistle that occurs with other Helix only designs.

6061-T6 Billet Aluminum Construction: 
All Silver Bullet Throttle Body Spacers are constructed from 6061-T6 billet aluminum precision machined for lightweight, high strength and perfect fit and finish.

Longer Intake Tract: 
Adding a Silver Bullet Throttle Body spacer lengthens the intake tract which helps increase intake air speed increasing performance and improved throttle response.
